Picked up a Cockpit clock yesterday, GWO, nuclear timepiece accuracy. AWaltham ABU/11a apparently. All the ones on t'net are US kit with all they're guff on the back. Mine has a sterile dial and just has numbers and a Broadarrow stamped on the back, so I'm assuming it's M.O.D? Some debate as to wether they are Lemania or Waltham, where they were made/assembled etc.....

Can anyone here enlighten me, what it came out of etc?

Ta.
