My 321 re-issue gaining 15 seconds a day...

Would you say this is more or less acceptable or shall I go to an Omega Boutique to get it regulated?

It's a November 2020 watch. Never been serviced, but as the 5 year warranty expires in November this year, I might send it away for regulation anyway?

All input and advice appreciated! 馃榾 I'm based in the UK.

Omega's average precision tolerances for non Chronometer/Master Chronometer watches are between -1/+11 seconds per day. Given that, you are probably out of spec and it is worth getting it looked at while you are still under warranty.

Just wait till a month before the warranty expires to get it checked out. Chances are they will do a thorough service.

Note that 321 will be sent to Biel if you used Omega service. So the wait time will be long.

Using a compentent independent watchmaker for checking/regulating is good enough IMHO.

I鈥檇 be interested to know what the Biel turnaround time is if you decide to go down that route. Appreciate this may some time away but useful information nonetheless.

As Baz suggests above, I would guess there is a 90% chance you will get a free service if it indeed is running out of spec. The downside will be the wait but you are saving the thick end of a grand this way so it may be worth it. I have found them very very accommodating when it comes to problems under warranty, and indeed sometimes outside of warranty. It is a pity that the 321 is Bienne only since Southampton turn warranty stuff around very quickly, in less than a month in my recent experience. Even so you may find its not as interminable a wait as a regular service.

I find it interesting that the 321 is not master chronometer certified. I guess I just assumed it was.

It would be very, very difficult to get a 321 certified, it's a design from the 1940's. Ain't gonna happen, and that's not its mission brief anyhow.

Omega shifted the numbers a bit a while back, so instead of being -1 to +11, it's now 0 to +12 - same spread just shifted one second.

For the 321B, the specs are as above for average rate. The tolerances for positional variation are 25 seconds at full wind, and 30 seconds 24 hours after full wind - note that this is measured over only 3 positions, not 5 as for COSC, or 6 as per METAS. So the max tolerances here are not exactly screaming a high level of accuracy by any means...

It wouldn't be that hard at all. Accomplishing this doesn't require a co-axial escapement (Tudor has done it with a good old Swiss lever), so it's mostly changes in materials for parts of the escapement and balance. The big one being the balance spring would need to be changed to silicon (it would be flat - no over coil), and aside from that make the balance staff and some other parts from non-magnetic materials and it would likely pass.

But as you say that's not the point here. This isn't a watch people buy for accuracy...

Current one is on my list, unless a 1966 comes up in great shape.

Personally I'd also just bring it back 1 month before the warranty runs out 馃榾

To start with, I would get it demagnitized by a competent watchmaker. It's cheap and there's a real chance that fixes the issue without need for opening the caseback or being without your watch for months.

I had a Rolex with a 3135 that would get mildly magnetized and the rate would jump from +2 seconds a day to something like +10 to 15 seconds a day. I have my own demagnetizer so I would do that and the rate would return to a stable +2.

I'd just take the watch in now and have it taken care of.
