Hi Arron. Disclaimer: I am a hobbyist and not a watch repair professional, so take my advice for what it's worth. 1. I would say no. At worst it could lower the amplitude some. 2. It does from the top, but from the side it looks all wrong. It looks to me like it would foul the rest of the hairspring and cause it to stop oscillating. The Breguet overcoil should sit roughly parallel to the rest of the coils but on a higher plane. Yours looks bent in the opposite direction. 3. If the balance spring is bent near the stud it could push the whole spring off-center once the balance staff is in its jewels. 4. Unless it was very severe, then no. -
This will not work overnight it will take time brush oil on the hamer leather. Have you tried to move the hammers slightly away from the gongs.

Hi everyone, Facts: I'm working on a Hamilton 16s Grade 974 PW. Serial 2418945. Before doing a coa, the watch ran well in the dial down position. In dial up it would fairly quickly stop. There was a lot of gunk on the upper pivot and I figured that was the problem. After the coa, it continues to do the same. I went through troubleshooting using another thread on this topic. The only two issues I could find are 1) the spacing of the hairspring coils are closer together (but not touching) on one side than on the other side (I don't have a pic of that). but when I took the hairspring stud off the balance cock the coils are equally spaced all around. 2) The upper jewel (the one that sits in the balance cock) has a slight indentation where the balance staff pivots has worn it away. Other than that, the balance isn't touching anything, the hairspring lies flat, there is plenty end shake, and the pivots look good to me. Questions: 1) Will such a small divot in the cap jewel cause the balance to stop. I have no idea what the measurement of the divot would be. 2) Does the last loop on the hairspring look normal. 3) Why would the balance spring bunch up on one side, but be normal once removed from the cock. 4) Would the hairspring bunching up to one side cause the balance to stop. Thanks for any guidance you can provide. Arron.

I keep working on clocks so I can have something to post in the Clock Corner--clocks need a little love 😍 I recently finished another Seth Thomas E701 electric clock. Very complex setup, but a fun clock to work on!! It is running like a champ!!! Anyway, the wife complains that it is too loud. I have another one that seems to be softer (not as loud). The hammers have leather tips which are probably original. I wonder if it is worth the effort to replace the leather, or alternatively soak the hammers in something used to soften leather.
