4 Watch the “Anti”
At the national standard, magnetic and shockproof performance standards is the “residual effect” to indicate the remaining effect refers to the pre-test and watch the instantaneous difference between the instantaneous detection of deterioration after watch the difference.
Shock: When the watch is accidentally dropped from a height of 1 meter horizontal hardwood surface, the residual effect of quartz less than 2 seconds, the residual effects of mechanical watches no more than 60 seconds.
Magnetically shielded: When the watch occasionally in intensity 4800A / m magnetic field, the residual effect of the quartz watch no more than 1.5 seconds, mechanical male form (movement area of more than 314 mm2) not more than 30 seconds remaining effects, mechanical effects of the female form the remaining less than 45 seconds.
5 Watch by the Secretary in addition to water
Water within the case are not careful, the available granular material called silicone watch with the already water together into a sealed container for several hours, remove the watch, water that is lost. This method is simple and economic life of the meter accuracy and not have any damage. Silica gel after absorbing many times, dried at 120 ℃ for several hours, water absorption capacity of renewable, but also repeated use.
6 watches refurbished by the Secretariat
Watch a lot of channel pattern mask was set aside after the first drop in 12 drops of the table covered with water, then squeeze a little toothpaste obliterated, you can draw lines removed leaving the table kept as new.
7 watch by maintenance of secret
(1) wear watches, the hands sweat on the case of corrosive, steel case because it is nickel-chromium alloy, corrosion resistance better, semi-steel case is copper, long-term contacts with sweat, easy corrosion, should be often with a soft cloth wipe sweat or plastic table mat care, to prevent erosion of their sweat.
(2) Do not open the table cover, so as not to affect the movement of dust into the watch work.
(3) Do not have a watch on the wardrobe mothballs, so as not to form oil deterioration.
(4) Do not watch on the radio, TV, in order to avoid magnetization.
(5) long-term storage does not wear a watch, should be a regular monthly winding, so that parts will not be long at rest, in order to ensure the operation of the printer properties.
