Object description

Case and Dial Design

The watch is housed in a solid three-body case constructed from 18K white gold. The exterior features a polished and brushed finish, designed with straight lugs and a stepped bezel. The case is equipped with sapphire crystals on both the front and the transparent exhibition back, allowing a view of the internal mechanism.

The silver dial is decorated with guilloché patterns and features an outer satiné silver reserve. Applied black Roman numerals mark the hours. The dial layout includes a 30-minute chronograph register positioned at 3 o'clock, a subsidiary seconds dial at 9 o'clock, and an aperture at 6 o'clock revealing the tourbillon regulator beneath a polished steel bridge. The time is indicated by white gold feuille-skeleton hands.
