The movement is powered by a battery that needs to be changed, depending on the type of movement, once every 3 to 5 years. In some watches, a dead battery is indicated by the movement of the second hand at longer intervals. It is a good idea to replace the dead battery in the watch as soon as possible.
If you do not have a watch for a demanding environment, then avoid extreme temperatures. The normal operating temperature range of the watch is from 5 to 35˚C. Temperatures above 50˚C or below -10˚C may cause the watch to lag or shorten battery life. The operation of the watch is adjusted by returning it to normal temperature. Never expose the watch to sudden temperature changes. Such a jump into the water with a hot watch from the sun will definitely not benefit them.
The screw crown must always be fully tightened, the other control elements must be in the basic position. Never use the watch while bathing in hot water. A loss of waterproofness can occur when a watch heated by the sun cools down rapidly in cold water (due to the different expansion of different materials).A steel strap should receive the same care as a case. If you have a watch with a leather strap, we have some tips and advice on how to properly care for the leather strap.
Also, don't forget to take your watch to a watchmaker once every two to three years for resealing, battery replacement and general inspection. This will extend their lifespan and you can be sure of their waterproofness.
