Agreed. It's a cheap and easy health check if you don't want to commit the time to knowing the real rate. I used to have a timegrapher and sold it. I spend my days at work designing and measuring clocks and frequency references for aerospace applications so it felt a little too much like work to be a hobby.

This is a real man's timegrapher measuring ~6 femtoseconds of RMS jitter. I paid $280,000 for this box.

Wow that’s some serious machine!

Any way I generally prefer watches run a bit on the faster side but I can easily deal with this. I rest DU over night and it’s on wrist for about 14 hours a day. I’m quite active as well so the arm gets a lot of movement. Haven’t put it on a timegrapher yet but I would imagine on there it’s right at -1 a day. From what I’ve gathered from post on here a good bit of 32xx movements seem to be regulated on the slow side.

Your 124060 has the 3230 caliber installed. Plenty of timekeeping measurements for various 32xx watches are discussed here:

My timegrapher rates, amplitudes, and precision measurements along the entire power reserve (for 6 different watches) you can find here:

A simple sketch to illustrate the difference between accuracy and precision:
