I found Gordon Of Horologica on line- I have an old carriage clock where the hands were sticking and it didn't keep good time.It hadn't been serviced for over 30 years. I emailed Gordon and he came across as an expert from the outset. I sent him the clock, he gave me a detailed overview on what needed doing to it, and that was it - it was an excellent experience and the clock came back fully serviced at a very reasonable cost. I am well impressed and have no hesitation in recommending Horologica. Service and experience like this is hard to come by these days!
