I'm another victim here of RSC rejection for my 6512. They wouldn't even want to do a clean and oil on the pretext that the parts inside might be brittle and break. Seems like very 'good' PR telling a customer their bulletproof watch will be brittle one day and not something you can keep running for more than 30 years. But I guess their hands are tied to process and policies.
My only gripe is that not too long ago, a similar watch was accepted for service at the RSC in NY. Caveat was that they wouldn't guarantee it against waterproofing.
