    What level of Accuracy is acceptable to you?

    I have a feeling this may have been asked before, but couldn't find anything in my search so here goes.

    At what level would you RETURN a MECHANICAL watch? I'm talking new watches here, as vintages can vary quite a bit.

    Perpetual means Automatic; Datejust lets you adjust the date; A Superlative Chronometre is COSC certified; A Rolex President has an adjustable day and date

    Well, it still depends. I've got a new Vostok that does around +40/50s a day but that's fine with me. But I would surely not accept it on a watch that costs 10 times as much..

    COSC spec is acceptable

    +1 For the average affordable anything less than a minute a day is pretty ok for me. I rotate my watches so I only really need it to be accurate enough to not cause a problem for 1 day. My worst is my aviator at around 25 seconds a day.

    If I was buying a Rolex or something though I'd expect it to be less than 10.

    Re: What level of Accuracy is acceptable to you?

    I think it depends largely on the watch. For example on a Vintage watch that you really want, you might find that you will tolerate an erratic movement, because you know it is ineed of an overhaul. then again on a brand new quartz loosing 5 second a day, you would have a cow then of course there is everything in between.

    Personally on a new or serviced mechanical I'm happy with +/- 15 seconds per day. the reason is that i rarely wear a watch for more than one or two days, so that type of deviation would go unnoticed by me by the time I strap a different watch on.

    If your watch looses 6 hours a day it's still 75% accurate ((6*60*60)/(60*60*24) = 0.25). If your watch looses 15 minutes a day it is still 99.98% accurate.

    That being said, if it gains / looses more then a minute or two I'd contact the company.

    Re: What level of Accuracy is acceptable to you?

    Would I return a new watch just because it wasn't running as accurately as I'd like? No. If it's not running the way I'd like I'd get it regulated. I suspect many companies don't spend much if any efforts regulating their watches - many have very liberal specifications as to how accurate their watches should be. If a company states that it's acceptable for their movements to be +/- 30 seconds/day, that's probably because they don't really regulate them all that well. There may be new movements that aren't more accurate than that, but every watch I've ever had could be regulated to be much, much better than that.

    I'm finding that I really want my watches to run accurately. When I first started collecting good watches they were mostly 6497/8 based ones (I like large watches) Those are positionally sensitive so I could set them down as needed at night to gain or loose a few seconds as needed. I've regulated all those watches so that I can keep them within a few seconds of true time for as long as I care to.

    Recently I've gotten a few automatic watches, mostly ETA 2824s. Those don't seem to vary as much so I can't really set them down at night to gain or loose. I have a couple that are around +1 sec/day (one came that way - dumb luck, and another I regulated), but a few others are running perhaps +3-5/day. I know that's still within COSC specs, but honestly that's not good enough for me. 5 seconds fast/day is still 2.5 minutes/month. Eventually I'll get around to regulating those watches to be better.

    But there's no way a company is going to accept a return on a new watch because it's running 5 seconds fast/day...

    Re: What level of Accuracy is acceptable to you?

    THis is a tough questions, as you have to determine what specifically is being targeted.

    Are we talking: Digital vs Auto?

    If Digital: Atomic vs non-atomic? If atomic, I would expect -0/0 per day due to the resynch every 24 hours. If non-atomic, than -5/5 may be acceptable per month.

    Automatic: COSC or non-COSC? Vintage vs non-vintage? Hand wound or rotor round, etc.

    The list goes on...........

    For this poll, I selected -5/5 per day, as it was the closest to COSC spec I could find in the answers.

    Re: What level of Accuracy is acceptable to you?

    I was kind of freaked out by the fact that my brand new IWC was running at +5s/day in the first week of acquiring it. It didn't get much wrist time in the first week but once I've started wearing it more often the accuracy has definitely gone up. It is now running less than +2s/day and I am very happy with that. Maybe you just need to "burn in" the new movements (I'm no expert, lol).

    I would return the watch to an AD to have it checked-up and regulated if it is running more than +/-10s/day though.
