OLLECH & WAJS OW P-104

All about the OLLECH & WAJS OW P-104

The OLLECH & WAJS OW P-104 comes from a time when aviators, engineers and navigators relied on their watches to perform complex calculations on the ground and in the air. It is not based on a single OW reference, but is inspired by a series of pilot's slide watches produced 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 that determines differential speed, range, distance and other data let.

The P-104's dial is configured and designed to resemble cockpit control panels. The oversized hour markers and checkered hands are coated with orange Super-LumiNova® to ensure maximum legibility.

Its robust mechanical ETA 2824-2 OW3 movement, adjusted in five positions, makes the P-104 a reliable navigation instrument for high-flying pilots. The movement's main plate is engraved with "Ollech & Wajs Zurich 1956" and features our own milled rotor bearing the famous OW Propeller monogram.

In keeping with Ollech & Wajs' long-standing reputation for extreme water resistance, the P-104 boasts a deep diving capability of 300 m / 30 ATM - impressive for a diving watch, let alone a pilot's watch. The watch is assembled and set in Haute-Sorne in the Swiss Jura, in the historic workshop that has served OW for over 60 years.

The P-104 S comes with the OW S-Type Mark II Rice Grain Stainless Steel Bracelet. This bracelet was inspired by previous Ollech & Wajs models from the 1960s. The links are individually milled from a solid block of 316L stainless steel before being carefully brushed and screwed together by hand. This process eliminates the usual stretching common to pressed steel bracelets, ensuring both durability and comfort when worn. The bracelet's double-locked folding clasp prevents accidental opening.

The P-104 comes with a high quality, highly durable and water resistant RAF regimental style NATO strap. Alternatively, there is a 20mm wide Italian black leather strap with natural linen, lined with a soft tan base and embossed with the OW emblem. Both bracelet and strap are handmade in Switzerland and are equipped with a brushed stainless steel pin buckle, signed "OWZ 1956".
