1680 bezel tension

[WeylandYutani]

So I just received my JK 1680 and I'm am curious as to how easy should it be to move the bezel, not take the bezel off but just move it back and forth. Mine is very easy to move. It seems too loose. But i don't know how they are supposed to feel. Also if it's too loose how do you go about tightening it specifically. The watch is awesome. Smaller than I expected but very cool. Thank for you input. ????

The looseness of these varies. Under the bezel there's a metal shim - a flat metal band that is supposed to act as the tensioner or friction plate for the bezel movement. If you pop the bezel off (which should be dead easy - often just by using finger pressure, otherwise with a case knife) you'll find it underneath. If you put a bend or two in the shim (actually crease it), then re-fit everything together, you should find the bezel is a little more stiff to rotate.

I’ve also read of people wrapping dental floss between the case and bezel to stiffen the movement up. Obvs the method that p0pperini mentions above is a much more refined way of doing this. In terms of tightness, mine was loose when it arrived. Since tripdog breathed his magic on it (i assume he used a similar technique to the bends mentioned by p0pperini) I can use it as a functional bezel without worry of it slipping or being knocked.

I'm more familiar with hearing about this technique being used on 5 and 6 digit Rolex bezels. I had a 5 digit once that this had been done to. I've not encountered it on a 4 digit - but it may still happen!

Ah...I’m probably wrong then...I assumed it would work with any non ratchet bezel, but that’s probably inaccurate. I think your method is superior regardless, so the OP should probably attempt to remove the bezel and bend the shim.

There's a friction washer that sits between the retaining ring and the outer bezel. Roughly, the more you bend it before installing the outer ring, the stiffer the bezel will turn.

Awesome thank for the responses. So I have taken the bezel off and it was super easy. I know what ring your talking about and I tried adding more of a radius bend on it using the ball of a truck hitch. But without a hammer it didn't work very well. So basically your saying make the ring wavy while still maintaining the slight curve to fit the tenai

Got the tension ring that holds the crystal in

This is what shape i jt did with the rounded end of a butter knife. And the tension is awesome now. Thanks guys

Just bend it in half with your fingers, just don't go all the way

So the reason I went with wavy, have you ever taken apart a bearing assembly out of an electric motor. Well the friction washer they use are wavy. Once you mentioned bending it, It just popped in my head, oh yeah do it like this. Worked really well

 

[WeylandYutani]

Tension spring for a bearing

Tension spring for a bearing

Well that should work as well

Now I need to take mine apart and bend it more. I only did it in half and its slill loose.

Make 3 equidistant sharp(ish) peaks in it .

 

[muiramas]

Thanks bro. Will do.

I stacked two, one brass one, and one stainless one that I bent in the same manner as you. The brass one is nice and grippy. On the gen it should be fairly hard to move until you push down on the bezel, then it will compress the wavy shim and turn more freely. The two stacked shims accomplished this very well on my watch. Every few years I pop off the bezel and re-bend the stainless shim. It tends to relax over time

I always put a layer of packing take on the tension ring. The cartel tension rings are too thin and lose imo. Once I thicken it a little bit, I do what everyone else mentioned. Bent it on 4 sides. Then you should need to push down on the bezel to turn. That’s how the gen version works.

It works for me every time.
