c.1939 Cortebert ATP WW2 Official Ordnance Military Gents Watch 
 
The Ministry of Defence only officially ordered 133,000 from various Swiss Manufacturers in 1939, known affectionately as Tommy Watches these predated the famous Dirty Dozen by a number of years and were used in the heaviest fighting in WW2. 
After the war those that hadn't been lost or destroyed the `MOD tried to destroy, however not all were and that makes these watches very collectable now. 
This watch is actually in very good condition for its age,steel case is in very good condition,  its dial has  possible wartime experience although not showing too much wear.
 
The Army Trade Pattern Mark and Pheon (ATP) is clearly engraved on the back.
Inside the case is a 15 Jewel cal.665 movement signed Cortebert.
 
Cosmetically overall this is in very good condition and running well
