You can look forward to this little ritual all week long: winding your Portofino by hand to provide the timepiece with energy for the next eight days.

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.
