Hey. I recently purchased a used 9 year old example of an Omega Speedmaster Professional 3873.50.31 'sapphire sandwich' which I managed to get a good deal on, however when i asked the seller about it's servicing he stated that it had not had one nor will it need one any time soon as he knew many people with calibre 1863 movement speedy's who have never had problems with them. I've decided to go ahead with a service but am unsure of a reputable watchmaker to carry out the work.I have a few quick questions for you guys, How long does it generally take for a full service and also what kinda damage am i looking at price-wise? Nearest one to me acc to the Omega website is the Omega store in the Trafford Centre, is it best to stick with going direct to omega? Many thanks in advance for any responses, Chris.
