Gallet Flying Officer

The Gallet Flying Officer was the first pilot’s chronograph to allow changes to time zones on the fly. With a quick glance at the outer dial of his wristwear, a pilot in 1937 could reference one of 24 major cities and make the necessary horological adjustments with a spin of the bezel. While Gallet isn’t usually the first name to be bandied about by collectors, they have an extensive history dating back to 1685 and claim to have produced the world’s first wristwatch. If that’s not enough, former President Harry Truman was known to flaunt a Flying Officer from time to time, so you know they’re tough.
