Object description

Case and Dial Design

The watch features a circular case measuring 28 mm in diameter, crafted from a combination of steel and gold. The bezel is fluted, a decorative element that complements the fluted crown positioned at the 3 o'clock mark. The dial is gold-colored and serves as the background for applied diamond indices that denote the hours. The hands are fashioned in a baton style.

Positioned at the 3 o'clock location on the dial is an auxiliary window displaying the date. This aperture is viewed through a Cyclops lens, which is mounted on the external surface of the crystal to provide magnification of the displayed numeral.

Bracelet and Construction

The watch is fitted with an Oyster bracelet, which is designed to match the case in its bi-material construction of steel and gold.

The overall build reflects a construction aimed at maintaining the aesthetic characteristics associated with the Datejust line.

Measurements provided by the auction house indicate a total case width of 33 mm when the crown is included in the dimension, highlighting the compact nature of the case profile despite the presence of the fluted crown mechanism.
