Simon Freese is an often cited recommendation, he recently also started setting up an auto shop.. ..oh wait....
OK 3 responses 0 recommendations so far. looking promising Legit question I thought presuming there are good and bad in most industries..... I shall await further responses in anticipation!!!!!
Another vote for Simon Freese. Top bloke. He was at STS (Swiss Time Services) for years as the workshop manager. He set up on his own a couple of years back. If it’s anything vintage Omega he’ll be able to sort it out. He is busy and you’ll probably have quite a wait but it will be worth it
Is it modern, or vintage @kevinlesser ? In Essex, you have Simon Freese and Swiss Time Services. Down in South London you have James Harris at Harris Horology (he's ex-Omega). If it's modern, there's no harm in getting a price from an Omega Boutique either.
