My 50 year old Omega watch needed a routine service and adjustment as it was gaining. The Leeds branch gave me a precise estimate of cost, and returned my watch three months later in pristine condition and spot on timekeeping. The downside is that it was VERY expensive. I gave Watch Lab a try because of poor service via local agents and Swatch, in the past. They were expensive, but never got it right first time. Watch Lab were able to give a more precise quote, and gave a better outcome, but at about twice the previous price. The service would rate as very good, but its difficult for me to judge the value.
