I have bought a vintage Omega Seamaster De Ville on the internet, and find it runs around 1 minute fast per day. I'd like to see if I can have it regulated to make it more accurate. I cannot do this myself, partly because I don't know how and partly because I lack the tools to access the movement through the unishell case.
Has anyone any views on a reliable London-based watchmaker or jeweller who might be able to do this work?
I have posted a similar message on the Omega forum, so apologies to those who have read this twice.
