Quick TakeThis is the Legend Diver, sized just right at 39mm for any adventure. That deep blue dial isn't just for looks; it's the command center. Twist the top crown to set your dive time on the slick internal bezel—no accidental bumps will move it. Underneath, a certified chronometer heart beats reliably, packing a 3-day power reserve and shrugging off magnetic fields. It’s a vintage soul with a modern-tech brain, ready for the weekend, whether that's 300 meters down or just down the street.

DescriptionThe timepiece is constructed from stainless steel, featuring a round case with a diameter of 39.00 mm, a thickness of 12.70 mm, and a lug-to-lug dimension of 47.00 mm. The lug distance measures 20 mm. Case specificities include a screw-in crown and a screw-down case back, which contribute to its water-resistance rating of 30 bar. An internal turning diving flange is integrated into the design. Protecting the dial is a scratch-resistant sapphire crystal treated with several layers of anti-reflective coating on both sides. The total weight of the assembly is 81.8 g. The watch is secured by a blue nylon strap equipped with a buckle.

The dial is rendered in a blue lacquered polished finish, displaying hours, minutes, and seconds via silvered polished hands. Legibility is enhanced by painted Arabic numerals and indexes augmented with Swiss Super-LumiNova®. This model houses the Caliber L888, an officially certified chronometer movement. The self-winding mechanical movement is engineered to be magnetic resistant, incorporating a monocrystalline silicon balance-spring and operating at a frequency of 25'200 vibrations per hour. It provides a power reserve of up to 72 hours.
