What are the recommendations when use mechanical watches?
The allowable error range of mechanical watches is ±45 seconds/day. The average error range of the movement certified by the observatory is between -4 seconds/day and +6 seconds/day. The power source of an automatic mechanical watch is the movement of the wearer’s wrist to generate energy to wind the mainspring. A fully wound automatic mechanical watch can run continuously for about 35 hours. If it is guaranteed to be worn normally every day, it can operate for about 15 hours. If the watch is not worn for more than the above time or the swing is insufficient, it will cause the watch to stop. It is recommended that you wind up the watch before wearing it again.
1. Watches with manual winding movements should be wound at the same time every day as much as possible. Make the watch have enough energy to operate in the next 24 hours.
2. The energy of a watch with a self-winding movement comes from the movement of the wearer’s arm. Therefore, manual winding is not required under normal wearing conditions. Only when the wearer’s exercise is not enough to replenish enough energy for the mainspring, manual winding can be used to make up for it. And when winding, the crown rotation is controlled within 30 revolutions.
3. Self-winding watches that have not been worn for more than 40 hours. When you wear it again, turn the crown 30 times to start the drive system of the movement again.
4. In order to prevent moisture from penetrating into the case and maintain the waterproof performance of the watch. Make sure that the crown is locked at all times.
