In the position it's being measured, the watch . . .
. . . is gaining nine seconds per day at that moment. The movement's amplitude is 312º, which is a little on the high side, but not necessarily an indicator of a problem. The beat error is 0, which is as good as it gets. And the lift angle is 52º.
Are you measuring a Rolex?

Who knows how to read this thing???
Talk to me like I am a baby and is this acceptable? ...

Got it thank you
Nope this the IWC Portuguese with 7750 in it. With resting overnight it’s actually around +12 a day
The lift angle of that movement should be 49º. There should be a means . . .
. . . of adjusting the tester to reflect the correct lift angle. I asked if the watch were a Rolex as, from memory, most auto Rolex movements are supposed to be measured at 52º. That may be the default setting on the tester. The movement should be tested ...
Thanks for the tutorial
I will mess with it later today. I bought the watch pre owned and it’s 1 year old in mint condition. I noticed it runs fast but was not sure if that’s how the movement should be. I had this thing laying around the house and figure why not test it!
So I changed the degrees to 49
I tried different positions and they are all around +8/9 and the beat error goes from 0 and sometimes .1 ...
Notice how the amplitude dropped to 283º . . .
. . . when you adjusted the lift angle? That's a reading I'd expect from a modern movement in good condition. If readings in all positions are similar, then chances are the movement's in good shape. Notice the straight lines? That's another good indicatio...
+1 Cal 7750 has LA of 49deg. That instrument has a range of 10-90deg. If you wanna it to be within -4/+6s/d COSC then think of regulation and positions but as is...
that watch prob runs fast <5m/month. Adj it once a month and be happy - nothing wrong with it )
A the side it will be
it will be harder to read and then you give up and be happy with your watch.
I have one of these and I know how to interpret the data.
Unfortunately without knowing the lift angle the data is mostly garbage. I still can't find the correct lift angles for 90% of my watches. The rate error is how fast/slow the watch is running in s/day. The beat error is the amount of irregularity in the t...
Personally I wouldn't be happy with +9 s/day for any watch $1,000.
You have to do the tests in all 5 or 6 positions for which the watch has been regulated to get a real picture of the rate error. My Patek 5960 runs on my wrist at My GO Sport Evo runs fast in every position which is a pain because I can't rest it in any p...
Interesting
I have to say I could not care less of precision for my mechanical watches. It's true it is better to have them precise of only a few seconds a day, but I swap them so often that at the end of the day I don't care. When I want to know precisely the hour (...
There's a meaningful distinction between a watch that gains 9 seconds per day . . .
. . . and one that gains 8 or nine seconds per day in all four commonly measured positions. A delta of a second between positions is an indication of a well-adjusted movement, or so I'm told. And preferable to a movement that gains (or loses) fewer on the...
I just go by real life use cases
From a dead stop I wind the watch, hack it and synchronize and then wear it. No matter how I rest it or wear if I am ok with +3/4 maximum. So far Tudor, Rolex Omega, Grand Seiko, JLC have been pretty good to me. IWC makes some of the most inaccurate in ho...
