Object description

Case and Dial Design

The watch features an 18-karat rose gold case with a diameter of 40 millimeters. The design incorporates specific architectural elements, namely sculpted, hollowed lugs and a concave bezel, which contribute to its aesthetic profile. The case is polished to a high finish.

The dial is rendered in an olive green tone and utilizes a sector configuration.
