Because no matter how many meters above water depth, can not steam sauna, may know the time in the appearance will not have any questions
Question, in fact, the movement has been violated. Because the appearance of the watch is composed of different coefficients of expansion of the composition, if the table off
Wear the ambient temperature is greater than or equal to 50 degrees, the table will have a pressure difference, under pressure, the table will be the air to
Outer run, when the temperature difference is restored, the outside air ran back to the table. The temperature in the steam bath is much higher than the standard in the table
The air will run out of time when the humidity is higher than the standard air, some time does not necessarily appear immediately hydrometer, but when the sudden low temperature
The temperature in the table above the standard air will condense on the glass, forming water droplets or fog, and the heat of the vapor will speed up the waterproof plastic
Aging circle, can not be normal protection of the movement.
