Only deal with Seiko, they did a superb job on my grandfather's 17 jewel auto circa '71. The crystal on that was scratched to buggery (he was a gardener all his working life) and they asked me if I wanted it replaced. However, I just opted to have it polished as keeping the original crystal in place seemed important. I'm sure they'd be able to help you out.

oh cool,
I have my granddads old seiko... but the face has discoloured its in need of a bit of love.

Just had a bit of a google i guess its from the 70s. Anyone know of somewhere i can look/call up?
