Regardless of whether the watch is waterproof, the temperature it can withstand must not exceed 40°C.
Any watch is not suitable for wearing in warm water or the bathroom, even if your watch is waterproof, because its sealing ring is rubber, the temperature is easy to age, and the surrounding steam molecules are small, it is easy to penetrate the case, causing internal mechanical damage.
We also need to pay attention to the season when using the watch. In general, try not to use the watch frequently in the summer. Sweat from your hands will corrode the outer shell. Although the corrosion resistance of the all-steel table is better, the semi-steel table is basically made of copper, and it is easy to corroded by long-term contact with sweat. Therefore, it is necessary to often wipe sweat with a soft cloth or pad a plastic watch frame to prevent the watch from being corroded by sweat.
