Spirate regulation system

It sure seems like they keep pushing to improve accuracy and stability, when it seems pretty standard to just be “good enough”.
Beyond good enough for me. My speedmaster 57 9906 runs +1 SPD on average, crown up at night it loses it. Ridiculous accuracy! My 300m 8800 is + 2 spd or less per day.

Not really sure at this point how spirate would benefit me on a practical day to day basis for the additional expense?

Spirate's key technical benefit is being able to look down on Rolex superlative chronometer owners for being 2 s/d less accurate. 😜

I don’t know how this is possible, but I have the Speedmaster ‘57 which doesn’t have the Spirate system but is the 9906. I synchronized it with my iOS clock on the 14th and so far it has only advanced 3 seconds over the past 11 days. I am going to try toolwatch.io and see what that says.
Same experience here. Been running almost non stop for a year and I’m always +1-2 seconds over atomic time (total..not per day). Mine gains around 1 spd on the wrist or laying dial up, then crown up at night it loses it. So I’m utilizing positional variance…but still…ridiculous accuracy!

Glad to see your post because I have been wondering if mine was just a freak stroke of luck. My favorite watch and it gets a ton of wrist time. IMO this reference is very special, unique, and underrated.

I would only change one thing, trade the original 1957 style lengthy lugs to some sweet twisted lyre lugs. Logically I know this would not be true to the original so snowballs chance in hell of it happening but one can dream. My wrists are just under 7 1/4 so the longer lugs fit, but I think the twisted lugs would look fantastic.

I was surprised to see the actual deviation on the metas results of 2.3s/day, rather than just “pass” for being less than 5. That was when I started wondering about the spirate, if it is really that much better? I’m sure it is, but I more than pleased with my ‘57. This is my first mechanical watch and I’m having a hard time looking at other brands because for the price it seems they are a great value for the quality and accuracy.

The bar is set high for your second mechanical watch!

Yeah I realize that in hindsight 😀. I’m hoping I can keep myself satisfied for a while by just getting some different straps, but I’m sure I will want to get something else at some point. The ‘57 covers a lot of bases IMO though.

From 10 March, my cal. 8800 Seamaster is +0.1 seconds. It's fluctuated a lot from there being worn, not worn and rested in various positions, put on a winder occasionally but that's pretty cool for a tiny mechanical engine.

Personally I’d question whether the 9900 is the most accurate current or recent calibre, do you know of anything to support that? Is there any analysis of COSC or METAS data available I wonder. It is an interesting point though, I wonder which is consistently the most accurate. Maybe Al or another accredited watchmaker would know. I’m not going to ping him though as he’s getting lots of vexatious requests for mundane info at present.

One other point, I think the single barrel movement get you refer to is in fact the 8800, the 8600 is a development of the double barrel 8500. Omega didn’t make it easy when they named these!

Thank you for the corrections!
As you point out, all are my subjective conclusions based on low numbers of ownership of the 8800 series calibers and 8500 calibers, plus hearing from owners directly or by reading on line. Just out of curiosity, are you questioning the 9900 because the old observatory tests awarded the less than a second deviating calibers, or because there aren't evidence?

As for 8800 series calibers, they were great on keeping time with a delta from six positions to be within 10 seconds, but they do lack consistency by flex of accuracy under same conditions. To phrase it in easier terms, they tend to change daily rates, plus 1 sec one day then minus 2 on another, then plus 4 on another day, whether being rested on exact same positions, or even on the wrist.
GO"s caliber 36 (i hope i got the reference right, the newer caliber on the sea-q pano date) using the Elinflex mainspring does amazing time keeping with a single barrel, and 3hz watches can be regulated to close to perfect timing, but the 9900 caliber architecture allows for less friction fluctuation (not friction in general, but fluctuation of friction causing timing deviation when run on the same torque), and the 9900 finally came back to the 4hz co-axial, after the first gen 2500 calibers.
Though not a scientific conclusion, 9900 seems to me the most worth the extensive regulation caliber, and for me, the 9920 kinda solidified my thought.

But then again, that could be just me.

What is exp2 ?

BTW, I just got my super racing, it's really amazing although checkered sub-seconds hands at times is difficult to locate

Apologies for this. I was writing with a different post in mind.

BTW to your btw, my super racing dial has a lot of dust like particals around the honeycomb angle areas under 10x loupe. Hows your dial?

Yeah I checked it with toolwatch.io and it says +.5 seconds per day. I know it’s not as good as a time grapher, and I think it might be even lower. As I mentioned I sync’d it with my phone on the 14th and as of today (the 27th) it’s about 4 seconds fast. Either way, it’s really good even without the spirate. I wonder what people are actually seeing with the super racing in the real world?

Mine is running on fractions of a second, on all positions.

Remember back then when we wanted to know how accurate watches were and we'd ask on forums? The replys would come in saying, my Tag is running 1 sec a day, my datejust is spot on etc.? It's all probably true, but that doesn't mean if you buy the same watch it will perform the same, much less the performance to be guaranteed.

Another point would be, were those stats noticeable on all positions, all year long.

The 9920 regulated witi the Spirate leaves only little room for beat errors amongst six positions, so the delta within six positions will become very small even with a flat hairspring.

I have only experienced my super racing only, but omega did regulate the watch so it will have plus average rating and minus average rating depending on the position, and when worn I tend to tilt the 12 oclock side downwards, and that makes it go a third of a second slow for around 18 hours on the wrist. When face up, it runs about quarter second fast for 24 hours.

BTW, I keep the chrono on.

I had to take it back as my Hour hand sort of bounces forward and then comes back to its set position after pressing in the crown from setting the time, bummed out.

Do you see this in your super racing?

Sorry to hear that. No mines fine, besides the gear tooth biting each other occasionally when manually winding, which all other modern omegas do.

I've been lucky with the jumping hour hand issues, but had multiple minute hand issues that after researching with the omega boutique tech people, most omega calibers, excluding the 18xx chronos and 321s, have wobbling play that are the design architecture, and some out of a bunch may be visible when shaken to one direction.

Anyways, whatever the issue omega service would do their best to adjust and rectify visible issues.

good luck

It’s a shame very beautiful watch but riddled with problems, I didn’t know about minute hand issues, can you share some links around this if you have?

Again, I'm sorry for your issue, and no, the minute hand issue is probably not as noticeable as the hour hand issues.

I wouldn't call them problems or flaws, but I would say they are caused by decisions between cost and efficiency against tolerance.
Your hour hand issue, though I would want to see it in person, isn't probably a mechanical flaw, but just caused by gears and springs having a little more play than other same calibers.

I'm sure omega can adjust it to your liking.

Thank you! I have took it back and waiting for replacement, let’s see, I do like the watch and I agree there may be play between gears.
