Is it okay to wear it in high-temperature environments such as bathing, hot springs, saunas, or bathrooms?
No matter how many meters are marked, any of the previous waterproof watches cannot be used in hot water (>40C°).
There are two reasons: 1. The permeability of water molecules is greatly enhanced when the temperature increases and all waterproof watches are designed based on cold water.
2. According to thermal expansion and contraction, some watch components will expand to varying degrees under hot water conditions, increasing possible gaps. Therefore, the eye cannot be exposed to hot water. Otherwise, it will cause waterproof failure.
Why not prevent hot water?
①The waterproof performance of the watch has requirements on the temperature. The rapid change of the temperature difference between the hot and cold of the eye may cause the waterproof watch to generate water vapor.
② No matter how strong the waterproof watch is, it also needs careful care. Any waterproof watch will decline in waterproof performance due to the aging of the waterproof ring or accidental impact.
③ Therefore, it is best not to wear a watch when taking a hot bath or sauna to avoid gaps in the waterproof ring due to thermal expansion and contraction, which will accelerate the aging of the waterproof ring, thereby affecting the waterproof effect.
④ Pay special attention to the fact that the crown and operation buttons cannot be adjusted in the water, and the crown should be pressed tightly before touching the water.
How much error is standard for a mechanical watch?
The instantaneous error range of the travel time of qualified mechanical watch products stipulated by the state is -70~+135 seconds per 24 hours.
How long does it take to wind up?
Usually, about a month is enough because after the gears and parts of the mechanical watch are run in and lubricated, the energy consumption will be less, and the energy stored in daily wear is enough to maintain the regular operation.
