Rolex Second Hand Stuck; Winding makes it go Backwards!! Help!

[Melanotaenia]

Hi Everyone

This is my first post on these forums. I have a Rolex Explorer II (not sure the year or model right now as I don't have the paperwork in front of me and I have had for well over ten years).

About two months ago I noticed that the ticking had stopped witht he watch (I kept it on a watch winder when not in use). I found this odd because it was being wound on the winder, so I take the Rolex out and wind it, give it a couple of shakes, and the second hand tries to advance but just sticks (you can see it trying to advance but it doesn't). If I wind it a little more, the second hand will actually begin to go backward for about ten seconds and then stop.

Right now I am a little low on funds so I am waiting on getting it serviced, most likely after the tax season, but I was wondering if anyone on here had any similar experiences with their watch and if so could you lend some insight as to what is going on with my watch?

Much Thanks!
