Just Received Watch Back From RSC. Questions About What They Did.

[nsguy]

Hey friends, I posted a while back about some power reserve issues with my 2016 submarine (https://www.rolexforums.com/showthread.php?t=600735).

I decided to drop it off at the AD I purchased the watch from. They monitored the issue for a few days before noticing the problem I was seeing, then decided to send it off to RSC under warranty. They received the watch back from RSC, did their tests again, and said it's now ready for pickup.

I asked for the receipt from RSC and I noticed all it says under "Service Operations Executed" is "Check Movement". It's unclear to me whether they actually found an issue and fixed it, or just could not reproduce the issue and sent it back to me. Does anyone know if it's possible they did some work but "Check Movement" is a catch-all term for them? I'll be monitoring it on my end now that I picked it up and will see if the issue remains. RSC is closed today which is why I didn't just call them. Thanks.

Update: If I recall correctly when I was dropping my watch off, the service agent noticed that when winding it, it would never seem to hit any resistance once fully wound. I just tried now and I notice it hitting a resistance, so perhaps RSC did do something after all.
