Grabbing and twisting the smallest of watch crowns can be difficult when your watch is in need of winding. Bergeon’s line of watch crown winders makes it easier than ever to manually wind your watch.
These crown winding tools come in four different sizes to cover crown sizes from 2.00mm to 7.00mm. With a push of the plunger a strong spring inside the tool opens the jaws to fit around your crown and grab it firmly, giving you a large handle to use to wind the watch.
Screwing and unscrewing the plunger opens and closes the jaws, so if it seems like the tool doesn’t fit, try to unscrew the plunger to open the jaws wider.
