The 1969 Speedmaster Mark II was equipped with the hand-wound calibre 861 while the new model is powered by the Co-Axial calibre 3330, a self-winding movement complete with an Si14 silicon balance spring and a column-wheel chronograph mechanism.
Decorated with a dash of colour, the 2014 Speedmaster Mark II features a fluorescent orange central chronograph seconds hand and a matching minute track – a design feature that distinguishes the current model from its predecessor.
The transparent tachymeter scale on the sapphire crystal is illuminated from beneath by an aluminium ring filled with Super-LumiNova. The varnished white and black hour and minute hands are coated with Super-LumiNova as is the central chronograph hand.
The case is fitted with a brushed stainless steel bracelet, complete with OMEGA’s patented extendable foldover rack-and-pusher clasp.
True to character
The polished and brushed stainless steel case is barrel-shaped and has a polished crown and pushers. A date corrector is located at 10 o’clock on the case. The dial is complete with the three recognisable sub-dials popularized by the original Speedmaster chronograph: a 30-minute recorder at 3 o’clock, 12-hour recorder at 6 o’clock and small seconds sub-dial at 9 o’clock. A flat scratch-resistant sapphire protects the matt black or grey dial.
The caseback of the Speedmaster Mark II is engraved with the Seahorse medallion, “Si14” and “Column Wheel”.
