Winding issue -- Need help/Advice

[Bonano]

To make a long story short, I was in europe 1 month and left my 16013 at home rather than take the chance of taking it overseas. It functioned perfectly when I locked it in my safe, but when I returned I discovered that it had problems manually winding.

Manual winding normally causes it to start after about 20-25 turns, but now it will wind until about 50-60 turns before starting, or will not start at all unless I give it a light tap. I can hear when turning the crown an audible 'click' like the spring inside is skipping over the shaft, and thus not winding the spring. It might be possible I pulled the crown a bit to rough when I first came home to wind it, and that is causing the issue. The movement itself functions perfectly, including the self-winding; it is only manual winding that proves difficult.

Anyways, I took it to my local Rolex authorized dealer/service place and explained the issue in detail. They insisted that regardless of what the issue is, that it would require them to overhaul my Rolex and pay the $600+ for the service, despite it having been serviced just last year.

Is anyone familiar with this type of issue? Is there any alternative than to have it overhauled/serviced? I plan on contacting the jeweler I originally purchased the watch from to find if the warranty is still present, but aside from this does anyone have any advice?
