Well out of COSC spec

Lawrence · Post by **Lawrence** » Fri Feb 18, 2022 2:24 am

I've had three watches returned to CWL for issues, one was a broken crown (most likely something I did) and two go back that had been magnetized and were galloping at full speed.

CWL fixed all 3 without cost to me. Pretty amazing from my point of view especially since the first magnetized one to go back I'm pretty sure was done by airport screening equipment. I tried to pay but they'd wouldn't even entertain the idea.

Good kick in getting your watch back to COCS specs.

I was generous in my first post. It is actually +22 seconds in the last 24 hours.

I would still try and check if it is magnetized, even slightly. Very quick fix if it is.

Back to CW Towers it goes. Returns label and bag on its way.

<controversial>
I too have previously had a (admittedly small) number of NN purchases which have been well out of specification- to include performance issues, obvious rotor drag and even loose casebacks. I would love to know to what degree watches assembled in Switzerland and shipped over to the UK are checked after being mated to the strap/bracelet, boxed and sold. Similarly I'd love to get reassurance that NN items are given a thorough going-over before being resold- including checking performance to specification. Cynically, I sometimes suspect that attention is given only to the cosmetic condition.

To the OP, a fast watch is frustrating, sorry to hear that- but in many cases is easily remedied- sometimes even without opening up the watch. If you intend to be a fan of mechanical watches, I can heartily recommend purchase of an inexpensive compass to check for magnetisation.... I check each watch I buy and periodically across all my watches especially when I suspect the rate may be drifting. The watch you have may or may not have been magnetised, but even if it were supplied perfect, it's really easy to become magnetised during everyday use. At least by checking whether it is magnetised before condemning it you would know whether there's something seriously amiss requiring proper regulation or whether it's worth investing in a cheap demag. At some point, many folk find they need one.

The compass idea is a useful one for magnetization, and if that is all that’s wrong, a local jeweler can zap it while you wait for next to nothing. Annoying to have the problem at all since you just got the watch but usually an easy remedy.

Loads of things contain magnets. I bought a few tiny neodymium magnets to put a metal picture on a fridge. About 8mm x 4mm, maybe 1.5mm thick. Just insanely powerful as well as being very dangerous. I am careful to keep them well clear of watches.

They don't just house magnets, they house rare earth magnets. Some rare earth magnets are the strongest permanent magnets on earth. I've never seen the actual type of magnets Apple uses for example but they have a list of products that shouldn't go near any medical devices.

The watch has been back with CW for six weeks. Now I know repairs take 8+ weeks, but this should be a simple regulation of the movement, not a major repair.

It feels like all work, however large or small, is completed in series.

So, it appears you wait the same length of time for movement strip down when compared to a simple regulation.

I feel that something as simple as regulating a movement should be completed quicker than this.

I suspect that CW take each watch sent back to them in turn irrespective of the fault.
I sent back my C65 SC OC as it was running well out of spec (so just need regulating) - it took 7 weeks and 2 days (door to door).

I'm sorry for asking but what does it means "NN"?

My Dartmouth is in COSC specs - 2-2.5 spd. It's actually very good. The only problem is that my previous watch (I'm wearing only one watch for months) was extremely accurate - 0.5 spd.

So a returned watch re-selling? Roger that.

After a few hours, or maybe longer, they seem to settle down to a more accurate level. Maybe the lubricants need a few hours to get going again.

Me too. And sometimes some of my watches also.
