The variety with rectilinear black and white parallel stripes is part of the agate family; whereas the fully black type is know as Black Onyx. A gemstone able to deflect and channel harmful energy towards the Earth, it provides stability. For this reason, Black Onyx is considered a stone of protection against negative thoughts, as well being the stone of equilibrium and inspiration. POWER RESERVE Circa 48 hours.

This is indicated utilizing a newly designed differential power reserve system, with a red line on a moving disc placed between 10 and 11 o’clock.

BARREL PAWL WITH PROGRESSIVE RECOIL This device permits an appreciable winding gain (circa 20 %), especially during the start of winding. It also aids in the even distribution of the mainspring’s internal tension.
