Stores reference 6E/50. Swiss made 15-jewel movement. White metal case approximately 5cm diameter. White dial with Arabic numerals and blued steel hands plus subsidiary seconds dial. Screw-backed case with worn War Department broad arrow markings, '6E/50', and serial number. The dial is quite good but a little discoloured/spot marked. The case has normal wear and tear. Very good crystal. We have been unable to unscrew the back but the movement is in good working order when test run for 24 hour periods. Pocket watches like these were preferred by navigators who found it easier to place the watch on their maps and charts whilst working. Stock code C26091.
