The Quinting watches claim to be the worlds first transparent watches. This transparent watch is quite a mystery since there appears to be no visible means of a movement to drive the hands, very intriguing and clever.
The quartz movement is hidden inside the case around the transparent dial. The hands appear to operate with a mind of their own, but they are actually connected to the movement motors by a series of sapphire crystal discs.
Omega did the world’s first transparent watch by the concept of quartz disks back in 1981 with the La Magique
Thats interesting thanks for pointing that out.
