Movement 3185 accuracy after service

[rollee1]

I'm fascinated by the accuracy on new Rolexes.

The 3185 movement are time proven workhorses, with upgrades over the years. I read on post after post that they are just as fine and accurate, it is found in plentiful ExplorerIIs and GMTs.

After a full RSC service, can I expect the accuracy to be like brand new and holding time consistently?

Is +/- 2s / day an unrealistic expectation?
Does full service mean a complete movement rebuilt?

On another thought, how much of this is reliant on the expertise of watchmaker him/herself?
Even of they all hold the same accreditation and skill level, exact accuracy can be a shot in the dark?

Even a vintage Rolex can be regulated to +/- 2 secs a day or better, and kept spot on with overnight positioning. Even my Tudor Heritage Chrono will stay exact in this way for months on end. My newer Rolexes tend to gain two or three seconds a day after service, and are less responsive to overnight positioning. Good regulation by the watchmaker is key, of course.

My 92ish GMT II runs at -2s and is one of my most accurate watches. To your other point, I think of accuracy as consistency in the watch world, so the smaller the deviation the closer it can be regulated, which it may need to be more than once because they can time different on a machine versus your daily life routine.

Yup. It all has to do with the skill of the watchmaker and his/her ability to time the watch.

Should not be unrealistic to expect that.

My 16710 came back from RSC +3

Its reassuring to know that I can expect a high level of accuracy after a full Rolex service.

I found an independent watchmaker who is Rolex trained and works out of an AD, will have a word with him when I bring my trusty old friend to his hands.

I believe Rikki timed my Bluesy in at +.5

It is almost quartz accurate, very happy with it's performance!

I have my Rolex Sea Dweller overhauled by Total Watch Repair near LA in January. It is already two months now and is running +1 second per week. Sure, if your watch is regulate properly, you should expect that kind of accuracy from Rolex. If it is not, you can always take it back to RSC to regulate for free.

My dj2 was running -3.25 per day since new. A full service come back running 2.75 per day. I think it will slow down slightly over next 7yr and then be ready for next service. I am very happy.
