* Mechanical watch accuracy of travel time can not calibrated to achieve or maintain
Why? Travel time because of mechanical watches is constantly changing, the tightness of winding states in a fixed position, and temperature conditions it can temporarily accurate, the relative change will be another situation. In other words, even to watch a second correction was not bad, it will not be maintained, the accuracy will always be fluctuations in the transient and changing. Moreover, the accuracy of the watch there are many other factors, we see real go and watch the error is the average error per unit time.
* Watch the full string state winding precision of the best travel time
To get accurate time and watch their own, must take as much as possible on the full winding, automatic watches, which is more important. Tighten the automatic winding watches the extent and wearing time, wearing a sport is directly related to the prerequisite is to ensure that a sufficient amount of exercise.
* Under the watch of different locations have different travel time accuracy
This is called the watch position error, the better the watch factory in three different temperatures and tested under five directions, five positions are: surface (dial up), facing down, the next (3 under) to the left (under 12), the last (9 under), and only the right position (6 under) is not commonly used (unless you put the table into the palm of the hand or the right hand side). According to statistics, most people watch in one day using the time for the surface location of about 35% to 30% left to under 25%, 10% of other locations, so the watch in different locations using different precision error of travel time can be tendency to correct the speed of the watch.
* To be observed before the test, and then recorded
Testing is simple, give the table full of winding, and then aligned by a standard test of time watch hours, minutes and seconds, so that they sync, the first place position in the real plane to go after 24 hours compared with standard time errors and recorded. Repeat the process followed, respectively, under the surface of the watch, the next, to the left, to go on the actual location of the error test, and recorded.
For example: static test results are: the surface of +20 sec / day, area under the +20 seconds / day, the next -5 seconds / day, the left +25 seconds / day, the last 10 sec / day, then the actual travel time to wear the watch error +15 seconds / day.
* Watches the evening off select watches placed to correct the error of orientation
Take the example above circumstances, it is clear exemplar of the night hands down should be placed in order to help reduce the accumulated error of travel time watch. Of errors only on the watch and the features of their watches have a precise understanding of the error, it can better serve you.
A friend and I recently described, and said he was flying, the watch glass actually gone unexplained, but also an expensive IWC watches. This situation may be considered a case, because most people probably have not encountered before, not even heard of, but it really is possible.
Say this is a pressure problem. We know the altitude there is a relationship with the atmospheric pressure, the higher the altitude the lower the atmospheric pressure, atmospheric pressure decreases with height increase, to a certain extent, every increase of 12 meters above sea level, atmospheric pressure decreases 1mmHg.
Now airliner altitude of about 10,000 meters or so in order to protect the safety of passengers and flight comfort, the cabin pressure must be given, even if so, when the aircraft up or down, they still have ear pain, ear plug, even eye pain, headache response occurred.
This situation is due to air pressure inside and outside the body is different, reflecting the sensitive eardrums and eyeballs, I was like, chewing and mouth do not work, only the yawning better to point. Qualified waterproof watch, and certainly a good seal, the watch to resist the pressure of the outside world, there are two cases: compression and decompression. Pressure when the glass or table to watch the more pressure will be more compact; and experience decompression is not, it is a similar negative pressure vacuum, glass and table to be the outward expansion of the force.
Waterproof watch doing experiments, but also a way to do negative pressure to the pressure tank watches are sealed to reduce the atmospheric pressure to 400mmHg, very powerful, air space watches, including watches, mountain use, need to specialize in The experiment failed watches, watch the glass will burst out of case. Now watch waterproof test, the devices are basically using the pressure pump, including decompression, the experimental equivalent of the pressure of the actual pressure storage tanks, pressurized aircraft cabin is also true, but it is not that big pressure. Therefore, once an airplane is equal to your watch in a way, made one such experiment.
If civil aircraft in the air, a sudden decompression, were about to faint on the spot never in the past, there will be life-threatening; watch after a sudden decompression in the compression, seal is not a good watch (except for completely waterproof), but also can watch glass to the top out, this in depth in diving watches, but also meet the tests.
