Watch Lab in Glasgow. This is the worst service I have ever received. I put my RADO watch into the shop for a battery and ended up paying £69 for a battery and re-seal. I returned 2 weeks later with the watch to be told the battery was dead. When I returned an hour later to pick it up Callum told me it was in poor condition and that the battery was fine. He proceeded to test the battery in front of me (it could have been any battery) to say it was working, after the person who took the watch from me saying it was dead. Callum then proceeded to say that there was something wrong with the glass and that a service would be £250, I thought he must be joking. I advised him that when my watch was handed to him 4 weeks ago and he went over the watch, noting scratches etc. on the outside, there was no mention of the glass on the front when I handed him the watch and he checked it in front of me, nor when I picked it up. A heated discussion took place where I advised Callum that I would not be accepting that the watch now needed all this work, where he said to me in front of 2 other customers "you're getting on my nerves now so please leave the shop". I advised him if that was his attitude, he was in the wrong job. I have written to the Watch Lab as I am now £69 out of pocket and have a watch returned to me in worse condition that it was 4 weeks ago. If I don't hear back satisfactorily with 1 week, then I'll be taking this to Trading Standards
