The Watch
On a trip through Denali National Park, across the sweeping plains of Alaska, you witnessed something remarkable: the rugged simplicity of life lived on its own terms. Hand-built cabins, a spirit of warmth and community - worlds away from the noise of city life. Back home, that feeling stayed with you. This Briston is designed to bring it back, every time you glance at your wrist.
This unisex watch runs on a Miyota OS21 Japanese quartz movement, offering hours, minutes, chronograph with 60-minute counter, 24-hour display, and date. The cushion-shaped case (dial opening 32.5 mm, 42 mm × 42 mm footprint, 11.90 mm thick) is crafted in tortoiseshell cellulose acetate for a vintage-inspired look. It is topped with a slightly domed mineral crystal for an original, sporty feel. The caseback is screwed down. The brand's coat of arms is engraved on the 316L stainless steel crown, fitted with rubber ring inserts. The bezel is also in 316L steel. With its colors, design, and materials, Briston delivers the perfect companion for every situation, every challenge, every outfit - evening, sport, office, business lunch, or romantic dinner: nothing stops you from wearing it.
The Dial
This round model features a grey sunray dial for a traditional, elegant finish. It houses two grey hands and a white chronograph seconds hand (with a red tip for a touch of motorsport flair). The hour and minute hands are treated with a luminescent coating for easy reading in the dark. The dial is fitted with silver baton indices to mark the hours, also treated with a luminescent material for precise legibility in low-light conditions. A white tachymeter (a measuring instrument used to calculate the speed of a moving object) runs along the black outer ring of the dial. The date sits in a window at 6 o'clock, the counter at 3 o'clock displays the time in 24-hour format, and the one at 9 o'clock is a 60-minute counter dedicated to the chronograph function.
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. A standard battery lasts approximately 3 years.
The Strap
The watch comes with an interchangeable grey canvas nato strap fastened by a silver ardillon buckle. The strap length is 235 mm and the lug width is 20 mm.
Water Resistance
With 100-meter water resistance - 10 ATM in the language of watchmaking - this bold timepiece holds its own at galas and in the water alike. Wear it in the shower, the bath, or the pool (even during an intense swim). That said, our team of watch experts wants to be clear: this model is not designed for scuba diving, freediving, or use with high-pressure washers. The rule is simple: showers, baths, and swimming only - and keep the crown and pushers away from water.
