Rolex Date - Authorized Dealer Can't Repair, What Are My Options?

[Mr. Twist]

I have a Rolex Date that I got from my dad about 10 years ago. He got the watch in 1970 and the serial dates it back to 1968. He had the watch serviced about 12 years ago by a jeweler who did not have access to official Rolex parts. The crown is an unofficial crown (it's obvious because it doesn't have the Rolex crown logo on it) and there may be a few internal parts that aren't official Rolex parts either.

Lately the watch hasn't been holding a charge well, so I went to a local authorized Rolex dealer to get it serviced. They told me they can't service it and Rolex can't service it because the watch has some aftermarket parts. According to the dealer no Rolex dealer can touch this watch again now that 3rd party parts have been used and they cannot replace the aftermarket parts with official Rolex ones.

What options do I have at this point for getting it repaired? There seem to be a number of unauthorized places that will repair it, but I'm leery of going to one after what happened last time. Is there any way to get it repaired with official parts?
