Dial up for the entire test
It has a Co-Axial movement ref 8508.
It has left a very interesting and totally different Trace for us all to see …….
The trace VERY clearly shows that as the Amplitude decreases over time the Rate increases and as the Amplitude decreases the rate increases.
This is very different to Rolex watches. It is the opposite almost.
The timekeeping was pretty good also with an x of +1.6 spd
The beat error was 0.0 ... Outstanding.
In real world testing on my wrist, My watch gained about 1.5 seconds a day.

Hey Rolex is like this too. I have four 32xx watches now. When they are running I. Spec they do gain a bit of time as the pr runs lower and the amplitude drops. This is because the oscillations are at tad quicker.
The issue is as the problem manifests the drop in amplitude is because of increased friction not because of power pr. Hence it slows down.
For what it’s worth my nomos shows the same speed up behaviour too.
