Nickel case, screw bezel, with hinged fold-out movement holder. Comes with protective metal case as used by military and miners. All in very good condition. Uses Revue Thommen calibre 31 negative set 15 jewel movement.

To access movement, unscrew front bezel, pull up crown to the setting position, and lift up movement from depression at front of case. Serviced last year so in good working order. Happy to answer questions on this watch if you have any, please feel free to get in touch. Will be carefully packed and posted RM Tracked 48. This is an antique/vintage watch likely dating from between 1910 and the 1930's so around 100yrs old. I do not know its history prior to my ownership. It will not be in perfect condition.
