YOU SHOULD KNOW : When the Speedmaster Broad Arrow 1957 ref. 3551.50.00 was launched in 2002, the watch marked the latest interesting homage to the history of the iconic Speedmaster collection. Notably familiar with classic vintage-inspired attributes seen in its namesake "broad arrow" handset, 42mm steel case with twisted lugs, and highly legible tri-compax dial – all of which derive from original models from '57 – the design also reinterpreted and remixed, prominent applied hour indices, and function-focused 6 o'clock date window. The result is a distinctly sporty Speedmaster with just enough vintage charm to draw you in, but plenty more modern intrigue to keep you engaged. The model is powered by OMEGA's caliber 3303, an automatic mechanism based upon the Piguet caliber 1285. The movement is capable of a 55-hour power reserve and is chronometer-certified, all the while being protected via a solid caseback that further secures its 100m water resistance.
