    What is the typical accuracy of a Rolex/Tudor or Panerai?

    I am asking because colleages watchfriends told me that they need to adjust their Rolex for minutes gain or loss every month!

    I am beginning to think that no mechanical watch is 100% accurate...

    Thanks,

    Bruno in Belgium

    My Rolex runs almost dead-on. Less than 1 second variation per month

    Methinks your friend's Rolex needs a cleaning.

    The accuracy of mechanical watches is absolutely terrible! You'd better just stay away and leave them to us. Us humble watch folk tend to live life a few minutes behind (or ahead of) the rest of the world. Believe me, you're gonna be saving a ton of money!!!

    Seems like some basic research is in order. Classical Rolex COSC certification would provide -4/+6 specs. Recent shift to Superlative Chronometer certification means -2/+2 specs (seconds per day). Many will perform better.
    Simple math will tell you that -2/+2 sec/day variance equates to 1 minute per month. That is damn precise and more accurate than vast majority of watches out there (mechanical).

    Now GS Springdrive could deliver better accuracy, but it uses quartz oscillator and is not 100% mechanical.
    And new Zenith Defy Laboratory promises vastly better accuracy, but that may be awhile before it's commercially available and is not a very fair comparison.

    So the question I have - what's the point of original question? if to state that quartz will outperform luxury mechanicals, even some of the most accurate ones like Rolex, well duh - most people know that already. If to ask how much time gain\loss one can expect - many Rolex may perform way better than specs, but even a 1 min per month variance is not an issue. Unless you have a perpetual calendar - you can always sync the time when changing monthly date on 31st. And honestly - 1-2 mins per month - who gives a damn.

    Say a COSC watch gains 30s a week and a 4 week month. The watch gains 2mins. per month so as Bruno’s friend said it is running minutes ahead of time each month. Of course most months have more than 30 days and +6s/ day is allowed so this a conservative figure.

    And just to add to this - no watch is 100% accurate. Quartz, even HAQ, will still allow for some variance (up to 15 sec/month for std quartz, and 5-10 seconds per year for HAQ from Citizen or GS)

    Want closer to 100% - get atomic one that synchronizes constantly. Granted that's more of a smart computer\radio than a watch as it does not keep the time, but rather updates from another source on regular basis
