RSC maintenance - worth it?

[DarkPool]

Hello fellow aficionados.

I'm the proud owner of an Explorer which I purchased from an AD and a 116660 Deep Sea I purchased a couple of weeks ago. Recently I tested the power reserve of the Explorer, which wasn't great at only 29 hours. Took it back to a RSC and the watchmaker gave it 50-60 winds, which yielded a less than impressive 32 hours this time.
I now winded it all the way to the clutch slip to see if I can get in in the low 40s, if not I will return it to have it tested. Since it's still under warranty there will be no costs involved. Different story with the 1166600. Since the availability of the Rolex tool watches is universally known, I decided to go for an 11-year old model in truly mint condition. Tested the power reserve and I got about 34 hours out of it. The thing is that after a full wind, I wear it for one day during 12 hours, the day after that, I wear it for say 8 hours and the morning after it usually will have stopped. Given the age, it just surpassed the recommended 10-year service window.

Since I don’t know the service history (the vintage dealer gives it a brief revision), I’m considering to go all out and have the full Rolex service which comes with a hefty price tag of course. The dealer I got it from also works with an independent watch maker at a lower cost and a quicker turnaround time.

What’s your experience with the RSC service? Worth it? The main reason for me would be to increase the power reserve and exclude any problem with the auto-winding mechanism.
