Our self winding timepieces are designed to gain power from the natural movements of the wrist on the person who is wearing the watch. Manually winding it every day is unnecessary and you also do not need a battery.
Wind an automatic watch by turning the crown enough to jump start the power source, and then allowing the self winding mechanism to work by simply wearing the timepiece! Winding is also required when the watch gets low on power due to not being used for a period of time.
If you are still unsure of the mechanical winding design, please email us for more details and brief explanation.
For a self-winding watch to function properly, the mainspring must build up a sufficient power reserve. Many people are unaware that a self-winding watch needs to be wound first manually before it will run automatically. This is called the initiation process. Without the initiation process, the watch will never operate properly or consistently.
To initiate the power reserve, the watch must be wound manually. Turn the winding crown at the 3 o’clock position, in a clockwise direction for about 30 revolutions. This start up wind is usually sufficient for most automatic watches.
(Please do not continue to wind your timepiece you feel that the spring is already fully loaded otherwise the clockwork may be damaged)
After completion of the initiation process, the watch will wind itself automatically (rebuilding the power reserve) by means of an oscillation weight that shifts every time the watch’s position is changed by the action of the arm and wrist. Put on your watch and swing your wrist back and forth for approximately 30 seconds to initialize power reserve.
A self-winding watch should be worn at least eight hours a day to maximize the power reserve. If this is not possible, or if the watch has been off the wrist for more than 15-20 hours, the initiation process must be repeated.
ARE ZINVO TIMEPIECES WATER RESISTANT?
All of our pieces are 5ATM Water Resistance. This level of protection will easily withstand splashes or brief immersion in water, or getting caught in the rain. as well as swimming or bathing.
