It was at night. It was dark. And the lighting conditions were really bad.

So please sorry for the bad photo quality. But I spontaneously decided last night to film this "event".

It is amazing how my Moser Purity Perpetual Calendar jumped from February 28th to March 1st.
It all happens in less than 1 second: just after midnight the large date jumps on three days and the month display (the small hand in the middle of the dial) jumps from February to March.

I don't know of any other perpetual calendar where this happens just after such a short time after midnight and at this speed.
Fascinating…

A PC is an admirable technical masterpiece, but if we're honest, it has little practical relevance unless you wear the watch all the time.
You just have to set it again and again.

For me it's different with this Moser: with an official power reserve of seven days (in reality it's eight days), this manual wound perpetual calendar is not only beautiful, but also very practical.

Thanks for reading.

All the best
Thomas

Just wanted to ask the forum if there are really jumping dates at the end of February and there is my answer. Great watch! My Ochs and Junior takes a few hours to perform it (obviously another approach by Oechslin). On the note of the potential resetting ...

Thank you for your comment, Dirk!

As far as I know Moser is the only manufacturer that offers the function of an immediate jump of the date. The watch can be set using the crown any time of day or night. So you can adjust the date forwards and backwards all the day. Even on March 1st you ...

Moser, a brand that sweats the details

Impressive result!

Thank you, VinnieD!

Yes, the details are impressive. I also love the fact that the perpetual calendar is only discernable on the dial as the large date and the very restrained design of the hand for the month, here very reduced even with hour indices just at 12 and 6. Best T...

Yes, very quirky in the good sense of the word

To my knowledge H. Moser is the only house having a pc with this function

Actually the Endeavour Perpetual Calendar is not only a very beautiful watch with this very recognizable design but is also powered by a very smart movement that enjoys instant daily date change at midnight (including on Feb 28th indeed) and also is the o...

Thank you for your comment and wishes, Mike!

The movement was designed by Strehler, as far as I know. You can safely change the date at any time of day without causing any damage to the movement’s workings. It’s a PC for dummies. LOL If I would try the same for example with a Valjoux 7750 I would ha...

Certainly a very different approach to a perpetual calendar display. Every time I stop at their AD here and look at Mosers any small dose of fiscal responsibility I might have begins to rapidly

I am a big fan of Moser. I had some issues with my first Moser I bought in 2015, the Henry Double Hair Spring, which has a very complicated and apparently delicate movement, that was produced just in a very small number. But Moser could fix it the second ...
