    • Hello - I have Tag Heuer F1 Chronograph ca1212-ro, which I've had for many, many years.  Recently I noticed a pusher "cap" had come off and was lost, I have sourced an new pusher, and have removed the movement but am at a loss for how to remove the pusher from the case???  The new pusher is not threaded so I'm assuming the old one is not either - assuming the pusher I was sold is correct.  Are the pushers a o-ring press fit, are they "glued" in, how are they removed and reinstalled?  Any help is greatly appreciated!  Thanks - Nick
    • It would just be a video of me poking and prodding for hours I'm afraid. But the basic procedure for me is, move the index right next to the stud holder, and rotate stud so that the hairspring at this point is centered in the index. Then I move the index little by little away from the stud. If at any point as I'm advancing the index I see the hairspring start to deviate from the center of the pins I back the index up and either tighten or widen the curve, checking the curvature by moving the index over the problem spot after every manipulation. I keep doing this until I get to the dog leg and now I have a perfectly formed end curve. Next is to just fiddle with the two bends at the dog leg to get the collet to center on the jewel. Also check constantly that the collet isn't sticking to the cock by tapping on the cock whenever you are checking your work to make sure the hairspring is in its fully relaxed state. I don't have any special techniques really. It's basically just time and patience. Feel free to ask though if you want me to be a little more specific about anything.
    • Now that this project has been completed, I hope that some of you might be inspired to pick up a scroll saw and try out this craft. Its not hard, just tedious and repetitive but you can make some beautiful pieces of art and there are all kinds of patterns out there for everything one could imagine. This clock is not difficult at all, there are clocks that take guys months or even years to make. Cherry tree toys has the most awesome patterns I've come across and Berry basket has some simple yet beautiful stuff, in fact this clock is from a pattern by Cherry tree toys. https://cherrytreetoys.com/scroll-saw-patterns/ https://www.berrybasket.com/
    • I second this approach.  I'll just add heat can also be used to break down the superglue.
    • I find Seiko HS manipulation to be very difficult. When you have a chance, why not posting a video to show your technique to others.
