Hi everyone, 

I am putting together a Glycine Airman SST. This is the model with AS movement and a tiny "hacking" spring/pin on the movement ring that I know is supposed to "pop" through the dial when the stem is pulled out, thereby stopping the seconds hand. Does anyone have any tips, tricks, or general direction on attaching this spring/pin through (around?) the stem and through the dial? How far is the spring supposed to stick out the dial when the stem is pulled in? I'm really not sure as to the exact shape it's supposed to look like upon assembly. Any help is appreciated! I have attached a photo of the spring as it looks now.

According to Ranfft    The early versions were based on the Felsa 690 to 698/99

the laters ones had ETA 2789 movements   and AS movements but you say yours has an eta it could be its the 2789.  I have attached the the tech sheet for th ETA movement.

This shows an eta movement, OP says his watch houses an AS calib.

Noted ... I'd taken this to be a general question around this type of Glycine hacking feature, pin sticking out length and so on and was under the impression this was a solution that Glycine retrofitted themselves rather than it being a standard AS, or other manufacturer, hacking feature. I'll look out for further updates with interest!

The movement is AS 1902/1903. I have attached a photo of the movement, one of the stem with the "indent" where the pin is supposed to attach, and one of the dial with the hole at 12 o'clock where the pin should pop out of. 

The gentleman on this link goes into detail about this type of hacking mechanism, but I'm still not sure how the pin should be shaped, ie. how it is supposed to attach to the stem and how much should it protrude out of the dial when hacking is on or off.

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      By VWatchie · Posted

      Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.

      I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.

      Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.

      Broken watch stem in watch crown

      By Poljot · Posted

      If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
