Like the dashboard of a cockpit, the aptly named Flightmaster is packed with information that can be difficult to interpret at first glance. With practice, however, you’ll be able to use this Japanese quartz watch to summon all kinds of info: time, speed, and distance calculations; fuel consumption; climbing altitude, rate, and time; unit conversion; square root and rule-of-three calculations; and much more. That’s all thanks to the slide rule bezel, which features two logarithmic scales in addition to a tachymeter scale. But you don’t have to be a pilot to appreciate the Flightmaster.
