I haven't done much hairspring work but isn't the terminal curve incorrect? -
As @Knebo suggests, the second coil could be hitting the regulator pin. I also think the coils could be bunched up on the other side to the stud and touching. I agree with @Nucejoe that it would be sensible to repin the stud nearer the end. It looks odd that there is so much hairspring protruding past the stud. What I'd do is remove the hairspring from the balance and repin the stud near the end. Then install just the hairspring back on the cock. You can then see if the collet is sat over the jewel hole, and make adjustments as necessary. (Depending on your skill levels, repinning studs and tweaking hairsprings can be tricky, but it's a good chance to practice and improve)

This is not making your watch run minutes fast, but I would unpin the hairspring to repin the stud at the most end point of hairspring. When installed the coil looks bad. I'd be concerned if tg showed this watch running accurate, concerned that my tg might be feeling unwell. 🙃 Rgds

The photo I posted was just an example to show how the camera connects to the microscope. I used to use a setup similar to that but I now use a mirrorless camera. When I did use that type of setup I didn't connect via USB, I just saved to the micro SD card.

Thanks for the reply Knebo. Nice catch about the bumps under the balance cock. I've seen those on the main plate in other watches but not as was done here. I'll do as you suggested and see what comes of it.
