The dial, hands, and crystal show no particularly noticeable scratches, dirt, or abrasions. The watch has not been polished in order to preserve its original condition.
It is in excellent overall condition.

Within its classic approximately 32.5 mm case, multiple elements—including a micro-rotor, moon phase, date, and Skeleton Dial—are brought together. The 18K yellow-gold coin-edge detailing adds dimensionality, creating a design that rewards appreciation not only from the front but in every detail.

This example is Ref.151.11.663, with an 18K yellow-gold case and a micro-rotor Automatic movement. It is fitted with an original Universal Gold-Plated Buckle and an Aftermarket Strap.

Although its approximately 32.5 mm size is compact, the Skeleton Dial and coin-edge detailing provide ample visual interest and a strong presence on the wrist. Its restrained size also makes this 18K yellow-gold timepiece especially easy to wear in a classic style.
