IWC Portofino iw510107 Hand-Wound Eight Days 45mm

In The Portofino Hand-Wound Eight Days, The Iwc-Manufactured 59210-Calibre Movement Will Run Precisely And Reliably For A Full 192 Hours, Or 8 Days, Before It Automatically Stops. Strictly Speaking, It Is 9 Days, But The Extra Day In Reserve Ensures That The Movement Maintains As Constant A Driving Torque As Possible And Continues To Run Precisely. The Owner Will Always Be On The Safe Side If He Winds His Watch Once A Week. The Power Remaining Can Be Read Off On The Power Reserve Display On The Dial. Together With The Small Seconds Display And Date Display, This Gives The Dial A Pleasing Equilibrium. The Indexless Balance Has A Frequency Of 28,800 Beats Per Hour And, Together With The Breguet Spring Bent Into Shape In Accordance With Age-Old Watchmaking Tradition, Helps To Make The Watch Exceptionally Accurate. The Watch Is Available With An 18-Carat 5n Gold Case, Silver-Plated Dial And Solid Gold Indices. It Has A Transparent Sapphire-Glass Back And A Dark Brown Alligator Leather Strap From The House Of Santoni.
