I\u2019ve made it no secret that I love field watches<\/a>, so it only makes sense to dive into the history of the \u201cDirty Dozen\u201d. This is the name given to the original 12 military field watches issued during World War 2. These somewhat sterile-dialed, no-nonsense military watches were the first modern field watches, and without them, modern classics like my Hamilton Khaki Field<\/a> might not exist.<\/p>\n\n\n\n The history behind these watches is already extensively covered, so I\u2019d like to focus on the twelve brands that produced them. This will be a three part series, and part 1 will kick it off with Buren, Cyma, Eterna, and Grana. <\/p>\n\n\n\n This series will showcase vintage post-war ads that are from the immediate post-war era (as in after the end of WW2). A time when things started to settle down and \u201cget back to normal\u201d if you will.<\/p>\n\n\n\n The 1950s was an innovative time for Buren, which filed a patent<\/a> for its micro-rotor movement in 1954. This innovation, which allowed the rotor to be integrated at the same level with the rest of the movement, allowed for very thin automatic watches. It wasn\u2019t until 1957<\/a> that its first micro-rotor movement went into production, however. Through a series of refinements, the \u201cIntramatic\u201d movement was born. This was the base movement that would inevitably be modified into one of the first automatic chronographs.<\/p>\n\n\nBuren Advertisement From 1950<\/strong><\/h2>\n\n\n\n
