Does hairspring on ETA 2789 just lever off ?

Do these types of hairspring on ETA movements (2789) just lever off (I know some Seiko can't be removed) - thought I'd ask before I risk damage ?

I've run out of adjustment to set it in beat, so I need to turn the spring.

I could turn the roller, but don't fancy pressing it back with the hairspring fitted.

Yes, it levers off like any other. Remember the hairspring levers initially act as wedges, they should be quite sharp, wedge under collet, then lever up.

Thanks. I found that, like tweezers, they are a tool worth paying for good quality. I have some Horotec levers which are great.
