Eternal Time: 6 Modern Perpetual Calendar Watches

In modern watchmaking, a perpetual calendar indicates the date, and corrects automatically for months with less than 31 days, as well as leap years. Unless the movement takes into account century years that are not leap years, a watch with a perpetual calendar will need manual adjusting in 2100, 2200 and 2300 but not in 2400. Usually, a perpetual calendar combines additional complications (a moon-phase, for example). From the WatchTime archives, here are six watches that are (almost) ready for eternity.

    Such sampling provokes always the questions: what was the purpose of this article, b) why just these were selected? Imho the article had been more valuable by including more examples and advising also to their specialities e.g. IWC with the Kurt Klaus movement, Blancpain Villeret with their special adjsutors any time possible etc. A limititation had been necessary too, but had given more value than just the typical price information.

  2. The Jaeger Lecoultre master perpetual calendar is more attractive and a better value than any of the above.

  3. Steve Schall

    You forgot Jaeger Lecoulter master ultra thin perpetual calendar. Nicer and simpler than any of them you showed.

  4. Patrick Freel

    Nice watches but all terribly expensive. Are there any affordable watches with perpetual calendars?

  5. Peter Currer

    Although such complications are nice to admire and/or own, the humblest digital with a year setting (some don’t) has the calendar programmed in for several decades that cover the watch’s probable life.

  6. Brian Anderson

    If the perpetual calendar function only requires adjustment once every century, why do all these watches feature a sub-dial to indicate the leap year? Does “perpetual” actually mean correction every February 29th?

    • Because they account for the usual leap year every four years. However, years divisible by 100 but not by 400 are not leap years.

  7. Frank Pontillo

    why was the Jaeger Le Coultre not included in your portfolio ? Its the best value for the dollar.

  8. Joseph Gelfand

    The IWC Da Vinci and Portugeiser perpetual calendars do show the actual year (which I think is a huge plus vs a fairly uninformative Leap Year indicator) and, as the Da Vinci IWC perpetual calendar was the first to be set entirely from the crown, was an important modern update on this complication….

  9. David Jackson

    I would NEVER buy a perpetual calendar watch that did not display the year. None of these qualify, quite apart from my inability to afford most of them.

  10. There’s a glaring omission here. There’s nothing modern about any of these. The only modern perpetual calendar movement that isn’t just a minor evolution on something that’s been round for 100 years is the H. Moser & Cie. Endeavour

  11. Crispin Bates

    This is not very advanced technology. My Seiko Perpetual Calendar watch has kept perfect time for more than eight years on a single battery and it cost only 22,000 Japanese Yen (or approximately $200).

  12. I would think that a Kurt Klaus PC would be a must whether in its IWC Portuguese guise or my fave the JLC Ultra Thin Perpetual (black dial, steel) – best value in the market.

  13. Excuse me, did I read well, you said:
    “Unless the movement takes into account century years that are not leap years, a watch with a perpetual calendar will need manual adjusting in 2100, 2200 and 2300 but not in 2400”
    Unless you are including quartz movements -which I’m sure it’s not the purpose of the article- could you please indicate which mechanical perpetual calendar movement in this world takes into account the century years that are not leap years.
    As far as I know such a mechanical movement it doesn’t exists so, please either mention at least one or correct the article.
    All perpetual calendar mechanical watches in the world will need manual adjusting in 2100, 2200 and 2300 but not in 2400.
    A magazine like you can not make such a mistake.
    Best Regards.

    • Surprised your query has not been answered, yet, but, yes, there is one perpetual calendar watch that will not require manual adjusting in 2100, 2200, 2300 (assuming of course you mean sent to the factory). That is the Ulysse Nardin 326-22/92 and its ilk. They, like the IWC Kurt Klaus models adjust the calendar solely with the crown, and the UN is also unique in that the user can move the date both forward and backward with the crown. Just an FYI (I know this is a response to a very old post.)

      • I’d also like to note the Andersen Geneve Secular Perpetual Calendar, a suuuuper badass indie creation

  14. David Jackson

    All very nice, but for me the watch has to show the actual year rather than having a quadrant indicator. I hope, being a manual wind, that the Lange watch is easy to re-set.
