The Longines Heritage 1973 is based on a chronograph model produced by the brand in 1973.
Black (ref. L2.7188.8.131.52) or silvered (L2.7184.108.40.206), the dial of the Longines Heritage 1973 features two counters at 3 and 9 o'clock: black on the silvered dial and silvered on the black dial.
The applied hour symbols are decorated with a fine black line and a dot of Super-LumiNova. A blue tachometric scale surrounds the dial, adding a subtle touch of colour to the whole.
The back is fitted with a transparent sapphire glass cover showcasing the movement with its blue column-wheel.
