Within the Sous-Marine collection, you'll find this stunning diving watch born from the brand's CoLAB initiative, which invites the community to contribute ideas. Offered as a limited edition, it is perfectly suited for water sports enthusiasts. It features a silver-toned case crafted from brushed 316L stainless steel. Round in shape, it measures 37.50 mm in diameter, 48.20 mm lug-to-lug, and 10.45 mm thick - dimensions that sit beautifully on men's wrists. The case is topped by a unidirectional 120-click ratcheted bezel featuring a round SuperLuminova marker that glows in the dark. It is graduated with a minute track and fully coated in black PVD for a bold look. A domed sapphire crystal 2.92 mm thick shields the dial from everyday scratches and impacts with outstanding effectiveness. An anti-reflective treatment ensures excellent legibility from every angle. The Parmentier crown at 3 o'clock provides smooth adjustment of the hands and date window. Finally, the screwed caseback is engraved with a diver motif and delivers a water resistance rating of 20 ATM.

The Dial

This watch features a round tropical dial in brown, a refined accent for your wrist that ensures excellent time readability. Its perimeter is framed by a minute track for added precision, complemented by Arabic numerals and baton indexes marking the hours. These indicators, along with the three hands mounted at the center of the dial, feature an old radium lume treatment for reliable legibility in low-light conditions. The three hands display hours, minutes, and seconds. A date window sits at the 3 o'clock position. Finally, the brand name is printed at 12 o'clock, while the collection name appears at 6 o'clock.

The Movement

This model is powered by a Swiss-made automatic movement - specifically caliber AM5, featuring 24 jewels, ensuring reliable performance across all functions. It delivers a power reserve of 68 hours and beats at an oscillation frequency of 28,800 vph. The movement is fitted with a tungsten rotor and a seconds-stop device.

The Strap

This watch comes with two elegant straps that are easily interchangeable. Both measuring 20 mm at the lug width, they each bring a fresh look to your timepiece and add effortless charm to your wrist.

The first strap is made from black FKM rubber. Its flexibility ensures all-day comfort, and its perforations allow the wrist to breathe. It fastens with an 18 mm pin buckle.

The second strap is crafted from stainless steel with an elegant brushed finish that enhances its refined look. Fixoflex and silver-toned, it transitions effortlessly between dressy and casual styles. Comfortable and stylish, it is expandable.

Water Resistance

This model offers a water resistance of 20 atmospheres, or 200 meters. A true companion for deep-water activities - it's built for freediving. Pressure washers? Not a problem with this watch on your wrist. Showers, baths, lap swimming, and freediving are all fair game. That said, we recommend a higher water resistance rating for scuba diving with tanks. Also, avoid operating the crown while submerged to protect the movement's integrity.
