Can people please comment on the timegrapher readout?

[Classique Breguet]

Hello Fellow Collectors :0)

I just bought an older rolex 1500 off ebay for kicks and I wanted some who know movements to tell me if and where I should have the non hacking 1570 movement serviced.
Here are 3 pics from different positions on my timegrapher

Does the up to 1.5ms beat error mean it needs/would benefit from a service?
It runs from -6 to +4 depending on orientation, but it is the beat error I'm curious about.

I'm in the SF Bay area, where would people recommend I get it serviced if it needs it?

Please see attached photos

I'm not an expert, so I won't try to offer advice, but until some a tech drops by, check these out.

Can you run the tests again but with these parameters.

5 positions ... DU, 6U, 9U, 3U, DD
Clearly label each pivture with what position it is in.

Firstly fully wind the watch.
Place it on the timegrapher the correct way round (Crown touching the microphone).
Wait 15 mins.
Start measuring. 2 Mins in each position with 30 seconds between positions for stabilisation.

Take the photos as you go unless the timegrapher will give you a collective screen.

You have set the lift angle to 52 degrees ... I do not know if thats correct ... You do need to verify that.

When all thats done post the picture(s) and we can analyse them for you.

You need the X and D to get the true picture from the results.

Lookup Giovanni in San Francisco in the old Shreve building. His shop is formerly the Rolex RSC. And he still has the parts acct.

Some others will be along shortly who will also recommend Giovanni.

I don't think you'll find a watchmaker who suggests those beat errors are "good", but your timekeeping is actually quite good in the conditions you have measured. I think it comes down to what your goals are with this piece. If you want peace of mind given its unknown history, this would be enough reason to have it serviced. If you simply want to wear a vintage piece and aren't too stressed about perfection, strap it on and enjoy it until you see a more obvious degradation in timekeeping.

100% agree

It is going in for service
