Nop, the eccentric You need is where the red arrow points. Hopefully it will move. -

Hello and welcome from Leeds, England. -
I'm fixing up another Landeron 48 - this will be my 4th one of these so I'm getting the hang of these a bit. I got it as a non-runner (pallet fork pivot broken, barrel tooth broken) and replaced those so that it runs ok.  Reassembling the chronograph I've hit a snag. The watch stops when the chrono is engaged. I think the teeth are too deep. I think the eccentric to adjust that is on the hammer, circled in the picture. It won't move. Any suggestions? -
Success, and failure. Balance is back together. I need to adjust the position though as the roller jewel is way of. More than that though, rookie mistake. I set the hair spring between the pins, forgetting that to rotating pin is oval. So when I close it up the hair spring is in contact with the outer regulator pin. I assume that's bad. At rest, without the outer pin rotated closed, it sits like this. Edit... I've been reading and I now understand how the gap should be between the spring and the pins. I'll have another attempt at this. Oh, and the pivots look like this. It's not a banana, it's just because of multiple lenses and trying to get a high mag photo Slightly wonky jewel  But, the free oscillation test, 180 degrees, USSR makes that 53 seconds   -
Welcome the the forum. Are you talking about the part of the stem that fits to the crown? Photos would help. Â Â
