Thank you,

but, after seeing your watch building threads, i think you are the last person to fall off a chair seeing my amateur trials. I've seen what you can do, your work is amazing.

I am not a watchmaker, let alone a professional one. I have been making knives for the past eleven years and made a watch from time to time in the past four years or so. Those watches, however, were just a simple assembly job - i made the case, dial and hands and put in someone's movement. Sometimes i cut it up a bit or added a couple of wheels (power reserve etc) but really, nothing complicated. I don't do that anymore, because i want to divert all my available time to this - making entire movements, all the parts. We'll see how that goes

The perpetual calendar was a lot of fun, this is actually a fourth version i think, a first properly working one ( i do a lot of trial and error ). Sometime in the future when i get the tourbillon movement right, i would love to add this QP mechanism to it. That should be a lot of fun as well

The clamp for the hairspring is really easy to use ( from a assembly standpoint, and it minimizes hairspring manipulation for me ) and after measuring the exact radius of the outer coil of the hairspring ( on a optical comparator like digital machine ), i was able to machine it so the hairspring is perfectly centered. Also, because i made a bit of a mistake ( read huge mistake, almost fubar ) on the balance wheel, making the parts where the screws are too little in diameter, there was no space for the hairspring holder at the hairspring level. At least not a robust, nice one (there would have to be a very thin, flimsy one).
So i did dare and bent the dogleg of the spring upwards, like if i was doing a overcoil... I thought it would mess up the whole geometry and everything,but when i tightened the spring in the holder, everything remained centered, the hairspring is flat and is breathing nicely in all positions. Which is surprising, as i didn't even bother poising the balance yet. I was curious if it would even work, fine tuning is what comes now.
I'll let you know how it all turns out,keep you posted

Take care,
Ondrej
