A rare British-Issued WWII ATP (Army Trade Pattern) watch, British Army military issue markings on the case back with 'Broad Arrow'

One of the elusive 'ATP' series, this Cortebert has quite literally been through the wars, but lacks the scars to show for it. A precursor to the famous ‘Dirty Dozen’ watches, produced for the British Armed Forces during World War II by 12 world-famous watch manufacturers (hence the nickname), the ATP (Army Trade Pattern) series of watches was made available at the start of WWII via a Military of Defence contract with 17 Swiss suppliers in 1939. Amazingly, in an effort to demonstrate neutrality, the Swiss supplied almost identical watches, this time with black dials, to the German military.

Just over 133,000 ATP watches were produced during World War II, and while the watches were meant to have been destroyed as fighting drew to a close, many were decommissioned and some continued in service. 

The Cortebert is generally regarded as one of the more aesthetically pleasing ATPs, and it's not a surprise when you take a look at this up close. The ornate chapter ring around the jet black Arabic numerals contains 'tropical' patinated hour plots, which have aged into a warm, smokey cream tone. This same ring is also seen in a smaller format around the sub-seconds register, which is easily distinguished by its slightly sunk appearance into the watch dial and its radial brushing effect, which glimmers in the right light. 

Particularly eye-catching on the dial is the blue tempered steel hands. This reflective, deep blue is the same metal surrounding the hour and minute hand lumes, and subtly radiates out when the face catches the sun.

What's on offer

The watch body is absolutely beautiful: a solid stainless steel, 31mm case with a smooth, flat bezel ring. The case polish is still sharp (amazing for a 1940s watch), and the watch seems almost immortal in its stubbornness to be physically marked or scratched. 

Unlike many subsequent Bravingtons or MOD redials, the 'Cortebert' signature on this is thin and in italics, indicating the dial's originality.
