Do watch movements settle in?

[gofore59]

Sorry if this is off topic because it relates to my Cartier, but the wealth of information on this site is far superior to any other out there I figured I would ask...

I just got my Cartier Roadster XL back from Cartier service on Saturday and it is running fast (I would say 1 + minutes every 24 hours). My service rep told me they completely replaced my movement, hands and crown (the power reserve kept failing after 2-8 hours and I had taken it in several times to no avail).

Will a watch movement "settle in" after a break in period?

I am hesitant to take it right back because the service rep is outstanding to me - the service was free of charge on a 5 year old watch! Also, I need the watch for some engagement photos and my wedding which is coming up...

Should I try to self regulate the watch by placing it in a certain position overnight?

Thanks!

PS - My 14060 got daily use over the last 3 weeks and it is such a comfortable watch to wear - it must be half the weight of the Cartier!

In my watches, I notice maybe my new movements settled in after a few months time of 1/2-1 second in a 24 hour period from it's new accuracy test. I always test my new watches accuracy as soon as I get them. COSC is a real easy achievment to make. Most all my watches are well under COSC spec. My 12 year old serti Sub has been +3 seconds in 24 hours from new till now and never setteled in in 12 years. My Omega Planet Ocean is +1 second in 45 DAYS!

I would take it back. From my experience, the timing gets worse with age on all of my watches. I have never heard that a movement will settle in, I could be wrong though. I am no expert by any means.

I think that the movement may change by a second or two........ but not nearly as much as you seem to need........

Had you said that it was a few seconds outside of COSC I would have said to leave it for a month or so while it settles into your wearing pattern but IMO there is no chance that a watch of that calibre will self correct 1 minute /day.

Older Rolex movements, for example, seem to respond to positional corection but non of my newer Rolex watches (3135, 3186, 3131, 4130) seem to vary at all, overnight, in any position.

If it were my watch, I would take it back to be regulated as it is not right. Cheers, Bill P.

I took it back to Cartier and they put it on the machine (not magnetized) - the main spring in the new movement is too strong - it reads 3.55 instead of 3.1 (???). They are going to put another new movement in the watch...

I would normally be upset in a situation like this, but they are so nice and accomodating. I could not believe it when they gave me a new movement, new crown and new hands free of charge. Cartier in Beverly Hills is really tops.

In the meantime its back to the 14060...
