Monobloc Watch Battery Replacement Norfolk

[Puddenchucker]

Can anyone please suggest/recommend anywhere in Norfolk that can replace the battery in a watch with a Monobloc case?
(That's the type where there's no removable caseback, so the glass & dial has to be removed to get at the movement).

I used to take it to the place in Bagleys Court off Pottergate in Norwich, but understand that that's now closed.

The watch doesn't need to be pressure tested (not a divers watch) and is not of great monetary value, but does have sentimental value to the owner.
So far, I've only found one place that may be able to do it and they want approx 2 weeks and £75. (Presumably, they'll be sening it elsewhere).

Thanks
