New SMP 300 overnight position

Hi folks, I hope you are doing very well.

I have new Omega SMP 300. Unfortunately it started losing time and I'm not sure what to do with it.

When I first started using it was gaining time:

12.11.2024 16:00 -- +0 sec (dial up)
13.11.2024 20:12 -- +2 sec (dial up)
16.11.2024 07:52 -- +9 sec (dial up)
18.11.2024 20:50 -- +17 sec (dial up)
20.11.2024 15:06 -- +24 sec (dial up)
22.11.2024 11:00 -- +28 sec (dial up)


Now after new year (I guess movement has settled down) and no matter how I store it overnight it is constantly losing time:
04.01.2025 14:17 -- +0 sec (dial up)
06.01.2025 08:21 -- +1 sec (dial up)
08.01.2025 06:14 -- +1 sec (dial up)
09.01.2025 10:45 -- +0 sec (dial up)
10.01.2025 12:38 -- -2 sec (dial up)
11.01.2025 12:11 -- -2 sec (dial down)
12.01.2025 12:11 -- -3 sec (crown down)
13.01.2024 05:53 -- -4 sec (crown up)

It is fully wound at any time, I move a lot and there are zero other issues with my SMP. If it was gaining time I wouldn't bother. Just hack the movement on the weekend and it is done. But with losing time it is quite a frustrating experience for me.

Here are my METAS values:

Average daily chronometric precision of the watch 1.6 seconds/day
Deviation of chronometric precision in six positions 1.4 seconds/day 0 to 14 second/day
Deviation of chronometric precision between 100% and 33% of power reserve 0.3 seconds/day

Should I send it to Omega for regulation?

Thanks and have a great day

I purchased my Speedmaster Racing new in November 2021. For most of the time I've owned it, it consistently lost 0 to 1-2 seconds per day. It would occasionally gain a second or two. My understanding is that the master chronometer movements generally gain time. The test standard is 0/+5 seconds to 0/+7, depending on the movement. It was frustrating for me because it wasn't what I expected, and I, too, considered whether I should send it to Omega. But I realized from an accuracy standpoint it was extremely consistent. I just set the watch a minute ahead, and rarely ever had to reset the time. I had to reset it more often from DST changes than the watch losing too much time.

Then, all of a sudden last year, around early November, it started consistently gaining time. I recently reset the time on 12/31, and over the past 13 days it has gained 15 seconds. I'm happy it changed, but I have no clue why. Nothing happened to the watch. All of that is to say that as long as the watch remains extremely accurate and consistent I'm not sure it's worth sending in, and it still may change over time.

If I'm reading you right, from 9/1 to today your watch lost 4 seconds over 134 days. Those are not results I'd mess with, personally.

Many thanks for the reply and congrats on a great watch!

It is METAS ceritfied so it should be plus 0..5 seconds averaged on all 6 positions.

My problem is that in my certificate it is fine, but in real world usage it loses time in all 6 positions, no mater how I store it overnight. I have tried all possible and impossible but starting from 22 November 2024 it constansly loses time.

Thanks

I'm not sure what the allowed deviations are in all 6 positions. I do know the watches are tested in six positions over 4 days, and then the results are used to calculate a daily average. My watch's daily average was 1.8 seconds per day. METAS' test limit is an average of 0 to 5 per day.

They also do a test in six positions to measure "chronometric precision", and calculate the deviation between the two most extreme results. Mine was 3.9 seconds per day. METAS' test limit there is 0 to 12 per day.

Seems to me that somewhere in all those test results, the watch is losing some time.

Do you store your Speedy in a particular position overnight (e.g. dial up or down)?

It's new. Forget about it a bit. Enjoy it. Let her live her new watch life and if in a year it's still loosing time, maybe sent it if you really are bother by 2 second a day.

What impact does this have in your life? Are you constantly late for meetings by a few seconds?

I would stop checking it every night and not worry about losing a few seconds a day.

Dial up, all the time.

It is more psychological effect. Big expectations initially, given the fact that my older and cheaper Tissot Gentleman is +3 SPD from the same Swatch Group.

I would prefer my SMP 300 gaining not losing time, that's why disappointment.

Yeah, I will set it 1 minute in advance and let movement to break-in a bit more. So from your experience it is +-12 months for a new movement to settle down, right? As I mentioned before my Tissot Gentleman after 5-6 months is +3 SPD without any "overnight placement magic". Out of the box it was +5-6 SPD and no time loss at all

No, if it's Metas/Cosc certified it isn't logical it would be running out of spec when you receive it and needs to break in for a months.

I would advise to test all 6 positions 24h (wind it before you start in a new position and check deviation 24h later) each and see what the average is.

I have three new 3861s, stored dial up. I'll set them to NIST time and wind all three. 67 hours(!) later the white one is 15 seconds slower than the other two, and it has been rebuilt by Omega already. Does it stress me? No.

Like I said, I had the same feeling for a while, thinking my watch should be running ahead instead of behind. But, I ended up not minding because the timekeeping was so precise and consistent otherwise and I didn't want to be without my watch (or have it opened/serviced unnecessarily), so I got over it. The fact that it finally started to consistently gain time like I expected is great, of course. We'll see if it stays that way.

That said, I'm not you, and you seem like it is fairly important to you. Talk to your dealer or Omega boutique about it, and if you don't mind parting with it for a while send it off.

Sure mate, whatever. For me it will be a big deal though

I will check fully wound with Weishi 1000 tomorrow. Not sure if it detects amplitude on co-axial though.

I don't believe the Weishi 1000 can measure the amplitude correctly on co-axial. Also, make sure to set the lift angle to 38 (or 36 if it's an 8806 movement).

If it's a big deal for you and it's under warranty, then have it regulated of its not running within spec. It's your watch; you're the only one it should make happy.

Had a SMP recently that lost time across most positions. Eventually it was losing from to 6-9 spd and worsening from week to week, despite full winds each day. At that point I contacted Swatch service and they had me send it in. Tested it, then ran it on their simulator unit (sic) and noted that it was losing time over 5/6 positions..

Regulated and returned it is gaining around 1,7spd. Had it not started to lose dramatically and consistently I’d not have bothered. Best advice I can offer is to track it for a week or two. Then decide if it’s worth the hassle and risk of seeking service. Best of luck.

Was it some older model or brand new from factory if I may ask please?

That is very interesting, is something I can do with timegrapher? Never heard about it

Thank you mate, much appreciate it. I'm not a watch maker, thus not sure if I should pay attention to amplitude. From what I understand if it is bellow 270 then lubrication is needed. I do expect though that my brand new watch is at least good lubricated at the Omega factory. Or is Omega QC is so bad nowadays, that I can't rely even on this and should monitor apmplitude too? I guess I need Wishi 1900 then, not 1000
