·I do not think Omega will help. In the UK Simon Freese has the most experince now I think = http://www.simonfreesewatchmakers.com/
You can also try @wristpirate as Simon is sometimes at his boutique Tortoise Watches now. https://tortoisewatches.com/pages/london-boutique
The main issue is parts now, but I guess adustment is different, although warranty becomes a problem. Also I know Simon has a lot on currently.
Assuming at least a few folks here will have the same watch and will have troubleshooted the same problem.
Any other inputs would be much appreciated from the community.
