The Watch
Crafted in Italy, the tortoiseshell cellulose acetate case measures 40.00 mm in diameter and 11.70 mm in thickness, hand-polished with a satin finish.
The lugs, crown, bezel, screw-back, buckle, and loops are stainless steel with a yellow gold PVD treatment. The crown is engraved with the Briston crest.
The dial is green with a sunray finish, topped by a domed mineral crystal 2.3 mm thick. Arabic numerals and indexes are white. The hour and minute hands are rhodium-treated with yellow gold PVD and are luminescent. The white lacquered seconds hand activates in chronograph mode only. The dial features a 60-minute chronograph counter at 9 o'clock and a 24-hour display at 3 o'clock. The date is shown in a window at 6 o'clock.
The NATO strap is green nylon, water-resistant, and interchangeable. Lug width: 20 mm.
This watch is water-resistant to 10 ATM (100 meters). Not designed for scuba diving, but ideal for swimming.
The Movement
This watch houses a Miyota OS21 Japanese movement. This quartz caliber displays hours, minutes, and the date. At the heart of this movement, the 60-minute counter is positioned at 9 o'clock, the 24-hour counter at 3 o'clock, and the date at 6 o'clock.
