Hamilton Khaki X-Mach

Nowadays, getting past the speed of sound has become a regular occurrence, especially in the world of aeronautics. The Mach number has become a familiar unit that can now be measured by your wristwatch. The Hamilton Khaki X-Mach pilot’s watch does exactly that. Simply input your calculated air speed plus your altitude, then the X-Mach will display just how fast you’re going relative to the speed of sound, or Mach 1. Movement is from the Valjoux 7750 and the watch is encased in a PVD-treated stainless steel with a sapphire crystal. Choose between black or brown leather straps or the more durable rubber. Not that you’d want to be submerged in water in or mid-flight, but the X-Mach is water resistant up to 100 meters. $1,650.
