1. mechanical watch repair the most common situation, nothing more than water and crashed. Mechanical table unless marked with waterproof function, you must avoid case into the water, because the water will cause corrosion of mechanical, destructive power is very strong. Together with sweat, dust and other inevitable external factor will become stale, so waterproof ring must be renewed after one year, it is no waterproof function.
2. in addition to waterproof, it should guard against collisions. Under the scope of the economic capacity of, might as well have Liang、sanzhi table replace in everyday life: static when worn mechanical watch, engage in dynamic activities wearing sport watches, so when local conditions will help extend the life of table.
