Object description

Case and External Features

The watch is housed in a cushion-shaped case measuring 44 x 44 mm, utilizing a combination of titanium and stainless steel. The construction includes a polished finish and a screwed-down case back, which features engraving. A key feature is the patented crown security lever, which allows for the watch to be wound even when submerged underwater. The crystal is sapphire and includes a 'cyclops' lens to enhance the visibility of the date aperture.

The timepiece is fitted with a stainless steel link bracelet secured by a deployant clasp. The case back is screwed down to ensure the integrity of the water-resistant construction.

Dial and Hands

The dial is finished in a gray tone, providing a backdrop for the luminous Arabic numerals and indexes that allow for time reading in low-light environments. The layout includes a subsidiary seconds dial positioned at the 9 o'clock mark and an aperture for the date at 3 o'clock. This aperture is magnified by the lens on the crystal.

The time is indicated by luminous steel 'bâton' hands. The aesthetic remains consistent with the military-inspired diver design, maintaining clear legibility and a balance of functional elements throughout the face of the watch.
