Nad, now that is sooo....nice! Must have been a time-lapsed shot no? And the watch matches the true moon slice - even better.
I understand that that shiny thing in the sky is meant to be the "SPOT" a Single Point of Truth and the scholars tell us that our entire "hobby" is based on it's cycles. IWC put it down as in the extract below. So the only question is - have you got it within the 12 second range. I bet you do !
Assuming, there is not so much difference (I assume) between your PPC and the 5021.... Thanks for sharing.....
IWC Extract:
The view of the lunar phases is reminiscent of classical representations of the moon, whose waxing and waning is due to the presence of two semi-circles. This is the method chosen by watchmakers over the centuries to depict the “celestial arena” in gold. In view of the extra space available in the large movement, the moon phase wheels in the IWC perpetual calendar now have more teeth, making the mechanism one of the most accurate available. After 577 years, the deviation from the moon’s actual progress will be just one day. For the Portuguese Perpetual Calendar IWC developed a countdown display that can be used to read off the exact number of days remaining until the next full moon, a phenomenon that has been steeped in mystery and legend since time immemorial. Many people believe it has an influence on them, while in many cultures special festivals are celebrated on nights with a full moon. It is in any case undisputed that the moon and its gravitational pull determine the ebb and flow of the tides and thus have an influence on the earth and our lives. The moon in the hemisphere lunar display on the Portuguese Perpetual Calendar measures just 5 millimetres in diameter – about 700 million times less than in reality. Nevertheless, its representation of the course of the moon deviates by just 12 seconds from the actual time taken in each lunar period. The phases of the moon are displayed for both the northern and southern hemispheres.

Keep in mind that the moon phase on IWC watches do not continually advance - like a second hand. They quick-advance at Midnight - in 24-hour increments. The multiple gear ratios in the Portofino, and Portuguese Perpetual Calendars are precise enough to be just one 24-hours in 577 years - or 12 seconds in one lunar cycle.
I saw the moon and it all made sense regarding the moon phase adjustment, LOL!!!!!
Thanks everyone for your input on this.
Here's the photo I look last night around 5:30PM (well, it was dark anyway!!!!):
A couple of photos taken a few minutes ago this morning:
Cheers,
