(1) folding table wearing sauna, completely wrong.
Waterproof to a depth at because no matter how many meters can not be sauna, may be known on the appearance of time will not have any problem, in fact, has been against movement. Since the appearance of the watch pieces are from different expansion coefficient of materials, if the folding table wear environment temperature greater than or equal to 50 degrees, the table will have a bad pressure, at atmospheric pressure under the table, the air will be outward run, when the temperature is to restore the bad, the outside air is back to the table. Steam bath temperature higher than the standard large table, where the air will run out when the humidity is higher than standard air, some at the table does not necessarily occur immediately water vapor, but suddenly encountered a low temperature when the temperature is higher than the table standard air condensation on the glass, the formation of water droplets or fog, and steam heat will accelerate the aging of waterproof apron, not the protection of movement.
(2) of the condensation droplets form a mirror to confirm for the sapphire crystal;
This approach is unscientific approach.
Because some mineral glass condensation will also drop, and some on sapphire crystal droplets will disperse, but the degree is the same as anti-wear, table mirror material for which manufacturers will be made clear, and to try not to use water droplets.
(3) quartz watch battery replaced after no longer waterproof, and is not accurate when the go: This opinion is wrong.
Zhongfu the repair of equipment very well, give you replaced the battery in after the major instruments used by professional technicians to re-suppressed, re-waterproof, measurement error Whether or not going at the normal time period. So please at major repair stations must replace the battery.
(4) friction surface, is zoned glass table Antiwear confirmed acts, but we do not recommend customers to experiment with disruptive behavior.
Another high-tech ceramic Although a high degree of anti-wear, but fragile, and afraid of crashing fall.
