Amateur regulation of SKX/7s26

[HobokenRolex]

My SKX 007 never kept very accurate time - it was maybe 3 min slow per day. Whenever I wore it, I'd just set it ahead by a few min. I would typically only wear it during the day for a few hours (and only 1-2 days per month) so it never bothered me. However, I figured that I could - maybe with luck - get it more accurate after watching YouTube videos on adjusting the movement. $30 in cheap tools, with a few attempts, and it's + 30 sec per day. I'm happy with that and had fun working on it. Here a pic of the movement.
