I've been searching for a few months for a setting lever spring for what I believe is a Phénix 160 (not listed on ranfft) movement without much luck. I find the occasional parts for the movement, but not what I'm looking for. I've come across one complete watch since January, and while it was relatively cheap at 95 euro (final sale on auction, so could have ended up being more if I threw my hat in), I feel the need to exhaust all venues before I decide to buy a donor watch. While I'm aware of the no-go policy in terms of advertising sales on this page, I'm hoping it's ok for me to do hail Mary trying to acquire this elusive part. So if anyone by chance has something like this laying about, or know someone who does, or someplace I can look, it would be greatly appreciated. I've looked through most, if not all of the listed vendors on this page, and I've been popping onto e-bay every other day. 

If I am overstepping my bounds, let me know and I'll delete the post. 

Thanks in advance, and I'll add a photo so you can see both the broken spring, and the beautiful dial.

    • 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.
    • 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.
