OLLECH & WAJS OW Navichron

The OW NAVICHRON comes with an aged natural leather and linen vintage racing strap, handcrafted by one of Italy’s finest tanneries. The luxurious strap is finished with a brushed stainless-steel pin buckle, signed ‘OWZ 1956’.

The OW NAVICHRON S is presented on the OW S-Type Mark II bracelet, inspired by many Ollech & Wajs models from the 1960s. Its links are individually milled from a solid block of 316L stainless steel, before being carefully brushed, assembled by hand and screwed. This process prevents the usual stretching common in pressed steel bracelets, ensuring durability and comfort for the wearer. Its double-lock deployant clasp prevents accidental opening.

OLLECH & WAJS OW Navichron

Today’s OW Navichron is powered by a Valjoux 7753-based two-register chronograph. It follows a long lineage of Valjoux chronographs, with highly regarded historical references such as the V72, V92, V7730, V7733, and V7750. OW has developed its own precision rating, reserved only for the highest quality movements. We start with a Valjoux 7753 in a brutal matte finish, which we then reassemble with our own machined rotor, bearing the famous OW propeller monogram. We engrave the main plate with ‘Ollech & Wajs Zurich 1956’ before removing the hour counter. We then reassemble, regulate, and test its precision in five positions, as well as its duration.

The OW Navichron maintains a 12-hour gliding bezel, allowing travelers to tell the time in different zones. It is also a highly capable professional diver’s watch, featuring a 20-minute dive scale on its bezel, like the original Navichron of 1967. It boasts a specially reinforced case, extra-thick sapphire crystal, and unique four-gasket pushers, capable of withstanding pressures exceeding 50 ATM. Its markings and hands are equipped with Super-LumiNova®, ensuring maximum visibility in all conditions, above and below the surface.