Not waterproof watch, do not have that problem, because the watch seals bad, there will be little gap, the pressure inside and outside the watch is always the same. Watch out flying glass, the watch is because of pressure between the inside and the cabin pressure difference, and the table with the glass and the case is not good due to fastness. The watch is dead, it can not like people do, also know at this time should be open “mouth.”
Watch glass is thin, between the glass and nylon case seal watch, need extra care, the more thin glass, the combination of fastness with the worse case, the possibility of flying glass, the greater the lost.
My advice is: do the aircraft may wish to first watch off, wrapped into the bag, the best and most reliable way is to also pull out the head table, but this may cause a temporary stop watch to go, until the next the plane under the watch after the first observation of any abnormal, if the glass really falls off, you will not be lost, not difficult to install on a brand-name watches, sapphire glass is also very expensive. Glass is lost, if not in time, will also lead to damage Biaozhen and dial, this situation appears to be related, went to big trouble.
Anti-meter vs water table
A watch if there is water resistant but did not identify the exact depth of the note, this watch is called the anti-water meter, it is intended that this watch can resist water spill occasional attacks.
Please do not use this form dipped in the water. Generally indicate water depth of watches, its water resistance and is proportional to the depth of water depth.
There are many ways to make your watch water resistant features. All the watches can be sealed by rubber gaskets watch back cover office water resistant way to achieve the purpose. If you watch the back cover is fixed with screws, then it has a better water resistance. Many tables crown is screw fixed, as is adding more resistance coefficient of water.
Help
* Coefficient of water resistant 30m. Such watches can resist the invasion of rain, but you can not wear when swimming or diving.
* Coefficient of water resistant 50m. Such watches can be swimming in shallow water in the shower or wear.
* Coefficient of water resistant 100m. Such watches can be worn while swimming or diving.
* Coefficient of water resistant 150m. Such watches can be worn in the diving.
* Coefficient of water resistant 200m. Such watches can be worn in the Skin Diving.
* Diving tables 150m. Such watches meet ISO standards, can be worn in deep diving.
* Diving Table 200m. Such watches meet ISO standards, can be worn in deep diving.
Although automatic mechanical watches without batteries, but some simple maintenance is very necessary. This will extend the service life and good movement watches state very helpful.
The operating principles of automatic winding watch is the arm swing will lead to movement round and round, so as to achieve the purpose of automatic winding. You touch of the arm every day, it will record accurate time for you.
If you wear every day, automatic watches, the best maintenance is about every two weeks tight winding, to ensure its smooth functioning of the normal gear. Gently rotating the crown (which can also adjust the time with date) until you can feel the original pressing slightly.
If you are not automatically watch every day wear, you should ensure that at least winding once every two weeks to ensure the continued operation of watches, that is, the internal mechanism to ensure regular and accurate operation.
Best time in the same day to you winding mechanical watches. This approach is very useful mechanism inside. If You want to form a rule, it recommended that you get up every morning after the winding table for your love.
Do not set the date and the week at night index (if your watch has these functions). Date and week control mechanisms are active at night gap, if you change the settings at this time, it is bound to upset the established rules.
When you continue to arm during sports activities (such as tennis, baseball, golf, etc.), they suggest you do not wear automatic tables, because of persistent arm swing will destroy the watch movement.
sports watch Waterproof
Watch in waterproof performance can be divided into diving watch, waterproof watch and non-waterproof watch. Please purchase and use of pre-determine the performance of your waterproof watch.
Waterproof watch on the table glass, rear cover, table, etc. of the waterproof rubber ring to achieve the appropriate standards, are usually classified according to their grade 30 meters, 50 meters, 100 meters, 200 meters, 300 meters.
30 meters water-proof means that the watch can withstand the pressure when the water depth of 30 meters and will not leak, the pressure of 30 meters water depth shall be 3 “atmosphere” or called 3 bar (bar). It can be in the diving, rain, car washing baths, the environment and will not wear leakage, do not press movement is transferred in the water.
Water watches are not in any contact with hot water, water vapor (such as hot water washing bath, sauna, etc.), because the watch waterproof apron will be affected by temperature, thermal expansion and contraction gaps appear to accelerate aging. Large temperature changes or the use of environment, so that the table in the air moisture condensation, causing water and mist condensation occur within the table. If this happens, the watch as soon as possible to professional maintenance department cleaning and maintenance.
