The Watch
How many shades of green do you know? This one is British Racing Green - a color that speaks to nature, youth, and calm, yet on this watch, it tells a completely different story: the story of a seasoned adventurer who has battled through the harshest trials in jungles teeming with every kind of predator. Pair it with the green NATO canvas strap, and survival just got a little easier. The British Racing Green dial, matched with the khaki strap and tortoiseshell pattern, delivers a So British vintage spirit that's effortlessly elegant - the kind of style that comes with a side of English cool. All you'll need now is the wardrobe and the Indiana Jones one-liners. The watch offers hours, minutes, chronograph with 60-minute counter, 24h time display, and date. The cushion-shaped case (dial opening 32.5mm, 42mm length × 42mm width, 11.90mm thickness) is crafted from cellulose acetate with a vintage tortoiseshell design. A slightly domed mineral crystal tops the case for an original, sporty look. The caseback is screw-down. The brand's crest is engraved on the 316L stainless steel crown, fitted with rubber ring inserts. The bezel is also 316L steel.
The Dial
Round in shape and finished in a sunray green that evokes the wide-open hunting grounds and quintessential British character, it features two gray hands and a white seconds hand dedicated to the chronograph (with a red tip for a subtle sporty, mechanical-on-water feel). The hour and minute hands are treated with a luminescent material, ensuring easy time reading in low-light conditions. The dial is adorned with silver-tone baton indices to mark the hours, also treated with a luminescent material for precise legibility in the dark. A white tachymeter (an instrument that measures 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, while the counter at 3 o'clock displays the time in 24h format and the counter at 9 o'clock is a 60-minute counter dedicated to the chronograph function.
It is worth noting that the sub-dials are black with white indices, reinforcing both legibility and the sporty character of the watch.
A clean, understated dial that lends its wearer a refined elegance - steeped in the timeless charm of the British sporting gentleman.
The Movement
This watch is powered by a Japanese Miyota OS21 quartz movement. This caliber displays hours, minutes, and the date. Within the 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. A standard battery lasts approximately 3 years.
The Strap
The watch comes with an exclusive Briston NATO strap in British Racing Green with a silver-tone pin buckle. The strap length is 235mm with a 20mm lug width.
Water Resistance
This model offers water resistance up to 10 atmospheres, or 100 meters - it's genuinely waterproof. Ready to dive into aquatic adventures with you, it handles everything from puddles to the pool without complaint. Showers, baths, and active swimming? No problem. That said, the Ocarat watchmaking experts want you to know that while this model is water-resistant, it is not designed for diving (professional or recreational) and should be kept away from high-pressure cleaning equipment. We also recommend against operating the crown or pushers while submerged.
