Ok, so I have to ask - As I have only had my first Rolex about 10 days I should really do some more scientific measurements.... but I think my watch gained about 10 sec in 8 days... is that exceptable and if it can be improved, how would one do that?

Mucho Appreciated!

Your watch is off by less than one second a day? Actually that's more than acceptable--it's outstanding!

I'm sure others will chime in on advice, but I'd just keep doing what you're doing because it's obviously working.

Welcome.

Let's see...That's about 1.25 seconds per day out of a possible 86,400 seconds....so a bit of math......

Hmmm, That's ~99.9% accuracy..

Don't think you can improve on that too much...

Probably good for a quartz watch. Mine's not that good.

I don't find mine to be that affected by position when not in use, by it's also possible your watch is gaining AND losing time and the net result is what you're seeing.

Thanks! Never thought of it as <1sec per day! Yup, good enough! I guess it bugs me that I have a aluminium bodied Swatch costing about £70 and it comes in at about 1 sec per week or so. But I don't like quartz movements - I love the idea of a little engine, ticking away in the key of G and doing it so well! It's got soul!

That's what it all about buddy.

Little works of art.

Enjoy!

I think people own a mechanical watch for the love of having a mechanical wonder with so many tiny parts working together to form a watch. 10 sec / 8days flaw is really good for a mechanical watch. If something more accurate w/ less maintenance is preferred, quarts is a way to go~

Welcome to the world of Rolex accuracy.
It will plague you forever wondering is ist fast, is it slow, crown up, crown down.
Bloody work of art though.

Nice to hear this! Nope, mechanical is the way for me - a wonder of engineering!

Excellent accuracy which at +1sec/day could probably be corrected to zero deviation by how the watch is positoned when not being worn. ie. crown up or down etc. This will work on most Rolex but not all to the same extent.

This chart came from one of Bo's threads - THANK YOU BO.

I gain about 2-3 sec in a24hour period, I will try the above and let you know what happens -A

entropydave · 20 November 2007, 08:00 AM

That is brilliant! Is this positional correcting method designed into the watch or a coincidence?

Downing · 20 November 2007, 08:10 AM

Oops. 10 seconds in 8 days is actually more, not less, than a second a day isn't it.

I am once again reminded why I'm a lawyer and not an engineer.

At least I got the "outstanding" part right.

SPACE-DWELLER · 20 November 2007, 08:15 PM

That's is excellent timekeeping since the COSC specs are minus 4 to plus 6 seconds a day.

Congrats!

SSD · 20 November 2007, 11:49 PM

I agree, that's really nice accuracy! Enjoy it in good health! BTW, what reference did you get, and can you post pics?
