IWC Schaffhausen has launched two new variants of the Portofino Manual Winding Eight Days model.

In the first model, the IWC debuts using a gray suede bracelet, which matches with a slate-colored dial.

In the second model created specifically for this line, another novelty: the Swiss luxury watch manufacturer combines a Milanese steel bracelet with a blue dial.

Both IWC models are powered by a 59210 caliber and offer 192 hours, which equates to 8 days of precise operation.

After that, the movement stops automatically, although it is designed to run smoothly for nine days.

The power reserve integrated with a separate dial reminds the owner to wind the watch at the right time.

The transparent sapphire glass allows the user to visualize the movement, adorned with «Côtes de Genève».
