JLC Chronograph advice sought

I have 2 JLC Chronographs that are approx 4 and 8 years old. The automatic rotor has stopped winding the mainspring on both watches (I have read accounts of this exact issue on other forums). I can wind the mainsprings with the crown and they operate well. I am out of warranty on both and ineligible for a warranty extension on the newer watch for whatever reason.

My question is if I should send them to be serviced by JLC or use an independent shop?

Thanks for your time and thoughts. I am all ears.

I dont think that independents have access to parts. Did you purchase them at the AD? If so, then maybe they can help you out on the warranty issue, at least on the newer one.

Thanks for your advice, much appreciated. I will go the factory service route.

The prices are on their website. I am braced.
