JDM Military is a Swiss brand with worldwide recognition, celebrated for its timepieces that blend classic and innovative design. Their collections are crafted with the sophisticated, confident man in mind. From their Military Sapphire line, they proudly introduce the Alpha I JDM-WG001-01 watch - a refined piece built to grace men's wrists with elegance. The watch features a round, gray stainless steel case engineered for exceptional durability. With a brushed finish, it measures 40 mm in diameter and 10 mm in thickness, weighing in at 80 g. The dial is shielded by a sapphire crystal that guards against shocks and scratches. At 3 o'clock, a gray ridged crown makes adjusting the central functions a breeze. Designed to complement any look, this timepiece also features a screw-down caseback delivering a water resistance of 10 ATM.
The dial of this watch has a classic feel. With a sunray finish, it features a black color and makes reading the time effortless. It is crossed by a minute track with closely spaced graduations for precise timekeeping. This is complemented by silver-tone Arabic numeral indexes marking the hours. Two central sword-style hands with luminescent coating clearly indicate the hours with the shorter hand and the minutes with the longer one - even in the dark. The slim silver-tone seconds hand handles the precise and reliable seconds countdown. This watch's functionality is rounded out by a date window at 3 o'clock with a white background, displaying the day of the month. The brand's logo sits proudly at 12 o'clock, while the collection name, water resistance rating, and country of manufacture appear at 6 o'clock.
This watch is powered by a quartz movement - specifically the Swiss Ronda 515 caliber, which drives the hands and date window. It runs on a Sr920sw battery offering a battery life of 45 months.
This model features a black strap crafted from bovine leather. Enhanced with a crocodile-pattern finish, it is lined with tone-on-tone stitching and has a width of 20 mm at the lug. Securing the strap is made easy thanks to its silver-tone pin buckle.
This model offers a water resistance of 10 atmospheres, or 100 meters. Now that's a genuinely water-resistant watch! With its sporty personality, it's ready to dive into aquatic adventures right alongside you. From puddles to the pool, this timepiece handles water without complaint. Showers, baths, and laps in the pool - no problem. That said, our 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 keeping the crown and pushers clear of water during submersion.
