ESA 9162 Tuning fork movement

[knutos]

I have two watches with the same movement not working. Eterna Sonic and one Omega f300.

I am looking for help to have these serviced.  Is it ok to ask for this in this forum?

I'm unable to answer your question, but I'm wondering if these movements are the same as or similar to the original Bulova Accutron movements?

These were made under license from bulova. But esa made some significant improvements. Anyone looking to undertake an overhaul would do well to dig up a service manual (available with couple minutes googling) and follow it. Service is quite different from a bulova. They are tractors and run for decades if not abused- like accutrons.

They will run once repaired. Yet mostly inaccurate. I got an omega and no plans to wrestle with it.

Thats good to hear, now I only need someone to help me servicing them.

These are really interesting watches some improvements over the Bulova. You can separate the electronic module from the rest of the watch. There's even a calibration device built inside providing somebody put it back where they found it. The biggest challenge of course is finding parts for these watches.

So interesting video at the first link. Second link in case you lose your mind and want to service it yourself. Third link interesting pictures of different tuning fork watches and you'll notice this person services these type watches.

Thank you for your kind answer, all above is known to me already, however I haven't been able to get in touch with the parson behind the site mentioned in link 3 yet.

So the first link is interesting You'll notice somebody is asking about the exact same person you're asking about. So on this discussion group he goes by the name of Silver Hawk Versus his real name of Paul. So the indication is if the contact page is open he should reach out to you as soon as he catches up with his backlog of watches.

Given at least some similarity to the Accutron, I wonder if someone who works primarily on those would be willing to take this one? Oldfathertime.com and accutrons.com are the two places I know of.
