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 WatchTime’s February 2018 issue (on sale now), here are six watches that are (almost) ready for eternity.

  1. 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.

    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.
