Rolex Milgauss Problem

[Paper8]

Hi there,

I’m new to this forum.

My Milgauss is about ten years old now and I hadn’t worn it for a few months.

Few days ago I wound the watch and it worked normal, then during the day it suddenly stopped. No shaking or winding would get it working again.

I left it aside and today I shook the watch and the second hand started a little, then suddenly started going backwards.

Any idea what’s up …… how much do you think estimated cost of repair at Rolex.

Thanks

P
