Clubmaster Sport Acetate Black Chrono NATO Strap Watch

The Watch
This unisex Briston timepiece delivers a boldly sporty design - perfect for timing your personal bests on the track or keeping pace on a cross-country run. Powered by a 5-hand Japanese Miyota OS21 quartz movement, it displays hours, minutes, seconds, a date window, and a chronograph with 60-minute and 24-hour counters. The cushion-shaped case remains Briston's iconic hallmark, adding masculinity and ruggedness to your wrist. At 42 mm wide and 11.90 mm thick, it's built for adventure. A slightly domed mineral crystal protects the dial, and the screw-down case back is engraved with the brand's coat of arms - a nod to its British heritage.

The Dial
The dial on this model is round and black. Its opening measures 32.5 mm. It houses five hands: two black ones for the counters and three white ones for hours, minutes, and seconds. The white hands are made of luminescent rhodium, ensuring maximum readability even in low-light conditions. Complemented by grey baton-style hour markers, the dial remains highly legible. It features two counters: the one at 3 o'clock is the 24-hour counter, while the one at 9 o'clock is the 60-minute counter. A black tachymeter (a measuring instrument used to calculate the speed of a moving object) is also present on a bezel ring inside the dial. At 6 o'clock sits a date window.

The Strap
This model features a Sport NATO strap in black nylon canvas, 20 mm wide. It is interchangeable and secures with a silver-toned pin buckle. The strap length is 280 mm. Designed to handle water contact, this strap is rated to 100 m - meaning it can accompany you during active swimming, though it is not suited for scuba diving.

The Movement
This watch houses a Japanese Miyota OS21 quartz movement. This caliber displays hours, minutes, and the date. The 60-minute counter sits at 9 o'clock, the 24-hour counter at 3 o'clock, and the date window at 6 o'clock. A standard battery lasts approximately 3 years.

Water Resistance
This model offers 10 atmospheres of water resistance - that's 100 meters. We're talking a genuinely water-resistant watch! This fun, stylish timepiece is ready to jump into aquatic adventures alongside you. From puddles to the pool, it handles showers, baths, and active swimming without breaking a sweat. That said, our Ocarat watchmaking experts want to make it clear: despite its water resistance, this model is not suitable for diving (professional or recreational) and should be kept away from high-pressure cleaning equipment. We also recommend avoiding crown or pusher operation while submerged.
