Ollech & Wajs (Switzerland) Ref. OW Astrochron – On Perlon Strap

> IN STOCK AND READY TO SHIP <

“The OW Astrochron story began in Zürich 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. Indeed, NASA’s most prestigious scientists would be amongst the elite professionals that used the Astrochron’s various dials and scales. Engineers, sportsmen, commercial and military divers, pilots and ships officers were also fast to appreciate the value of such a rugged and water-resistant precision timing instrument.

Only a chronograph of outstanding quality would be worthy of continuing the Astrochron legacy today, and we had endeavoured to ensure this new interpretation is equal to the challenge. With a water-resistance of 50ATM (500m), the new model more than doubles the depth rating of the original and far exceeds Swiss chronograph standard. Other updates include a 360-degree rotating compass bezel and a 20-minute diver’s scale. These additional utilities, combined with a five-minute Regatta counter, extra-thick sapphire crystal and unique four-gasket pusher system, make the new OW Astrochron as proficient on the ocean as it is under and over it.

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

As a final tribute to its forebear, the new chronograph revives the distinctive North Atlantic blue dial of 1968. Whether you’re exploring a wreck, exploring a theory or just gazing up at the stars and exploring the possibilities, the new OW Astrochron could well be the perfect chronograph. As has become a new OW tradition, the first 56 Astrochron watches will be offered with numbered crowns.”
