Sherpa Ultradive Atoll | Rubber Strap | Pre-Order

The Sherpa Ultradive Atoll captures the spirit of endless summer with its captivating turquoise dial inspired by the luminous beauty of ocean atolls. Its delicately domed face, painted in shades of aqua blue and framed by a white inner diving bezel, evokes sunlit waters and soft white sands. Crafted from stainless steel and protected by Sherpa’s signature EPSA-STOP bayonet compressor case and handmade MONOFLEX crowns, this 40 mm dive watch is certified water-resistant to 200 meters, making it as reliable beneath the waves as it is refined on land. Every detail, from the diamond-cut indices to the signature double-lollipop seconds hand, reflects the perfect balance of functionality and artistry.

Ref. 002/01/01-Atoll

Inside beats the Swiss-made Mantramatic MM01 automatic movement, based on the premium Sellita SW200-1 calibre, decorated with a gilt finish and a custom rotor. This exclusive mechanism also features Sherpa’s patented “spiritual complication,” housing two micro Tibetan Buddhist prayer wheels within the movement, an homage to mindfulness and motion. Paired with your choice of robust Tropic-style vulcanized rubber strap or an optional stainless steel bracelet (sold separately), the Ultradive Atoll is the luxury compressor dive watch for those who carry the ocean’s tranquility wherever they go.
