Daytona accuracy

[drefrank]

I know this isn't everybody's thing, but I couldn't resist tracking just how accurate my Daytona was over a period of time. So I set it using the Naval Observatory clock. From March 13 to November 6 (238 days) the watch lost just 59 seconds! I think that's pretty remarkable for a mechanical watch and is a testament to the quality of the movement (engineering, parts, assembly). Anyway, just wanted to pass this information along.

That's awesome.

I too have found the Daytona to be very accurate. I don't think I've ever heard of one not being accurate but I'm sure there must be.

Fantastic, keep it going until march 2012 so we see how much it loses in a full year

That's great but I always find these types of posts slightly depressing;

My Sub ND is gaining + 10 sec / day.

I'm envious.

The thing is - if I just get it serviced it'll come back well within COSC (-4/+6 sec/ day)

But with lead times of 20 weeks (UK) I'm loathe to part with it for that long.

Enjoy your accuracy but remember - it won't last - eventually the lubes will dry out and it'll start speeding up - just like mine and just like every other Rolex.

It's a passing thing.

In the mean time - You lucky devil.

1 minute in about 8 mos. That sounds almost to good to be true.
Thats one amazing movement you got there.

I would send it in if I were you. My 2 1/2 year old ND started gaining more and more time, when it hit 10 seconds a day I said, thats enough! Brought it to the AD I bought it from and they sent it to their own watchmaker. Got it back within 3 weeks and its been holding steady at
less than +2 a day since. Looking at my Sub knowing it was gaining that much time a day really bothered me. For me, it kind of took the joy out of owning a Rolex.

Agreed it does rather take the joy out of the brag of it being a mechanical watch, and accurate, etc but,

I don't mind.

I'm sourcing an independent watchmaker worthy of the job (here in the UK - and I can tell you, there aren't many)

But I'll get there and sort it. I'm sailing single-handed to the Azores next year - and I intend for the sub to be ship's chronometer - or at least think it is!!! (as well as the GPS, etc ) - so will sort it by then.
