A friend is needing this one completely revamped, pins replaced, stretch taken out and refinished. Its a 1503/825
I couldn't find anyone in Europe three years ago so MY's outfit did a good job on this poor old thing.
I remember recently reading about a fellow in the UK doing the vintage rolex bracelet tightening and could be he handles other brands. I can't recall if he is also a member here but his post was on TRF. sorry I don't remember his username but later today I will try and find him on that forum and post here if one else knows who he is and beats be to it.
