The Speedmaster Ladies’ of the OMEGA Olympic Timeless Collection derives from the original gents’ Speedmaster, launched in 1957 and later chosen by NASA for its manned voyages to the moon. The Ladies’ Speedmaster uses a reduced case size and retains the classic tachometric scale on the bezel. The hour markers on the mother-of-pearl dial appear in the official colours of the Olympic Games—yellow, blue, black, red, and green—and complement the coloured rings on the counterweight of the central seconds hand. The heart of this distinctive model is the OMEGA calibre 3220 self-winding chronograph calibre; the movement’s high-performance winding system ensures a power reserve of 40 hours. This Speedmaster Ladies’ of the OMEGA Olympic Timeless Collection is protected by a sapphire crystal and is water-resistant to 100 metres / 330 feet. Available exclusively with a white alligator leather strap that subtly underlines its feminine elegance.
