Watches, in fact, are a discipline that is actually very interesting, but it takes a lot of effort to really master it. So what are some watch general knowledge that even frequent watch wearers don't know?

1. How to quickly distinguish a quartz watch from a mechanical one

Observe the movement of the second hand on the dial: if both have a second hand,TUDOR Black Bay M7941A1A0RU-0003 the one that clearly jumps from second to second is a quartz watch, while the second hand of a mechanical watch jumps continuously and appears to be slowly gliding across the dial.

Of course there are exceptions, such as Jaeger-LeCoultre's spherical physical chronometer true seconds, a mechanical watch that has an internal jumping seconds device mechanism independent of the seconds wheel, making it have the same movement as a quartz movement watch.

2. Can automatic mechanical watches be manually wound

The manual winding of an automatic watch will not have any effect on it, after all, this part of the automatic winding is an additional mechanism in itself. Depending on the intensity of his activity,TUDOR Ranger M79950-0001 the wearer will decide whether he needs to manually wind the watch first when using it, and then store the power to the full through automatic winding.

In the case of a self-winding watch that has been stopped, it is necessary to manually wind the watch for a few revolutions until the hands begin to move. This is in order to let the clockwork quickly into the state of even release of power, after all, the watch because of the lack of power to stop, just by automatic winding may not be able to quickly achieve the effect of use.

3. What kind of steel is the "steel" used to make the case?

The term "steel" is a common name for high-precision steel that has been specially forged, and there is no academic or engineering term for it. The "steel" used for watch cases, bracelets, and crowns generally refers to 316L steel, which is a common austenitic stainless steel that is very resistant to corrosion, has a very good texture, and will not adversely affect human skin. And 904L steel is a kind of super heat-resistant stainless steel alloy, containing chromium, nickel, etc., its corrosion resistance can almost be comparable with the precious metal materials, manufacturing cost is much higher than the 316L steel, now only Rolex widely and systematically use this material in the case, bracelet, and the production of crown.

4. How many turns does the crown have to make before a hand-wound watch is fully wound?

Generally speaking, for watches with a power reserve of 48 hours, the number of winding revolutions is in the range of 20 to 30. Other power reserves can basically be calculated according to this ratio, but it is not a certainty. When the crown turns to a number close to the upper limit, pay attention to the feeling in your hand, if you feel a little tight, the crown rotation is not as smooth as before, you can stop. In short, for the sake of the watch's lifespan, don't go to 100% every time you wind up the watch, it's better to leave some leeway.

5. Self-produced movement is the best!

Brand watches self-produced movement is the benefit of their own can control the quality of the product, and then through publicity, to the brand set up a picture of the "high" image, many people's consumption concept, spend so much money must buy more upscale, more cattle self-produced movement.

But in fact, the self-produced movement is not necessarily equal to a good movement. Good movement research and development, design, production needs time precipitation, accumulation of experience, and not a very short period of time by smashing money into the equipment, please senior watchmaker can be completed, even if a micron of inaccuracy, may affect the watch time.

The cost of the general ETA movement in thousands of dollars is also generally shared by the big names, and decades are calm. In fact, the self-produced movement needs to yield and time accumulation, in order to gradually mature.

6. Is the ranking of the top ten international watches unreasonable?

Although the "Top 10 Watches" cannot be said to be completely unreasonable, it has certain limitations and cannot be regarded as a golden rule. 10 brands of watches have different positioning, different styles, different strengths, some are good at movement polishing, some are more accurate and durable, and some are very good at jewelry inlay. There is no standard, not to mention the fact that all brands are not static in their development over the years.

7. Why do watches with luminescent function yellow over time?

Generally speaking, the scales of watches with a history of more than ten years will show the phenomenon of yellowing, especially in the case of watches with luminescent function. According to statistics, the average time of this phenomenon is 12.5 years, which means that the luminous appears to be aging and gradually loses its luminous effect, and this phenomenon occurs in many antique watches.

Watches with luminescence generally use luminescent material as "tritium", which is a kind of material that can emit light on its own without absorbing light, and the luminous intensity is much better than the traditional luminescent material, coupled with the small radiation, so it has become the most popular material for luminescent watches. However, tritium can only maintain the brightness for about ten years, and after ten years, it will gradually begin to age and yellow.
