Hi Guys

I want to get my new PO 8500 perfect its gaining +2 a day its well within spec I know, but this little baby could do better ?? My POLMLE gains +3 a week whats the best place in London to get it adjusted ? Thanks Steve.

PS This whats its about with these Omega Movements getting them perfect , now I know that it will take a bit of time to settle down over the coming weeks but what are people experincing with there's?

If you have a mechanical watch that gains two seconds per day and you don't think that is good enough, you really need to ask yourself why you bought mechanical in the first place. Cracking open a brand new watch to fiddle with almost perfect timekeeping is just crazy.

I reset my watches when they get off by a minute, not because that minute is critical to meeting my obligations, but because that's the arbitrary standard I use. Using that yardstick, you would reset your watch every month. Seriously, is that not good enough?

Why won't they do it? Because your watch is running within COSC specs.
They don't advertise the limits of COSC specs for nothing. Simply because some of their owners are obsessed over how many seconds their watch gains or loses per day doesn't mean they will open your watch to regulate it. That is not a warranty-related service.

My PO is currently gaining 1.8-2.0secs/day... I'm quite pleased with it. I'm happy to just to wake up and see it still running when all things involved in a mechanical watch operating are considered...

If improving the accuracy will add to your enjoyment of the watch, and it's worth the risk to you, then by all means you should do it. I personally wouldn't touch it, and I suspect the vast majority here wouldn't either, but that's not really relevant to what you want from the enjoyment of your watch. Of course, keep in mind it could come back with worse timing, or with damage.:-( I realize that's not an answer to your question about where to take it, however it is somewhat relevant to other people's experiences. On a related note, I bought a brand new skyfall AT from a local AD just over a week ago, and in the first 8 days it gained just under 14 seconds total...pretty good in my view, and there's no way I'd risk anyone, even the AD I bought it from, opening it up to tweak the movement.

If it voids the warranty then, obviously, opening the watch wouldn't be the best course of action.
Otherwise, I can't see the problem with having an experienced, expert watch smith look over it.
If this is how the OP wants to use their cash then that's up to them. I'd say go for it if you can find that watch smith.

I'd rather be +2 than -2. If attaining perfection is your goal, then get it regulated. Otherwise, there's a reason why COSC standards are +/- 6. In the end, do what makes you happy and as far as I know, opening a watch for any reason doesn't void any Omega warranty that I'm aware of. If someone has evidence to the contrary in writing directly from Omega, then please correct me if I'm wrong by posting a link or copy of this specific warranty violation.

if only they could make the Coaxial movements a lot easier to adjust(like standard swiss lever movements) we could do it ourselfs on a trial and error base(you know turning the screw, let it run a day, readjust) untill it is spot on +/-) a day.

I bought a coaxial watch because i thought it was superiour to the swiss lever type(which it is)
if i would have known then what i know now i might have gone for the standard swiss lever because it is really easy to adjust yourself.

to give my bold opinion.
Yes +2 a day is better then most people have today. But then again a po8500 is a superiour movement so it should perform better then the standard 2500c movement.
So taking this into account i can feel Steve's pain.

Go for it but really take it to an expert(Omega Boutique) because those coaxials are easy to ruin(read the stories about movements getting their amplitude ruined)

to add something usefull.
My PO was repaired a couple of months ago.
the callibration specs go from +2 to +6
However it is Running +/- 0 a day on my wrist. +1 glass down -1 glass up.
My point. it seems that whatever they adjusted it to. it runs differently on your wrist.
So to get those +2 down to +1 or +0 it seems really dificult.
The only way to do this is to put the watch on a callibration machine, do a readout and adjust the watch so it runs -2 from those callibration specs.
This is normally not the way they will adjust a watch.

My POLMLE runs fast, my POXL 2500c runs slow. When the XL goes for a service, I will try to get it better.

My 2012 Explorer 1 runs perfectly. Never had that before. I hardly wear it, maybe it will worsen with wear!

I sort of understand as my 9300 is beat by my two 2500Cs quite easily. All well within COSC.

Where the OP is being a bit of rude is defending the silliness of this and being snarky.

If a non Omega dealer opens it the warranty is over, If you have a boutique give it a shot make sure you get documentation that they opened it and preserved your warranty.

Very interesting subject! I didn't even know what "Fettleing" meant until I read your post.

Personally, I wouldn't start messing around with a new movement that is only +2 sec./day, or any other that is well within COSC standard. But it would be interesting to hear about how it works out if you go ahead with it. Maybe it's not for everyone, but doing what you like with the movement is all part of the fun for you!

Mine, which I got about a month ago, has been consistently +3sec/day, but that is wearing it only on Sat and Sun. This long weekend, I have had it on constantly for 3 days, and now it's down to +2sec/day. I have never had a brand new movement this accurate.

The movement has evolved a bit since it was introduced a few years ago. I had rge size AT then, and it was not nearly that accurate. However, still within COSC spec. I sold it because I preferred that midsize, which I have now.

Keep us posted!

Cheers,
Carl

Not sure why everyone is getting so worked up about this, but if OP is unsatisfied with his PO's timekeeping, the best bet is to take it to one of the Omega Boutiques in London and ask to have it regulated. Some OB's have an in-store watchmaker, so OP can call ahead and find out which OB can regulate it on site. If they charge him for the privilege, so be it.

Pretty sure New Bond Street has in-store watchmaker. Still think your being a bit over the top regulating a +2 day watch though. Regulating a watch to aim for -/+ 0 runs the risk of it coming out a - a day. If your willing to run that risk then go for it, but as my Dad always used to say 'if it aint broke don't fix it'.

The problem with this thread now, is that poor Steve has backed himself into the stupid corner, he's coming out swinging, not connecting, but he's trying.

Maybe we should just applaud his impossible dream, it'll never happen mind you, but, God loves a trier....

Ive always been a trier, funnily enough due to me waxing the motor and all the cleaning rubbing the car its gained +1.5 in the last 24hrs!! I will give it 4 weeks for the movement to settle down and Ring Bond St tomorrow dont ask you dont get?

This is becoming quite an entertaining thread I must say, and Steve, I have to applaud your tenacity, and i mean that. Despite most suggesting to let it be, it sounds like you know what you want and will make it happen. Good luck and I hope the results are all positive.|>
ps - You waxed the motor of you car(which by the way looks super well cared for) ? Do you drive yourself crazy on occasion?;-)

As a fellow tinkerer and OCD car cleaner, I absolutely sympathize with Steve.

I just regulated my seamaster to +1.25 seconds per day because +3 was too much for me. I've even tinkered with cars that were purchased that day. I just don't think I'd open up a brand new watch though. I'd give it a little longer.

I'm more or less in the same situation. I have a ten month old AT 8500 which is exactly +4.5 secs off per 24 hrs. It's very stable though so I can't keep thinking of how accuate it could be if regulated just a tiny tad.

What bothers me is that with the 8500, being a new state of the art movement and all, I need to set it a minute slow in the beginning of each month and in the end of the month it will be a minute fast, so not only do I need to tamper with the crown on a monthly basis I also don't know what the exact time is at a given point, all this while the 8500 has all potential in the world to be super accurate.

This is especially annoying when compared to my 3570.50 Speedmaster which is dead on, I'm able to balance it out by different rest positions so I get exactly +-0 over time and only need to set the time twice per year.

I honestly believe, and expect, the 8500 to perform better. So silly or not I'm very tempted to have it regulated for just 4.5 secs off.
