Founded by professional diver Frank Huyghe, RALF TECH designs, develops, manufactures, and distributes dive watches built to be precise, reliable, and rugged. Today, the manufacture introduces the new version of the WRV - the Electric Black "Ecume". Inspired by military aesthetics and the design codes of the 1970s, it delivers discretion and stealth to whoever wears it. Boldly surprising, this watch comes in a distinctive tonneau case with smooth, taut lines that radiate confidence and power. It is crafted from 316L surgical steel with a matte black PVD treatment and measures 43.8 mm in diameter. It pairs with a unidirectional rotating bezel with 120 clicks for precise dive time calculation, featuring a matte black Ceramfine® insert with a triangular SuperLuminova® C5 marker at 12 o'clock. The large knurled screw-down crown is protected and positioned at 4 o'clock for exceptional wearing comfort, handling the setting of hours and minutes. The crystal protecting the dial is a domed sapphire, 3.5 mm thick and scratch-resistant, with an anti-reflective coating. Finally, the caseback is sealed to the watch via an exclusive encapsulation system, guaranteeing optimal water resistance to 30 ATM.
The WRV asserts its own personality through a design that is both vintage and contemporary. It features a matte dial that echoes the color of sea foam, whose contrast gives the watch a stealthy aesthetic. It is dressed with a minute track and black bar indexes. The 3, 6, 9, and 12 o'clock positions are marked by Arabic numerals. The baton hands and seconds hand are crafted from 316L surgical steel with a high-gloss black PVD treatment. They are printed with a luminescent «SuperLuminova®» Black X insert for outstanding, impressive legibility. Below 12 o'clock sits the brand's signature, while below 6 o'clock the mention "300 M/Electric" highlights this model's defining characteristics. The result is an impeccable design with incredible construction.
This WRV Ecume is powered by an electric RTE001 movement developed and manufactured in Switzerland exclusively for Ralf Tech. This one-of-a-kind movement operates on a micro-hybridization system with an autonomy of up to 100,000 hours - nearly 12 years.
This model comes with two highly comfortable straps, both 26 mm wide - one in black silicone and one in black Zulu nylon. Both straps feature signed pin buckles.
This model offers water resistance to 30 atmospheres, or 300 meters - built for everything from poolside play with the kids to serious professional scuba diving. The deep sea doesn't stand a chance. The Ocarat team wishes you a great dive, with one last tip: don't touch the pushers or crown on the way down!
