The Sherpa Ultradive is a modern revival of a 1964 icon, an automatic dive watch that blends vintage character with contemporary Swiss engineering. Its 40 mm stainless steel case features the legendary EPSA-STOP bayonet compressor system, ensuring 200 meters of water resistance without the need for screw-down crowns. Distinctive details like the double-crown design, domed sapphire glass, and curved dial with faceted, diamond-cut indices showcase the artistry behind this piece. The upper crown controls the internal diving bezel, illuminated with Sherpa’s signature dayglow orange Swiss Super-LumiNova Grade X1, offering both high visibility and bold visual contrast.
Ref. 002/01/01
Underneath its refined exterior lies the Mantramatic MM01 movement, based on the Sellita SW200-1 Top Grade calibre, featuring fine gilt finishing, custom decoration, and the world’s first “spiritual complication” with twin micro Tibetan prayer wheels. The Ultradive’s iconic double-lollipop seconds hand and luminous dial create an unmistakable presence, balancing elegance with rugged functionality. Paired with a black rubber strap and available with an optional add-on stainless-steel bracelet (sold separately), this compressor dive watch embodies Sherpa’s dedication to craftsmanship, heritage, and timeless adventure.
