With box and original bracelet (rare to find).
The watch that Longines produced to celebrate the Munich games was a manual-wind monopusher chronograph that was released with a blue, navy or silver dial (here proposed in the silver dial version). The blue and vibrant orange seconds hand on this model are particularly evocative of a watch from the 1970s. The Olympics reference is displayed on the caseback.
As mentioned, this is a monopusher chronograph. Inside is the Longines Calibre 334, which is a base Valjoux 236. The 236 is derived from the Valjoux Calibre 23 column wheel chronograph, which was the successor to the Valjoux 22, a movement that was in use from 1914 to 1974.
Going by the name of the Conquest XX Munich Olympic Games (Ref. 8614), this 36mm x 42mm stainless steel watch has a chunky 1970s aesthetic to the case and uses plexi atop. You may notice that this exemplar still has both its original box and bracelet.
