Hebdomas repair standards

I am working on a Hebdomas for my mom. She wants a butterfly painted and I figure I can put it on the inside of the watchcase back. The question I have is the ethos of updating the watch. Right now, I am fitting hands and thinking about the minute hand. The cannon pinion is basically a tube with a gear attached that sits down in a recess. As you can imagine, its difficult for me to 1. .Remove the pinion because there's nothing to grab onto 2, adjust the pinion to the wacky pin they have running through the second wheel so it slips accurately (a first for me personally) and 3. size the minute hand to fit onto the pinion so it slides down to stay tight and true parallel to the hour hand/dial face.

That pin has to be tighter in the second wheel than it is in the pinion and I think I have that covered. The thing I did was to turn a recess in the middle of the pinion and then true up the end and turn a slightly smaller diameter on the end of the pinion to the depth of the thickness of the minute hand. This will give me a place to grab for removing the pinion and a shelf to help the parallelism of the minute hand and also a stopping point before it hits the hour hand.

Is this an "ethical" repair? I've updated the watch to newer standards.  As I've gained more experience, I've seen how many hacks there have been through the decades and I dont want to be one of them.

What is the current popular opinion on this?

A hedonist would say go for it if you want to. The divinely commanded would shrug. Utilitarian... probably shrug, maybe feel slightly against? Deontologist would probably shrug, maybe lean slightly no but slightly yes... That's all the schools of ethical thought I can come up with before I've finished my first cup of coffee. Point is, ethics doesn't really apply...

Contemporary norms, on the other hand, would probably suggest you don't, but personally as long as it's well executed, it's her watch and it becomes part of the history of it. I wouldn't do it personally, only because I'm not a good painter; but I wouldn't hesitate to find a good painter and have them do it. Maybe go one up, and see if you can find a cloisonné artist, and really do it right in a way that will last.

thank you for your well thought out reply. 

I am a painter so thats not an issue, just the thoughts about changing it from the original manufacturers intentions. It's also been a pain to remove the pinion without anything to grab onto

Unless it's a Harrison Chronometer do what you like, it's your watch.

If you're going to paint a butterfly on it, do not forget to place your signature somewhere near.  Imagine if Vincent van Gogh owned a watch and delicately painted the inside cover.  If you're going to do it, do it well, and sign it.  Just my 2 cents.

      Regarding the spring winders, I made my own and used copper pipe reducers as the tubes to retain the spring. You will need to cut out a section for the end of the spring to protrude but if you watch one of the many videos on this subject that will make sense. You can find a selection of sizes on Ebay for very little cost. I'll attach a pic showing one of mine.  Good luck!

      Omega sweep second pinion friction spring - correct tension IS important

      By JohnR725 · Posted

      There were things bothering me about this discussion that took me a while to figure out the problem. In the image below it appears to be the spring may be pushing up? Normally when Omega has a spring pushing up the pinion has a pivot with a bridge to hold it in place so in other words the spring can push on something that stationary as opposed to this which appears to be floating? To understand the problem with the above image we need another image of side view which I have below. In my image down below on the left-hand side it agrees with the image up above. But the only problem is the left-hand side is defective and the right-hand side image is the way it's supposed to look. Then Omega if you can access the right documents does explain how and why this problem occurs. With the pinion floating around it might be assumed that you support it when putting on all the hands but you do not because as noted below if you do this small bush on the pinion will relocate out of position exactly what we see in the image up above.   Then Omega does not mention this but there is a possibility of also damaging the pinion and causing the bush to move to where it's not supposed to be when removing the hands.

      Regulating is too touchy

      Maybe show us 1) the watch, 2) timegrapher readings in DU, DD, PU, and PD.

      The timegrapher displays significant beat error variations in the dial-up position. When the watch is lying flat (face up), the beat error is much higher than in other positions. Beat error readings are inconsistent, with especially large gaps in the face-up position.  Please help !

      Looks like an open-access journal that runs as a glorified pre-print server with no true peer review, so it’s not easy to judge the veracity of the conclusions.
