5980/60G – Nautilus

Automatic winding mechanisms

The Nautilus self-winding chronograph with flyback function is released in a new version in white gold with an opal dial in blue-gray color. The leather strap made of calfskin, stylized as denim, perfectly harmonizes with the refined shade of the dial. It is decorated with contrasting white stitching and is complemented by a Nautilus folding clasp in white gold.

The case and bezel attract attention by alternating polished and satin surfaces.

The chronograph indicators are housed in a single large counter with three concentric scales at 6 o’clock, which is distinguished by its original design and good readability. The chronograph’s central second hand can also function as a continuously active second hand.
