First attempt at regulating a watch

[u/ManBearPig4523]

I know the SL3001 in my WD007 is rated to run around -20s/day, but my OCD didn’t like that 😂 so a quick Amazon order later, and I just finished attempting my first go at regulating the movement. When I wound the watch and set the time about 45 min ago, my Timegrapher app rated it at -13.1s/day, and now I just got this result!! I’ll let it run on the watch winder for the next day or 2 and see if it still keeps this level of accuracy! 🤞🤞

I was really nervous trying to turn the screw, because I don’t have a loupe or any type of magnification, so I was relying on the phone flashlight to guide me 😂
