From IWC, the Portofino Automatic with a black alligator leather strap features striking gold hands on a silver-plated dial and is optionally available with a Milanese mesh bracelet in stainless steel. The solid, mechanical automatic movement reliably ticks away the time. The evenly rounded sides of the 40-millimeter stainless-steel case make it appear even slimmer. The sun-pattern finish on the dial underscores the luxurious appearance of these timepieces.Case:Stainless steel caseDiameter 40.0 mmHeight 9.2 mmWater resistance 3 barMovement:35111 CalibreAutomatic, self-winding42 hours Power ReserveFrequency 28800.0 vph (4.0 hz)163 Components25 JewelsCôtes de Genève, perlageFeatures:Date displaySapphire glass, convex, antireflective coating on both sidesCentral hacking secondsIWC Style #: IW356517
