The Claude Bernard Slim Line 80501 3 NIN is an incredibly stylish Swiss Made watch. It has a moonphase complication at 6 o'clock where you'll see an aperture in the dial which shows the actual position of the moon (so it's not a day/night indicator). Alongside this feature, the watch also has a date complication at 3 o'clock. The watch is powered by the Cal. 805. This is a Swiss Made automatic (mechanical) movement that can be powered by movement (through the rotor) or alternatively by hand via the crown.

The watch itself is 42mm so it has a beautiful wrist presence, but it's not overly large, as the watch is stunningly elegant and beautiful. The fine leather strap also has a deployant clasp, for added comfort. 

The Claude Bernard Slim Line 80501 3 NIN is beautiful, has a lot of horological merit and is a joy to wear. The deep black dial matches incredibly well with the steel hands and accents on the watch. Pure harmony and style!
