Balance roller pin and passing hollow not aligned (Timex Viscount)

'67 Timex Viscount Automatic

In trying to determine the cause of a lousy 80° amplitude on an ebay purchase, one of the things I noticed (or maybe caused) is that the safety roller and passing hollow rotate freely and don't align with the roller pin. This has made it exceedingly difficult to align with my pallet fork.

As I'm becoming proficient in leaving watches worse off, I'm wondering if there's a way to correct this without replacing the balance wheel (good one shown on right). I don't have the skills to remove the wheel from the hairspring and then replace with the new one, nor the equipment to see what I'm doing.

Short of a mini-drop of super-glue on the back, any suggestions? Thanks! - j

I'm assuming if you grab the safety roller and rotate that it rotates freely? then when it rotates is it rotating on the balance staff or is the entire balance staff rotating?

It appears the safety roller is rotating freely. Not only that, but it appears to be lifting up. Looks like I'm going to need to align it and then tap it down, all with improvised/improper tools. Perhaps this is something I can use the pin-pusher/extractor that came with my watch repair kit, because then I could go slowly (and practice lining things up with my good wheel)...?

And... the lower collar (and hairspring) slipped off, which is good because if it did it made it easier to push the balance staff down to a better depth (using the pin pusher) and then eventually sliding it back on. Didn't look like I messed up the spring and everything seems aligned right. Now I just need to put it back together...

      Etachron regulation system

      By BobG · Posted

      My understanding is that In the Etachron system the spring is only centered n order to set the stud angle when the the pins are wide open and the regulator block in at the midway point.  After that the pins are rotated in one direction only so that the width between the spring and one of the studs is 1/2 width of the spring. This results in the spring always being closer to one stud than other one.

      The idea is that the spring is centred between the pins when at rest. Then when the watch is running it will oscillate equally between the pins i.e. bounce off one pin then the other, as the hairspring breathes. If the spring is only hitting one pin, then it isn't centred, and most likely the pins are too far apart. Yes, the regulator pins are there to adjust the effective length of the hairspring. The spacing of the regulator pins should not affect the amplitude.  The vertical positions typically have lower amplitude than the horizontal ones. This has nothing to with the regulator - hairspring interaction. Increased friction in the verticals sucks energy from the system and reduces the amplitude. If the amplitude is less, the breathing is less. More tim between the pins = more effective length. Depending on how well the hairspring is centred, and which direction it sags, some vertical positions might run faster than the horizontal ones, and others slower. For example, if the spring is off centre towards on pin, and pressed against it by gravity, it might never bounce off that pin => faster. At the position 180 deg. away, the spring will spend more time in between the pins => slower.

      A lathe with indexing that won't break the bank?

      Thank you all for the tips and insights. I'm looking carefully at the Sherline lathes with a milling attachment. I need to figure out exactly what I'd need to get in terms of the base lathe and attachments to be able to fabricate basic parts and learn how to fabricate some of the less basic ones- like a cannon pinion. Thank you again.
