Omega 3220 Question

[anilv]

Dear Mark,

 

I'm glad that your starting a series on the ETA2892-A2. I have a friend with an Omega speedmaster reduced (3220) which runs inconsistently. It will run well for a few hours but suddenly will start to run fast.. fast as in 5 mins / hour. Starting the chrono and letting it run for a while will usually get things running normally.

 

I initially told him it was probably a hairspring problem and that the watch could do with a service. As I'm not too familiar with these movements (all I known is that they're supposed to be a pain to have serviced) I googled it and found a thread which linked poor running to repairers using the same mainspring as the non-chrono base movement.

 

Fine.. I can accept that the chrono will probably need a different mainspring due to increased power demands but most of the usual sources quote the mainspring as being common to both the the chrono and non-chrono. Your thoughts on this?

 

If the mainspring is a common part for chrono and non chrono movements, then it comes back to my original suspicion of a dirty/magnetised mainspring, perhaps the act of starting/stopping the chrono is sufficient to jar the hairspring enough to loosen/unstick the hairsprings?

 

Anyone come across this?

Did you fixed it ?

No drefhill,

It was definitely the chrome module as the watched behaved well on the timegrapher when the chrono was running but started to get erratic when the chrono stopped.

Told my friend I was not willing to work on it.

I had one of my own for a short while, that worked fine without any problems but the thought of future issues probably helped me decide to let it go.

All the best with your project...the cost in price will be high..make sure you don't exceed the value of the watch!

I have one with broken glass, water got in and it's rusted now, not working at all. Sent it to Omega for a quote, about 3 weeks later =>780€ for repair and service. Regular service i think is 620€ so that's and extra 160€ for parts, i was expecting more but it's still way to much for that watch and i also need a bezel so total 950€, they put a new case optional at an extra 1200€.
I've refused it, so now i'm waiting to get it back (told me about 2 weeks to get it back).
Once i get it back i'll try to see by myself more in details how much rusted it really is and see if i can find someone to fix it for not to much, also i believe Omega replace everything that got a bit of rust on it maybe a good cleaning would be enough. We'll see.
