Based off the original ALT1P pilot’s watch, the definitive aviation chronograph, the hardened DLC case and black dial of the ALT1-P2 JET combined with our iconic ’51 lume’ offers total clarity and legibility to the wearer. Passionate about celebrating British engineering and innovation as part of the testing cycle we have teamed up with veritable aviation pioneers Gravity Industries to test the new watch. This is the first DLC-coated case in this line and turning the watch over reveals a smoked crystal exhibition case back with black rotor continuing the stealthy aesthetic. Stainless steel bracelet.
