Following the service work by Sean my JLC reverso gran sport now keeps excellent time and the automatic movement has the reserve time it had when new. The watch had not been serviced for 12 years and was running very slow. Sean clearly explains what he can do before receiving the watch, gives a straight forward assessment of work needed when he gets the watch and does the servicing work to a very high standard. Sean’s communication and web site are very impressive and interesting showing clearly what he is doing. Sean serviced my watch at a fraction of the cost JLC charges and much quicker, Sean makes owning posh watches far less painful when they need work. Sean is 100% recommended, I will be using him again.
