I have been Looking for a Lemania WW2 for a long time...A Dirty Dozen British Army service watch made by Lemania, Switzerland, circa 1944.
The Dirty Dozen watch with large satin silver plated brass turned case (47.0 mm x 35.0mm excluding crown), and contract, screw case-back. It has the Typical black dial with the Lemania trade-name, and War Department arrow. The dial with 1-12 hour digits, 60-second scale with luminous hour-marks. Subsidiary seconds-dial at 18.00hrs.
To the reverse, case-back with markings, 'Q4113' War Department arrow. The inside to the case-back with War Department arrow and serial number. The high quality, 15-jewel movement with nicely-finished mercuric gilt main bridges. The Lemania c.27 designation impressed to the bridge.
