The round case of 43mm is in platinum for a chic look. This surrounds an amazing semi-skeleton dial in grey with an authentic design. The main off-centered dial indicates the hours & minutes on a stunning black dial with white roman numerals. The small seconds counter is integrated to the main dial and gives an elegant extension and finish of the dial.
But the main feature is the ruby-link chain on the left to maintain a constant force for almost two days! A part to be a revolutionary function it’s also very beautiful!
The incredible movement is visible from both sides and through the sapphire case-back you can also have a look at the power-reserve indicator of 46-hours.
A genuine black alligator strap will fix this beauty around one lucky wrist!
