Hi folks, I finally bought a new Speedmaster Professional (ref 311.30.42.30.01.006) a few days ago. When the chrono is running, the minute counter completes its advance to the next minute when the second counter is at around 59.4 seconds rather than 60 seconds. Is this normal? Do others have the same thing happening? I contacted Omega, but I don't think they understood the issue, as they sent me a link to a YouTube video about how to operate the chronograph - not very helpful. I'd be grateful for any advice, as I don't want to pester my AD if this is expected behaviour. Many thanks, Graham
Yes, this is totally normal... it’s been discussed quite a few times here. Omega wouldn’t consider that behaviour a serviceable issue. Mine does the same thing.
Per Omega... "After fitting the hands, check that the minute recorder hand jumps when the chronograph hand passes over 12 o’clock." Should look like this...
Thanks for the feedback. The video is what I would have expected. Mine has jumped to the next minute at around 59.4 seconds, not 60 seconds. Hi Archer - do you think I should raise this as an issue with my AD? I want to make sure I have a watch within spec.
The watchmaker can regulate this. But is it importend ? My Speedys are 59,5 and 0,5 Seconds over to jump in the next minute
Just want to put it out there that mine does the same thing. And as previously stated, this has been discussed before and the general consensus was that most people's watches did it...if I recall correctly.
Funny how that works. But don't forget, you can see the glue that holds parts of a Ferrari F40 together...
So, because you aren't able to read the minute recorder for 0.6 seconds out of each minute, you consider the timepiece imprecise? Sounds like you need a Patek.
It's completely up to you - in my view despite everyone saying it's "normal" it is not. It might be a common fault, but it's not the way it should be.
Thanks all for the feedback. So the summary is it's common, but it's not right. I'll see what the AD says. Thanks again.
I think I misunderstood the OP. I now read that he said the minute recorder "completes" it's travel to the next minute at 59.4 seconds... I thought he was saying that it began traveling around then, which happens even in the video posted, and that the OP was concerned with the fact that it doesn't more instantaneously jump to the next minute. Sorry if we unduly jumped to a conclusion there @grahamg. My minute recorder does complete its travel right on the minute.
@gdupree - yes, it completes before 60 seconds - I don't mind the fact it takes time to travel, it's when it completes that's been bugging me.
Kind of hard to tell exactly, but I think my minute counter jumps in the last second, maybe 59.6-59.8. I can't imagine how that would be a problem with any casual timing I'd be doing. Had my Speedy since February, I used the chrono function for the first time at last weekend's MotoGP in Austin. I was able to time laps within the same second as the official transponders, that's certainly close enough for a handwound mechanical watch.
I guess since it's a jumping minute it shouldn't be a real issue as long as it's consistent. A sweeping minute, on the other hand (pun unintended), would obviously accumulate errors especially for very long timing runs. But this isn't a COSC-certified movement either and mine is 6.5 sec/d fast, and although I know it's the chrono minute hand that is being discussed, I reckon the good old "what's good for the goose etc.." holds true here. I also just bought the hesalite version very recently and the OP's post prompted me to check, and below is the result (apologies for the poor photo quality as those are screenshots off a video clip). So it does jump at 59.6s and I'm taking it as within tolerance. That said, I'm curious what the OP's dealer will say about this and would greatly appreciate a feedback here. Many thanks!
