Reference 3910 The Portofino Chronograph brings a sporty touch to the Portofino family. The striking push-buttons are reminiscent of the cockpit of 1960s Italian sports cars. The watch, which features a convex sapphire glass and appliquéd Roman numerals, is driven by either the automatic 79320 or 75320 calibre, both with a 44-hour power reserve.
