To RSC or not yet?

[big5safari]

I have a Submariner that's about 7 years old. It still keeps time accurately...maybe gains a second a day. What I have noticed in recent months are:

1. If I don't wear the watch over a weekend then it stops within about 30 hours or so. I recall it lasting at least a couple days in the past.

2. When I shake my left hand with my watch on, sometimes I can feel, and may be even hear, something that's similar to release of a wound spring.

I would think if one of the springs gave up its ghost then it shouldn't be able to keep time so accurately.

I called my local AD a coupe days ago and I was informed that it will cost ~$1100 to service my Submariner at RSC. What are your thoughts? Should I send it in to RSC or not yet?
