This style of watch replaced the Smith's W10 & was the last general purpose mechanical watch ever issued to the military in the UK! "Tonneau" shaped case watches were issued to all 3 branches of the M.O.D Army Navy & RAF from 1973-1980. There were 3 makers of this watch style throughout the 1970's - Hamilton CWC & a M.O.D own-brand. Hamilton who have been supplying watches to the MOD from WWII won the first contract & supplied this style of watch mainly in 1973 & 1975 Movement- Swiss ETA 2750 re-branded by Hamilton as Cal-649 (21,600 BPH) Mechanical wind 17-Jewel with Hack feature.
