OLLECH & WAJS OW Astrochron

All about the OLLECH & WAJS OW Astrochron

OLLECH & WAJS OW Astrochron is a chronograph of exceptional quality and is worthy of continuing the legacy of the Astrochron today and we have strived to ensure that this new interpretation rises to the challenge. With a water resistance of 50 ATM (500 m), the new model far exceeds the deep diving capability of the original and exceeds the Swiss chronograph standard.

The estimated delivery time is approximately 6 weeks from the order date.

OLECH & WAJS OW Astrochron in detail

Additional updates include a 360-degree rotating compass bezel and a 20-minute diving scale. These additional features, combined with a five-minute regatta counter, extra thick sapphire crystal and a unique four-sealing pusher system make the new OW Astrochron equally competent above and below water.

Inside the brushed 316L stainless steel case is a successor to the historic Valjoux 72 movement that powered the first Astrochrons. In our workshop in the Swiss Jura, a individually engraved automatic Valjoux 7753 - with a rotor manufactured by OW - is regulated in five positions, adjusted and tested for power reserve, giving it the OW precision ratingreceived.

As a final homage to its predecessor, the new chronograph revives the striking North Atlantic blue dial from 1968.

The OW Astrochron S is presented on the OW S-Type Mark II bracelet which is inspired by those found on many Ollech & Wajs models of the 1960s. The links are individually crafted from a solid block of 316L stainless steel before being carefully brushed, assembled and screwed together by hand. This process prevents the usual stretching common to pressed steel bracelets, ensuring both longevity and comfort for the wearer. The bracelet's double safety folding clasp prevents accidental wear Open.

The OW Astrochron also comes with a handmade Perlon regatta strap, ideal for summer activities. Woven exclusively for OW - made from high quality, lightweight and highly water, salt and oil resistant braided nylon - The Regatta band offers a pleasant mix of comfort and durability. The distinctive two-tone pattern reflects the dial colors of the Astrochron, and those familiar with the international maritime signal flag system may also recognize the nautical code for J - Juliet. The band is completed with a brushed stainless steel pin buckle, signed "OWZ 1956". Combined with the Astrochron's extreme deep diving capability of 500 m, this seafaring complement is up to any challenge – in, on or around the ocean.

Whether you're exploring a wreck, investigating a theory, or simply looking at the stars and discovering new possibilities, the new OW Astrochron could be the perfect all-round chronograph.