Watches linking to remain in the normal position, screw head should be tightened up his head at water or wet dirt, you should clean it and then pull out the SLIDE to prevent the water into the ashes.
Watch waterproof apron and tables to (inclusive of water circle) based on usage should be changed regularly.
Identification of brand name watches are generally identify movement and appearance of identification, the following description on these two watches Identification of common sense
Identification of movement
From the movement point of view, authentic watches the movement of thallium within the splint, or put a corresponding mark on the signs marked words; movement in the case of a solid component; movement cleaning. Imitation watch or pendulum movement of the splint of thallium were no signs mark the words, or trademark sign writing rough, fuzzy, skew, or simply with a small copper paste; movement inside the dirty, some movement of copper within the crumbs, hair , fingerprints and so on. Where imports of Swiss watches, which uses the movement must be manufactured in Switzerland; where imports of Japanese watches, which uses the movement must be produced in Japan.
Watches look Identification
Now watch the appearance of components in the proportion of high prices. Such as the French production of “Cartier” watch, price of 3.52 million yuan. Setting a natural diamond, 36 carats, 60,000 yuan per carat basis, the light on the more than 200 million diamonds coordinates. Therefore, the appearance of the quality of components should be reproducible, have the following main aspects:
1, Table glass, the quality of identification: Table currently in use, as described above there are three kinds of glass: plexiglass, ordinary quartz glass, sapphire crystal glass. Confusing and difficult to distinguish the quartz glass and sapphire crystal glass. Both in terms of quality and price are very different. Sapphire crystal glass was once known as the “never wear the glass,” which cost about a few times ordinary quartz glass, so only in the middle of high-end watches with sapphire crystal glass. Ordinary quartz glass and sapphire crystal glass in the absence of detection instrument can be used when a simple method to determine: a drop of water can be used on the glass flat on the table, and then put them to enact, where the water was not dispersed as small ball sapphire crystal glass.
2, case and back cover. Where the original watch, especially the male form, must be the case after the stamps have a lot of English letters, specify brand name watches, production country, all-steel or semi-steel waterproof, anti-magnetic, shock or vibration device name (see the following common Watch English letters mark the appearance), and engraving a watch brands exclusive trademark logo. In addition, also engraved with the figures used to indicate the watch movement number and shell numbers. Imitation watches stamped with the letters engraved pattern and most of some very thick vague, does not indicate chassis number and movement number.

From King Kong to the gold-plated, silver-plated to the present gold, platinum, watches the material is also changing. Platinum is the watch once the most popular color, but this year, the latest trend trend is Shaodai pink rose gold. A variety of luxury watches, diamonds have become indispensable decorations, inlaid less only in the scale there are 12 diamonds, and more are on the surface outside the ring onto the root surface or even the whole effect will be flashing bright light. Strap material is also multi-up, such as rubber, silk, according to the East to sell a commercial watch more than 10 years of sales presentations, tables are now a lot of women were using high-grade silk strap, because the ribbon is most compatible with the evening wear. However, the traditional leather strap not backward, but they have become more flowers in the hasp on the leather strap end of the first — butterfly buckle, not only beautiful, but also to extend the strap life.
Whether it is also what is the calendar quartz watches and watch dial needles restricted availability of taboos against going to buy a watch a friend have a few suggestions to maintain the accuracy of mechanical watches, take the easy way to be demolished when the double-disc methods and tools to balance the fat clocks the way of torque pulley and sesame-chain how to fix refining its stand wrist watch case and the scratch? Mechanical watches, both dial with a needle and needle body. Dial needle is used to adjust the time or date when the watch is running must also be a pointer to accurately drive the direction of time.
In the needle by rotating the table to call time will feel there is a tightness and demands are not too tight nor too loose. Most of the new watch, you may feel a bit tight for some, but old watches (especially mechanical watches), are often less stringent.
