The Watch
Water-resistant to 20 atmospheres, refined in design, and powered by a reliable, high-performance movement - this March LA.B timepiece has everything it takes to win you over. It's the perfect companion for men who want a chic, elegant watch that works just as well in everyday life as it does beneath the waves. Its story begins in 1957, when American filmmaker Peter Viertel arrived in Biarritz and introduced surfing to France. The case is crafted in stainless steel with a silver tone, and its bold, masculine proportions measure 40mm in diameter and 16mm thick. A domed sapphire crystal sits over the dial to protect the timekeeping indicators, complete with an anti-reflective coating for maximum legibility. The case is surrounded by a 60-minute graduated rotating aluminum bezel - ready to track your performance on land or at sea. The crown, positioned at 4 o'clock, allows you to wind the movement. The screw-down caseback ensures 20ATM water resistance and is engraved with the iconic Villa Belza.
The Dial
Finished with a sunray effect, the dial wears the brand's signature color: green. Three luminescent hands mark the hours, minutes, and seconds from center, while baton-shaped hour markers around the perimeter are also treated with Super-LumiNova for easy legibility even in the dark. A railroad minute track runs along the dial edge for added precision. The date window at 3 o'clock displays gray numerals on a black background. At 12 o'clock, the brand signs its name with its logo; opposite, the collection name and the mention "Made In France" pay tribute to this timepiece's French manufacture.
The Movement
Designed by manufacture La Joux-Perret and assembled in France, the G100 caliber drives the hours, minutes, and seconds hands. This automatic movement stands out with a power reserve of up to approximately 68 hours. It also powers a date window positioned at 3 o'clock.
The Strap
Choose your strap from the dropdown menu. March Lab offers this Belza watch on a black NATO strap, a black silicone strap, or a stainless steel bracelet. The NATO and silicone straps feature a stainless steel pin buckle, while the steel bracelet comes with a deployant clasp. The watch lug width is 20mm.
Water Resistance
With water resistance to 200 meters - or 20 ATM, in the precise language of watchmaking - this watch is built for casual water activities and shallow dives. That means it can handle the shower, the bath, the ocean, and the pool for recreational (non-professional) dives, including freediving. For professional scuba diving with tanks, our Ocarat watch team has hand-picked a dedicated selection of 30 ATM models available in our catalog. One last reminder before we let you go: never operate the pushers or crown while in the water.
