Yesterday I wanted to do something I hadn’t done in quite a while: check my perpetual calendars. Especially since I had the Blancpain new acquisition in January.
The basic idea was this: although I bought the BP „new and unworn“, it had already been sitting around for a few years. So I wanted to make sure everything was truly working perfectly. And of course, to compare it with my other perpetuals.
I had it all nicely planned. I would sit down comfortably at 11:45 pm, line up the watches in front of me, and film the date transitions. In perfect light conditions. Relaxed.
Well… things turned out a bit differently. We had been out with friends and only got home at around 11:58 pm. So I improvised a rather “hectic” last-minute operation to document the switch from February 28th to March 1st. I was juggling several watches at once, using two iPhones at the same time. The lighting conditions were, let’s say, suboptimal.
A slightly crazy action. But perhaps interesting for you nonetheless.
My observations (calendar transition from Feb 28 to March 1):
1.
IWC Portugieser Perpetual Calendar Eternity: everything instant (in the 1. second after midnight). Unfortunately, I couldn’t use the first photo because it was so poor (my hands were trembling because I had always dropped its smaller sibling at midnight 😆). So this one was taken 42 seconds later.
2.
IWC Da Vinci Perpetual Calendar: everything instant (in the 2. second after midnight)
This is the poorest photo because I almost dropped the watch… 🙏
Photo taken also a few seconds later because I was still in shock.
3.
H. Moser & Cie. Perpetual Calendar Purity: everything instant (in the first second after midnight)

Here the photo was „in time“ because my better half helped me.
4.
Blancpain Villeret Quantième Perpétuel 8 Jours: just as romantic as the watch itself looks – leisurely, in small steps ☺️
With this watch, I could truly relax. 😆
00:06 – date changes to 31; slight movement already visible in the weekday and month
00:21 – month switches to March; date jumps to the 1st, weekday has moved a bit further
00:35 – weekday indicates Sunday, but lazily since the hand is not yet perfectly centered
01:01 – now everything is perfectly aligned
A little madness. I know.
And a catastrophic photo quality, but perhaps some of you still enjoyed this tiny journey. ☺️🙏
Have a wonderful Sunday, my dear watch friends.
