··Ash @ ΩFYou sure that last one's leather? That means the strap for the 45th anniversary Speedy still isn't listed there
alberto: I notice the same behavior on my new Omega Mark II (2014 re-issue), which also contains cal 3330.
My only other chronometer up to this point was the classic hand-wound Moonwatch, which always worked perfectly.
So I was quite surprised (and worried) when the cal 3330 stopped completely for the first time upon starting the chronometer.
It happened more frequently on stop-and-go usage, without resetting in between. On my Mark II, every 30 to 80 stop/go cycles, the issue reappears.
I passed it to Omega Vienna and got it back after 3 weeks. No change in behavior.
As archer said, it is probably the heritage on the horizontally coupled 7750 (or 7753, which has the quick date adjustment). We probably have to live with it, but I am definitely not happy with the situation.
Last week I bought the Apollo 11 45th Anniversary Limited Edition of the Moonwatch. This helps me forget about the issue ....
I can't say for sure what caused the watch to stop when the chronograph was engaged - it happens sometimes and as long as it doesn't happen again I think you are fine. My wild guess would be just an alignment issue between the chronograph runner and the oscillating pinion - peak of one tooth landing on the peak of another by chance, and causing things to stop - again just a guess. It's part and parcel of a horizontally coupled chronograph.
With regards to the small seconds, well certainly they are not independent from each other - it's all driven off the same mainspring, and if some sort of interference stops the chronograph, it will stop the whole watch., so that's perfectly normal.

Hi Archer,
I have same issue with my hesalite Speedy Cal.1861, the watch suddenly stopped when engaging chronograph after press stop and start button about 20-30 times, it happens quite frequently. By this frequency, do you think that would be the alignment issue as you said? or another issue that I should care about? is there anything broken or damaged?
How old is it? When was it last serviced?
Hi, thanks for your quick reply!
It since about 2000s, the series number is 77xxxxx. I got it used one, so I'm not sure when was the last serviced.
Updated: I have tested and I think it happens more when lower power. When it is fully wound, I almost not seen the stops anymore.
I think that needs more test. Do you think that is a normal power reserved issue?
I think it needs a service. Oils dry out you get wear... every 5-8 years or so.
