Also if a MR watch would bring me great pleasure for a long time to come is a key factor if to buy one or not. From raising this question I learned many things. One is that you might not get the sound from a service that you had anticipated. Expensive service is acceptable if it does the trick but very enoying when it does not. I know from experience with VC service department.
And the fact that several of the posts here talk about getting the watch back from service with a sound that you had antipated and payed for has mad at least me reluctant to buy myself a MR.
