HOW TO WIND A WATCH :
Important to know about automatic watches for FIRST-TIME OWNERS
Do automatic watches need to be manually wound?
Yes, they do.
When you first get an automatic watch, the spring is completely unwound. Moving the watch around will cause the rotor to spin, which in turn will begin winding the mainspring. While this will get the watch running it will not be enough to fully tighten the mainspring which would let you take advantage of the power reserve to its fullest capacity.
It is therefore important to first wind the crown about 30-40 times which is enough to completely wind the mainspring on most watches. Once the mainspring has been fully wound, and the watch is worn on an active wrist, the rotor will do its job by continuously winding the mainspring thereby topping off the watch's power reserve.
How do you wind an automatic Watch?
Clockwise and crown pushed in position (position 0).
A watch is wound via its crown, usually clockwise (Down to Up). Keep the crown in its pushed-in position and wind the crown clockwise. If your watch has a screw-down crown, you first need to unscrew the crown before winding.
Can an automatic watch be overwound?
No. Automatic watches have a mechanism in the movement that disengages the winding gears from the mainspring once it is fully wound.
What is a Power Reserve?
The power reserve is the amount of time it takes for a fully wound watch to unwind when not worn. Most mechanical watches have a power reserve of between 36 and 42 hours. This means that the watch can run for that duration on a full wind. Bonest Gatti’s automatic watches have a 42 hours power reserve.
Date & Time adjustment?
Date : position 1, rotate the crown counter-clockwise (Up to Down)
Time : position 2, rotate the crown counter-clockwise (Up to Down)
