Choose Guest and Philips, as they were Tiso agents, to have my watch repaired. I was advised that they could send it to the manufacturers and cost would be no more than £180 regardless of any work that needed doing, as Tiso offered an all inclusive repair scheme. I left my watch at the beginning of January, rang the shop several times, hoping my watch would be ready for collection. Alas it was not ready until today 11th April. The staff were unable to tell me when asked, what repairs had been done, and didn’t offer to restart the watch and set it to the correct time. I had to ask the assistant for that service. When we disputed the bill for £193 when we had been previously told that that it would be no more than £180 we were amazed to find them rather vague with the answer. Knowing that Tiso do all inclusive repairs. The service at Guest and Phillips was not what we expected, and really wanted us out of the shop.
