C60 Elite 1000 Accuracy

Post by Tricky17 »

Hi. I have recently purchased an Elite 1000 watch and am wondering about accuracy / timekeeping. I have only had the watch 2 weeks and was wondering what accuracy I can expect from a new COSC watch, which I understand should be within +6 / -4 seconds per day. I wear it during the day and take it off overnight. It was out of COSC for the first week then settled down to about -3 / -4 seconds a day but for the last 3 days has been losing 6+ seconds per day. It has lost 3 seconds during the day today while on my wrist all day, which is worrying me. Therefore, I have some newbe questions.
Should it have been within COSC specs from the start or does a new watch need time to 'bed in' and if so how long?
Do I need to invest in a watch winder for overnight or just keep it on?
Will the orientation of the watch overnight affect accuracy? The COSC certificate implies face down was the most accurate in the tests and I have been leaving it face down but it still lost about 3 seconds overnight.
Will it be sufficiently wound on my wrist or do I ned to manually wind it too? I understand that the level of wind can affect accuracy of a watch, is this true of a COSC watch too?
Are there other factors I need to take into account, or do I just need to contact Christopher Ward?
I know it is only a few seconds but I paid for a COSC spec watch so I really want COSC accuracy. Other than that I am really pleased with the watch.
Any help and advice will be greatly appreciated.
Thanks in advance, Richard.

People do report watches need a settling in time. Who knows if that’s true or not. I’ve seen it myself though.

It may need to be wound further. Depending on how active you are, it may not get a full wind, and low power reserve can affect accuracy.

Placement also does affect accuracy.

Winders may or may not be required. Really more of a personal preference.

It certainly should be within COSC spec though and CW should take care of it if it’s not.

Welcome to the forum, BTW! The C60 elite is a pretty great watch in any case.

I'm pretty sure that when I've worn watches that probably haven't had a lot of wear, they need a bit of time to settle down.

Also, I have a couple of watches with a power reserve, and they definitely run less accurately as the power runs out. Without a PR it's hard to tell whether the watch is actually fully wound.

Thanks for the replies. When I wind the watch I get to a point where the resistance increases and I stop winding then, under the theory that it is fully wound. I understand that you can't overwind an automatic watch but have read about stripped teeth on the cogs. I will give it a bit of time and try different positions for it overnight. Thanks, Richard.

I would give it a full wind & then wear it all day & see where you are at.
Power reserve can affect accuracy & so can positioning, try it face up overnight & see if that helps.

The movement would have been measured by COSC when it was much newer than it is now and I'd assume that watches slip out of adjustment with use and wear rather than "getting better".

I'm with the advice that you give it a full wind, wear it like you'd normally wear a watch (all day every day?) and check performance at say 6 or 8 hourly intervals.

If you're still unhappy I'd let CW take care of it.

Oh and it might be irrelevant but when receiving a watch through the post I worry about the effects of being bounced around whilst in transit and give it 24 hours recovery time even though I know there is no foundation in fact for my anxiety.
