The Watch
This model may seem understated at first glance, but its vintage aesthetic and "tortoiseshell" case give it a truly original character - a perfect blend of modernity and tradition.
The case is crafted in tortoiseshell cellulose acetate, evoking a lush natural world. It is manufactured in Italy for the finest quality. The lugs, pushers, bezel, screw-down caseback, buckle, and keepers are in polished 316L stainless steel, prized for its durability and many advantages. The crown is engraved with the Briston coat of arms. The case diameter is 40.00 mm with a thickness of 11.70 mm. This case houses a Miyota OS21 movement delivering hours, minutes, seconds, date, and chronograph functions including a 60-minute counter, seconds hand, and 24-hour display.
The Dial
The upper dial of this watch is silver-white, topped with a domed mineral crystal 2.3 mm thick. The sub-dial is black, making the indices and numerals stand out with clarity and precision. The "baton" hour and minute hands are in rhodium filled with white. The chronograph and counter hands are black. The 60-minute counter is positioned at 9 o'clock, the 24-hour counter is positioned at 3 o'clock, and the date is located at 6 o'clock. This refined dial evokes both a calm, restful atmosphere by the fireside and an adventurous world where only your instincts will keep you alive.
The Movement
This watch houses a Miyota OS21 Japanese quartz movement. This caliber displays hours, minutes, and date. At the heart of this movement, the 60-minute counter is positioned at 9 o'clock, the 24-hour counter is positioned at 3 o'clock, and the date is located at 6 o'clock.
The Strap
The strap is a superb nato from Briston in black nylon. It is interchangeable and water-resistant. It measures 245 mm with a lug width of 20 mm. It fastens with a classic ardillon buckle in rose gold PVD.
Water Resistance
This model offers water resistance of 10 atmospheres, or 100 meters - a truly water-resistant timepiece! With its sporty character, it's ready to dive into aquatic adventures right alongside you. From puddles to the pool, this watch handles swimming without complaint. Showers, baths, and laps in the pool are no problem. That said, our Ocarat watchmaking experts want you to know that this model - while water-resistant - is not suitable for diving (professional or recreational) and should be kept away from high-pressure cleaning equipment. We also recommend keeping the crown and pushers clear of water during immersion.
