Others have chimed in already, but I just walked in and had mine regulated while I waited. I'm sure you will have no problem dropping something off for a full service. They are really nice in there. I had a great experience.
Can someone clarify the current RO lineup available from US ADs as it relates to sizes? I'd love to put on both a 15300 and 15400 and compare the two sizes at some point, but if I'm not mistaken, the 15300 was discontinued? You guys an AD might have one of each but the boutiques probably wouldn't?
You (likely do not) remember my questions on the RSC in NY and having them take a look at my BLNR that was running quite fast. I popped up there, within 45 minutes, they had pressure tested, regulated to +1 second, and covered both services for free. I was on my way and a happy camper. Great result!
I've just heard that the NY center will honor warranties even if not the original owner. I'm not terribly stressed about it, I'd rather know the watch is running properly. If it turns out to be free, that's great. If they charge me, oh well. The warranty time frame is theoretically still valid, so we'll just see what happens.
