Been a while since I bought any military issued watches due to they are not cheap these days. Think I buy one a year these days last year was a Hamilton model 21 ships Chronometer use to buy 2-4 a year when prices were better. This year I picked up this another Hamilton a 6B 9101000 H issued to the RAF in the 1960's good size 18mm lugs and 36mm case. Got it at the MWR forum PX for a fair price compared to others I seen for sell lately.
