Built to Last a Lifetime of Exploration

Alsta strives to draw on its heritage and provide best in class skin diver timepieces, focusing on thinness, mechanical precision and elegance of design.

The modern Nautoscaph follows the design language of the original, however, it has taken on some different looks, such as coloured dials and even a bronze case. The elegance of the Nautoscaph has remained even though the dimensions have increased. The ruggedness and waterproofness is at the heart of the Nautoscaph and despite its elegant looks, it is made to withstand the knocks and bumps of any good adventure.

The Nautoscaph started life as a skin diver, and is still a skin diver at heart, although it is rated to withstand professional dive depths. This is where the Nautoscaph will continue to sit in the Alsta line. Tough enough for the mountain face or the ocean and elegant enough for the board room or the dinner table.
