How is my 2019 GMT II running?

[smxy96]

I’d love to know if my watch is running well or in need of a service or a service coming up (how far away?)

It’s a 2019 GMT Master II.

Rate: +4 s/d
Amplitude: 262
Beat error: 0.6ms
Parameters: 28800

Will this need servicing?

Short answer no remember there are 86400 seconds in a day.

I would require many more details.

There are quite a few threads on the performance of this movement.

It’s running fast? Holy smokes … send it to the Smithsonian

Or Ripley's



Seriously OP, we need some better intel. As mentioned above there is no deficit of threads on this matter. When was the reading taken, right after winding, 24hrs later, just randomly having worn it? in what position, dial up, crown up, etc? Need some more readings, different positions, over some, even small, amount of time.

I’m not a watchmaker so take this with a grain of salt. What what I’ve always heard and personally observed is that a new Rolex or one recently serviced by a top-notch watchmaker should have amplitude approximately ~300 degrees when fully wound. On the other hand, once you get down to 230-240 degrees, it’s indisputably time for a movement overhaul.

Yours seems in the ballpark for a five year old Rolex, if perhaps a little low. Are you testing it on a decent timegrapher and manually winding via the crown 40 turns before testing? Newer synthetic oils last a long time so service intervals are longer than in the past. Ten year service intervals aren’t out of the question, at all.

Looking good! I does not require service or maintenance. Low amplitude or changing from gaining to losing seconds is the telltale sign that a service is needed.

300 is about the max you'd expect with an older 31xx movement. The 32xx runs at lower amplitude, generally speaking. It also has a different lift angle so you'd need to change the timegrapher settings to know exactly was the amplitude is.

As far as 230-240 being "indisputably" time for a service, keep in mind it depends on position. That amplitude range with the watch in a vertical position is totally normal for a 32xx (and again a bit low for a 31xx). My fresh-from-RSC 3285 does around 235 at full wind when the crown is down. It does 273 with the dial up.
