NAUTOSCAPH

Designed for Depth, Defined by Heritage

The Nautoscaph draws its inspiration from Alsta’s own 1960s dive watches, reimagined to meet the rigorous demands of contemporary exploration. Its distinct skin diver case shape pays homage to the era when form followed function, resulting in a design that is as enduring as it is practical. With 300-meter water resistance, a screw-down crown, and C3 Super-LumiNova ensuring visibility in the darkest depths, every detail is meticulously engineered for reliability. The unidirectional rotating bezel provides a precise tool for divers, while the watch’s case—available in 316L stainless steel or high-grade bronze—balances durability with an elegance that evolves over time. The dial selection reflects a bold, adventurous spirit: from the deep hues of Blue Shark and Great White to the striking tones of Tropic (Orange) and All Red in steel, or the ever-changing patina of bronze in Black, White, Porcelana, and Anacapri casing.

For those seekinhg a more adaptable option, the Orca strap -- a high performance rubber strap inspired by Quint's boat in Jaws -- is available across the range.
