servicing a rolex - what are my options?

[jasonpage]

A year ago I bought a new Sub from an AD. From memory, my watch came with a two year guarantee. And (I think!) the dealer recommended getting it serviced every five years or so. First question: is this good advice? Does a service every five years sound about right? I wear my watch pretty much all the time. But I have an office job so it isn't really exposed to anything too terrible.

Second question: when it comes to servicing my watch, what are my options? I understand that I can send it back to the Rolex factory (presumably I do this via my AD) for an "official/authorised" service. I believe that Rolex will guarantee a watch serviced in this way for one year.

Another option would be to go to a "Rolex accredited" repair centre e.g. http://www.time-repairs.com/watchrep...PriceGuide.htm - presumably "accredited" in this context means that they use genuine Rolex parts. But does it mean anything else? Are "accredited" companies vetted/approved by Rolex. It's not very clear!

I would apprecate any and all advice members can offer on this subject. Thanks
