Boy these things **BLEEP** me off.  I love incabloc...everything else sucks.

How do I get this spring mounted.  I have spent an hour so far...no success.

I found this from 2017.  I guess you just shove it in and the fingers will expand and slip in...right!

Hi lws. Looking at this and yours . The short legs clip into the back and the long legs spring out to lock in last yes ? The long legs dont look like they have enough spring in them to lock into place. Was this in place when you got the watch ?

Could we see a macro side shot of the setting.

Yes, the short legs in back and long legs in front...this I know along with the order of assembly.  The issue is getting the short legs to slip under the trapezoidal member which, incidentally, is undercut (not obvious from the bird's eye view.

It is just incredibly fidgety, but I finally got it by using tweezers in one hand and sharpened pegwood in the other.  Once in place, it is not stable (like an incabloc is), so I just slipped the jewel in carefully and locked the long legs.

I am still interested to hear any clever method for dealing with these.

So does the back legs slide in and then lift upwards to attach ? i cant imagine that they spring outward being this short. Do we have a name for this design ? I understand  your frustration lol, i had a tiny diashock type spring with 3 prongs and 3 cut outs in the setting. All 3 had to go in at once and then turn. Problem being only having one pair of  hands 🤦‍♂️. I lost it twice in the end I had to make a pusher out of a toothpick. It was a wonderful memorable evening 😒 .

Choose watches that dont have them 🙂

OK, this one is done.  For the upper jewel, I was UBER careful not to unhinge the spring.

Note...in the picture, the hairspring upper left is not part of this watch.

I was happily surprised to see my Dad's mark on this watch.  He worked on it four times between 1966 and 1978.

👍 Good job @LittleWatchShop. 

I just hate KIF springs. Whether it's Elastor, Trior, Duofix....

I just lost a tiny Trior spring last week. I placed it in a tray while I cleaned the jewels and then oiled them. When I wanted to replace the spring, it just wasn't there anymore! 😢

Luckily I found a spare from a scrap movement.

Incabloc shock springs can fly off too… except that when incabloc shock springs fly off, you may have to remove the entire shock block to replace the shock spring!

I’m not sure if placing a small piece of rodico at the hinged part of the KIF shock spring will help to prevent it from detaching (like with Incabloc), but I would try that. I’ve not worked on any movements with such “captive“-style KIF shock springs.

I prefer to put detachable shock springs into tiny plastic ziplock bags for safekeeping. They don’t really need cleaning anyway.

@LittleWatchShopI just had a similar issue, I was removing the cap jewel and the long arm snapped even before it slid out of its slot. I have found another movement on eBay that has these springs as I couldn't find the part by itself. but a little anxious that I have to first remove the spring from the old watch and then install onto the watch I am working on. Any tips and tricks greatly appreciated!

Cousins seem to stock most of the KIF springs https://www.cousinsuk.com/product/kif-shock-springs

I like to lay a thin sheet of plastic film over the spring and work through it. To get the spring off I would put a large oiler at the back of the spring and just twist it, I bet that would pop it off. Here is how I attached a loose spring on a Bulova. Once i changed the angle of the oiler so that it was pushing along the long axis of the oiler it snapped right in. The plastic film also helps to maneuver the spring into place.

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
