An 'Army Trade Pattern' watch scribed to the reverse of the dial A.T.P 92179 with broad arrow. The 'pattern' for these watches destined for the Armed forces was 'a watch case from 30 to about 34mm, a white or silver dial with black numbers for legibility, a small second or 'running seconds' on the dial to aid in more precise timing co-ordination, fixed bars at the lugs, reliable movement of 15 jewels or more, hands and dials need to be luminous'. Seventeen swiss watch companies answered the call to make these and they all have slight differences. This watch is in great condition with only a few scratches to the glass, manual wind up and leather strap.
