A reputable watch created initially for British paratroopers in the 1940s. The original piece was marked with the initials COSD and intended for the sole use of the Combined Operations Command created by the British War Office during the Second World War. The watch is housed in a 40mm steel case, with automatic mechanical Longines caliber L619.2 inside, and offered in choice of black or white dial. Maintaining its military look, it is fitted on a green NATO strap, though a black leather strap is also an option. The NATO strap and the distinctive broad arrow on the dial, used at the time for all military equipment, bestow its particular style to this model.
