This is a non-luminous single button White Dial Series 3 Lemania Chronograph as used by the Royal Navy specifically for use onboard nuclear submarines. These watches were non-luminous in order that the onboard radiation measuring devices would not be affected.

The rear case of the watch has the Broad Arrow marking followed by Admiralty Stores Reference Number 0552/924- 3306 3312 and the unique issue number 80683.

The case, dial, hands, crystal, and movement are all original to the watch and are all in excellent condition.

The watch is 41.5mm diameter including the crown and 13.5mm in thickness.

The watch is working correctly, and all functions operate as they should. The movement is the superb Lemania calibre 2220 and is in lovely condition although it has not been serviced during my ownership.

The watch has spring strap bars and is designed to take a 20mm strap.

Overall, a very nice example of a watch which is becoming increasingly difficult to find in original condition and presents a good opportunity for the military watch collector.
