Rolex 3135 amplitude

[JoePublic]

So I just bought my first Rolex. Its used.

And ive put it on my Timegraph

Fully wound face up its +5.1sd  210 amplitude and 0.7ms

After 24 hours of running hanging position crown down its +3.9sd 180 amplitude and 0.2m/s

Dealer says this is normal for a 3135

Dealer receipt says it ways recently serviced by a rolex specialist May 2019

Am I being paranoid, is the movement ok or not ?

Can anyone put my mind at rest.

Cheers

It should be between 270 and 310 degrees.

I agree with OH (the master). I had the same problem with my old 1980 Seiko where it was supposedly serviced 10 years ago and I brought it home and it had very poor amplitude. At the time I knew zero about watches and this event in fact started me on my adventure. So the watch either was poorly cleaned or they did not replace the mainspring (and it is set) or the balance mechanism needs work. I have also found that the balance jewels are often gummed up more than other jewels and perhaps the repairer did not clean the balance jewels or the hairspring.

All thoughts only.

jdrichard is right saying due to poor cleaning or bad mainspring. It would surprise me if the watch hasn't been cleaned recently.

Thank you for the answers

So am I correct in thinking there definately is an issue with it. Either its not been serviced, or not serviced to Rolex specification, or serviced but other issues like the main spring not sorted ?

I would say so.
