The Speedmaster is now a very large family, with a lot of variants introduced over the years. The Speedmaster ’57 that Omega presented at Baselworld 2015, due to reach the market in August-September 2015, has a lot of the vintage looks of the original – the smooth tachymeter bezel, pushers without crown guards, the dramatically differentiated hour and minute hands – and a lot of differences as well. With respect to the 1957 Speedmaster, the notable difference is in the dial layout, with two subdials instead of three, and above all the size. The original Speedmaster (2915K) was 38.5 mm, and over the years, dial size increased just as in the entire watch industry, to 44 mm and over. The Omega Speedmaster ’57 is back to a very wearable 41.5 mm, thickness 16.17 mm.
A vintage look is provided by the vintage beige-colour SuperLuminova used on the recessed hour markers and the hands. It glows green in the dark. The hands present two design types, broad arrow for hours, and alpha for the others. The subdial at three o’clock provides chronograph hours and minutes in a combined counter which to my mind is the most practical of all for lengthy time lapse measurements – it’s just the same as the main dial and so you can immediately see how many hours and minutes have passed.
While the original Speedmaster had a Lemania movement, the Speedmaster ’57 is powered by the Omega Co-Axial calibre 9300, running at 28,800 vph (4 Hertz), visible through the sapphire caseback. The two barrels provide a power reserve of 60 hours. The case is water resistant to 100 metres; the watch is supplied with a 4-year guarantee.
