The chronograph version displays matt black, opaline and midnight blue, colours as elegant as they are refined. Several zones feature on its dial, and a tachymetric scale - quite rare for a Longines watch - also enriches its circumference, just like on the original model. The Longines Heritage Classic Chronograph - Tuxedo houses in its 40.00 mm-diameter case a movement (calibre L895.5) developed exclusively for Longines Heritage timepieces. It is also equipped with a silicon balance spring.
