Thought I'd start a fresh thread.
So it arrived from the Omega Boutique today, took about 10 minutes to fit to the bracelet, 4 screws basically and that was that. Glad I decided to go for it and ignore the advice from Lunns in Belfast.
The clasp itself is bigger and longer so I had to remove another link to allow for this but very comfortable on the wrist.
Great service from the Regent St shop.
