Ollech & Wajs Swiss Automatic P-104 Pilot's Watch #OW-P-104

The OW P-104 descends from an era when aviators, engineers and navigators relied on their watches to help them make complex calculations on the ground and in the air. It’s not based on a single OW reference but inspired by an assemblage of pilot’s slide-rule watches made by Ollech & Wajs in the 1960s and 70s. Designed with today’s military and commercial pilots in mind, the P-104 S is equipped with a circular slide rule to determine differential speed, distance, range and other data.

The dial configuration and design resonate with cockpit control panels, oversized indexes and chequered hands are applied with orange Super-LumiNova® for maximum readability.

Its robust mechanical movement ETA 2824-2 OW3, adjusted in five positions, makes the P-104 a reliable navigation tool for high-flying pilots. The movement’s mainplate is engraved with ‘Ollech & Wajs Zurich 1956’ and fitted with our own machined rotor, bearing the famous OW propellor monogram.

In keeping with Ollech & Wajs’s long-held reputation for extreme water resistance, the P-104 boasts a depth rating of 300 m / 30ATM – impressive for a dive watch, let alone a pilot’s watch. The watch is assembled and adjusted in Haute-Sorne in the Swiss Jura, at the historic workshop that has served OW for over 60 years.

The P-104 is presented on a premium-quality, highly durable and water-resistant RAF regimental-style nylon band, hand-finished with a brushed stainless steel thorn buckle, signed ‘OWZ 1956’.

The P-104 has an optional S-type Mark II beads-of-rice, stainless steel bracelet. This bracelet was inspired by those found on past Ollech & Wajs models of the 1960s. Its links are individually machined in a solid block of 316L stainless steel, before being carefully brushed and screwed together by hand. This process prevents the usual stretching common among pressed steel bracelets, ensuring both longevity and comfort to the wearer. The bracelet’s double-lock deployant clasp prevents accidental opening.
