This IWC Portugieser Perpetual Calendar 42 Replica 42 movement no longer uses the long-term 7-day movement, but is powered by a simpler but stronger movement with a more traditional 60-hour power reserve. The new movement is also thinner, so the height of the case is only 13.8 mm, compared to 14.9 mm before.

As the name implies, the case of the Perpetual Calendar 42 is 42.4 mm and is available in rose gold or stainless steel, which is the first in the regular series.

Unusual eternity
The Substantial IWC Replica dial retains the traditional perpetual calendar configuration and has three sub-dials for calendars (making the 7-day version clearer and easier to read). It also includes a central second hand, which is extremely rare in perpetual calendar watches.

In the IWC Portuguese Replica, a simplified calendar module is combined with cal. It reached 82000 for the first time. 82650.

The movement is obviously less than 7 days calibrated. The Replica Watches in the 44mm model (30mm vs. 38.2mm) is a much simpler movement. The most obvious difference is the single-barrel transaction, not the double-barrel transaction of the 7-day campaign.
