Omega Cal 1337 Quartz Movement

Omega Cal 1337 Quartz Movement - I repaired (or so I thought) my first full movement from spare parts from not working movements. Everything seems to be running smoothly except its running probably 5-8 seconds fast. Any thoughts?

IIRC there should be a trimmer capacitor on the movement that can be used to tweak the rate.

That doesn’t seem to work…it’s actually almost 15 seconds fast.

I’m not a watchmaker but I’ve found that sometimes, changing the battery or just loosening the battery holding screw and re-siting the battery can have an effect on the running.
