Aeronautics has informed watch design since the 1930s and this concept by Germain Baillot is no exception despite its modern time-telling functionality. Unlike flat-faced pilot watches, this alternative timepiece features a vertical tourbillon. The watch indicates the time by hour and minute markings on the outer rollers, while the center roller displays the major time zones. The crowns on each ends unscrew to adjust the watch (Hour/Minute and GMT). Whether you’re an aviator or just want to look like one, you’ll appreciate its masculine, turbine-like form and classic leather strap that has the appeal of a nicely broken-in bomber jacket.
