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.

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.

      Tweezer hack.

      By Neverenoughwatches · Posted

      If you tend to be a little heavy handed then heres something that might help you to prevent cap jewel loses if you have some spare tweezers. File a round into each of the tips so you can grip a capstone or chaton while oiling or moving them around. Instead of filing along the length, angle file the tips first then file the rounds perpendicular to the angle. This way the tweezers wont get in the way of the oiler. Choose an angle that suits your natural hand grip position. The tweezers can now grip round parts on four sides Instead of two that often flip that part away.

      Seiko 6601 Tech Sheet?

      I had noticed that video before.  He has a separate video for the reassembly. When he started the reassembly with using peg wood to oil a jewel I have to admit that I didn't watch much further. He also advocated not lubricating the center wheel arbor because the cannon pinion is friction fit. There is also a blog post (Adventures in Watchmaking, I think) that has a bit of info but not much at all with the oiling.

      What is the correct way to lubricate clock mainsprings?

      By HectorLooi · Posted

      In view of the modern lubricants available, would you lubricate a clock movement differently today?

      Yep thats the way it goes. The trick is to lead it into a false sense of security. Go through all the motions of ordering another one but dont actually click that final buy it now button, then stand up say " oh well at least I have another one on the way" .  It will pop its head out and shout " SUCKER ! " . They've done studies you know 60% of the time it works everytime.
