Rolex Submariner losing time

[Mike Lee]

I purchased a Rolex Submariner new from an authorised dealer in Great Yarmouth last May.

The watch was losing approx 6 seconds a day and I returned it in June to be checked over and the shop corrected the timing so that it was gaining approx 2 seconds per day which I found ok.

Last week for some unknown reason the watch began spontaneously to lose 16 seconds per day and when I spoke to Rolex they asked me to send the watch back via the Dealer for examination.

As I am likely to be without the watch for some 2-3 weeks I am very surprised that a watch of this alleged quality should behave in this manner and I am obviously worried that it may re-occur.

Can anybody advise me why this would happen - is this common with Rolex and if it happens again within the warranty period should I ask for a new watch?

Any advice would be greatly appreciated.