Watch dial inside the needle and body with a needle, there is mainly a gear, is usually sub-round, or has been called “a small center” wheel, specifically to look at watches, calculating a center of transmission or transmission of the eccentric. This gear will be set in the center axle, the center axle of the tilt angle will be along the shoot, while the small center at the corresponding positions on the gun barrel on each side of a groove, that is, between them is too flexible to win by matching. Off-center drive watches calculating, is divided into round pieces on the wheel spokes and sub-axle gear with flexible tubes. (See photo)
With the tightness of this place, determine the allocation of needle elastic sense of time, in this position most prone to wear and tear. In particular, mechanical watches, often need to dial needles, or proof-reading the calendar, frequent dial-pin sub-round of results will increase wear and tear.
If the dial needle felt very loose, it would most likely occur watches “non-needle” failures. Watch the so-called “non-needle” refers to the watch the second hand go, but when the minute hand does not go or not go away when you walk, or “lose turn” of the. In particular, with a calendar and week calendar watches, in the dancing calendar day, when calculating the “load” will gradually become larger, if the allocation of pine needles, then it is more likely a “lose turn”, the performance of the walk slowly, or simply watch, the minute hand does not move.
Old mechanical watches, the place most likely to go wrong, mainly in the long-term use of the wear and tear. When repairs are to re-center groove in the small parts do squeeze, migraine center to trim round piece, the goal is to restore them to an appropriate flexibility to cope with demand.
However, the dial needle can not be too tight, if the dial needles feeling very tight and the watch will have the following bad effects: (1) directly on the teeth of the Department of dial needles are hurt easily lead to lying round of straight teeth, smaller than a round of , cross-Wheel cutter and shaft wear and tear, or even result in a broken tooth tip, which is the most prone to mechanical failure of parts of watches; (2) will result in an increase in errors watches, the provision of needle tight situation, when the dial needle great moment will be attached to the drive wheel system, if a clockwise dial needles, watches the second hand soon be gone too fast, rapid; and counter-clockwise dial needles, the second hand will stop and walk, or walk backwards (in the watch without removing the only second circumstances). If the watch suddenly found himself feeling of dial needles exception difficult, it is recommended, do not hard-allocated, and this need to the table promptly sent to the watch repair shop to do a repair, so as not to damage parts.
Case or tables to bring more local deep scratches, repairs need to do first before the local treatment to see if location, such as the case of the shell-side, or even possible to spend a small fine FILE, more is the oil stone , then under the magnifying glass, carefully put deep scratches boring flat
Two days ago, I gave a friend deal with a Cartier watch, the former case was severely scratched circle, but also a deep scratch, for the first lines of this drawing sand circles, repairs on the fact easy, tool only need Hone, various size of the sandpaper, polishing cloth wheel is enough to use.
Deep scratches, they should focus on local oil stone before polishing to do. This needs to under the magnifying glass for the purpose of evenly polished to a scratch, when the scratches have been refining its stand polished basic, select the appropriate size sandpaper, along the original lines to pull sand mill, usually the lines are is a radial dial-centered, so this is a carefully live, and a little bit, the grinding out results will be real good. The proposed use sandpaper with the kind of the jewelry industry, preferably imported, such as Germany Warriors brand of water sandpaper.
Hand-held tools also have stress, it is recommended the use of surgery to stop bleeding on the pliers, just take a small piece of sandpaper, to stop bleeding by clamping tightly folded parallel to the original lines doing pull sand, sapphire glass, relatively hard, you can not consider it, but watch is a stainless steel shell, and operations must pay attention not to draw rubs up against it, and if necessary, can be covered by adhesive tape to live it.
Technical aspects, is that we must all pull sand lines should go has always been, and are based on dial center in, and the radial.
All watch case and strap scratches the above, in order to get rid of it or to watch looks to be a renovation of beauty, can refer to using this method. Linear shape of lines easier to carry, if the lines are concentric Park, it should still be done using electric machinery class.
Own use sandpaper to scratch the above case strap trim, not a difficult task, as long as the steady hand to be able to do a good job carefully; but for the surface polishing process, it must use the cloth wheel polishing machines, and ordinary people do can not.
For there have pull sand polishing process case and strap, trimming should do first pull when the sand grinding, and polishing do is just need to have a good finishing position to cover the sand drawing, the simple can use tape, formal to do some of the metal template, and also be used to cover the time polishing.
