Object description

Case and Dial Design

The timepiece is constructed with a two-body, solid, polished platinum case characterized by its concave lugs. The watch utilizes sapphire crystals and a transparent back secured by six screws to allow visibility of the internal mechanics. The watch measures 38 mm in diameter and 11 mm in thickness.

The dial is an off-center design composed of guilloche silver featuring painted radial Arabic numerals. This assembly includes a subsidiary seconds dial and is secured to a matte 18K white gold plate using three screws. The dial layout incorporates a sector for the 120-hour power reserve indication and a prominent aperture for the large double-digit date, complemented by blued steel hands.

Movement and Escapement
