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.
