The Omega Seamaster Bullhead was introduced in 1969. It is powered by the hand-wound caliber 930, which is turned 90 degrees counter clockwise in order to get to the bullhead look. It features an internal rotating bezel. The case measures 41.5 * 42 mm and is made of stainless steel. Together with the Flightmaster, it is one of the most notable examples of Omega's late sixties creativity in design.
