Object description

Case and Dial

The timepiece features a circular steel case measuring 43 mm in diameter. The navy blue dial utilizes a combination of applied indices and large Arabic numerals at the 6, 9, and 12 o'clock positions. Both the indices and the hands are treated with a luminescent material to enhance readability. A day-date complication is integrated into the dial at the 3 o'clock position, displaying the day of the week in English and the numerical date.

A rotating bezel surrounds the dial, featuring Arabic numerals and an indexed scale for dive-time tracking. The watch is signed 'BREMONT' on the dial, with the model name 'SUPERMARINE' and depth rating '500m-1840ft' printed below the center pinion. The case is fitted with a blue rubber strap secured by an original buckle clasp.
