Reply To: jewel clamp on newer wristwatches

Hi C_Kelly,
That would be an Incabloc shock absorber which is one of many such setups. Incabloc is probably the most popular with KIF coming in second.
There is a trick to it. If you look closely you’ll see a groove or channel around the inside of the setting just above the cap jewel. This groove needs to be clear of the plate so that you can insert the “T” end into it’s recess. A jeweling tool like a Seitz is the best thing to use for pressing the setting out and back in but a staking set will work almost as well. The setting usually gives little resistance so it’s a fairly easy job. Just sounds hard here.

Hope this helps!
Please let us know how it goes.
