To achieve this gradation (from light-blue to midnight blue), which lends great depth to the color, more than thirty layers of varnish, followed by colored and transparent lacquer, are successively applied. Next comes the polishing, for the finishing touch. Equipped with the Calibre 761 with integrated chronograph mechanism – featuring a column wheel with vertical clutch for optimum accuracy – the Polaris Chronograph offers 65 hours of power reserve. Offered with a pair of interchangeable straps – one in metal, the other in blue rubber – it is designed to accompany you in all of your daily adventures.
