Victorinox Chrono Classic XLS Watch

This hefty timepiece by Victorinox—a 45-millimeter chronograph weighing about 7 ounces—carries its weight by offering tons of functionality. The tachymeter bezel is helpful not only in measuring fuel and oil consumption but also in converting units of measurement, calculating distance, and measuring speed. It can even be used to solve math problems. And then there’s the chronograph, which is controlled by the two oblong pushers at 2 and 4 o’clock. In addition to providing 12-hour and 60-minute totalizers at 9 and 6 o’clock, the chronograph counts seconds on the main dial and allows for split-second timing.
