Ollech & Wajs Astrochron Returns

Ollech & Wajs Astrochron Returns

The OW Astrochron story began in Zurich nearly 60 years ago, amidst history’s most ambitious era of exploration.

The race to go faster, further and deeper had the world poised at the edge of several new frontiers, the most notable being outer space. The astral realm represented the ultimate in exploration and inspired the name of the famous Ollech & Wajs 1967 triple-register chronograph (above left). Indeed, NASA’s most prestigious scientists would be among the elite professionals that used the Astrochron’s various dials and scales. 

Only a chronograph of outstanding quality would be worthy of continuing the Astrochron legacy, and the new version endeavours to ensure this new interpretation is equal to the challenge. With a water resistance of 50ATM (500 m), the new model more than doubles the depth rating of the original and far exceeds the Swiss chronograph standard. Other updates include a 360-degree rotating compass bezel and a 20-minute diver’s scale. As a final tribute to the original model, the new chronograph revives the distinctive North Atlantic blue dial of 1968 (below). 

Inside the brushed 316L stainless steel case is a descendant of the historic Valjoux 72 movement that powered the first Astrochrons. At the manufacture in the Swiss Jura, a custom-engraved automatic Valjoux 7753 – with an OW-machined rotor set onto it (below) – is regulated, adjusted and power-tested in five positions, thereby qualifying it for the OW Precision rating.

The OW Astrochron S is presented on the OW S-type Mark II bracelet, inspired by those found on many Ollech & Wajs models of the 1960s. Its links are individually machined in a solid block of 316L stainless steel, before being carefully brushed, assembled and screwed by hand, which prevents the usual stretching common among pressed steel bracelets, ensuring both longevity and comfort to the wearer. 

Whether you’re exploring a wreck, exploring a theory or just gazing up at the stars and exploring new possibilities, the new OW Astrochron could well be the perfect all-round chronograph.
