Yes, Andersen Geneve makes one. It's actually called the "Secular Perpetual Calendar"
Jun 11, 2022,21:05 PM
It addresses the "secular year" that happens once every 100 years for 3 out of every 4 centuries. The backside of his watch actually accounts for it and tracks the next 400 years.
Absolutely marvelous. But it does beg the question: Do I need to swap out the backside dial in 378 years?

Easy answer, at least for me

Minute repeater is The complication. We've seen that Tourbillon can be "easily" manufactured, and I'm not even referring to the cheap Chinese turbo, instead of the Tag Heuer. But there is no mass production of minute repeaters, at least AFAIK
Hey Nico, that would be interesting to know!

The best I can do to guess the number of produced minute repeaters is go to that large global watch marketplace and search for the number of minute repeaters for sale worldwide on the secondary market. It appears that there are around 180 mechanical minut...
Wow. Thanks, Nico. I'd say the MR qualifies then!

Just curious, do you happen to know of any producers of secular perpetual calendars? Andersen is the only one I can think of and his are produced by request these days. I don't know of any producers of a secular perpetual calendar outside of Andersen. It ...
Secular?

EDIT: I can't seem to figure out how PM works - if you can PM me I would appreciate it. And thanks for the intro to Julien - I can't wait to see his creation. 10,000 years in a mechanical watch boggles my mind.
Hold on a sec....

Is your reasoning for steel Rolex watches being more expensive than QP's and tourbillions is due to modern manufacturing? "[T] he perpetual calendar (again, simplified by IWC's da vinci) that can now be found on the secondary market for less than most Rol...
I was surmising about perpetuals
By: destrodan : June 11th, 2022-20:11
Patek became the masters of mass-producing perpetuals (along with very few select others) until IWC made the complication ubiquitous. For the first few years that the IWC Da Vinci perpetual hit the market, they outsold all other swiss perpetuals combined....
I would disagree about rattrapante
By: MrkK : June 11th, 2022-22:18
Yes, while cheap mostly Valjoux 7750 based rattrapante chronographs were plantiful (thanks mostly to Jaquet), properly executed modern rattrapante are still rare and very expensive. Just think who is making them nowadays: Patek, Lange, Breguet, RM, Czapek...
That's a fair observation.
By: destrodan : June 12th, 2022-00:47
There is a difference between a properly executed rattrapante and one that is less refined. And chronographs in general are one of the most complex of complications even if they are ubiquitous. I would say the same difference exists when one considers per...
