Inspired by a model made by the brand in the 1970s, The Longines Heritage 1973 is a concentrate of vintage look and contemporary mechanics. The dial is faithful to the original, the steel case is cushion-shaped. For the chronograph made in 1973, the brand had chosen the Longines 30CH mechanical movement, while the new model houses the L688 calibre, a column-wheel chronograph movement developed by ETA exclusively for the brand. The sapphire crystal caseback reveals its finishing. It is fitted with a tachometric scale and has a black alligator strap.
