IWC Portofino Eight Day Manual Wind Watch

The Portofino Manual Winding Eight Days, which contains a manufacture caliber 59210 movement, proudly ensures that the watch runs for 192 hours, or eight days, with precision and reliability, before stopping automatically. In fact, nine days even. The one-day reserve is used to ensure that the drive torque is as constant as possible for eight days, which ensures high precision throughout the entire operating time. By winding his watch once a week, the owner is assured of optimal running precision. The time remaining before the movement stops is indicated on the power reserve display on the dial. With the small seconds and date, the dial offers a harmonious design. The balance wheel without a racket oscillating at a frequency of 28,800 vibrations per hour guarantees a high degree of precision, as does the Breguet hairspring with a terminal curve, originating from ancient watchmaking tradition. The watch comes in a fine steel case with silver dial and solid gold indexes. It has a transparent sapphire crystal back and is worn on the wrist with a brown alligator strap from Santoni.
