Hello! I just want to give a head's up to anyone who's opening a jungahns J687 movement - the ratchet wheel screw is left-hand threaded. I found it the hard way - I had to replace the barrel arbour It didn't have the usual 3 line warning. Also I was used to the crown wheel screw being left-threaded.

I have an old Ollech & Wajs Kartago diver, (similar to the M4) from around yr 2000. I am trying to rejuvenate the piece but the bezel clicks are missing from the case. I am not even sure how they worked. All I am left with is the case with 1 small hole located under the bezel ring that is about 1mm diameter and about 1.6mm in depth. I am guessing there was a ball bearing and a small spring that pushed against the underside of the bezel. Does anyone have any familiarity with this particular watch, or in lieu of that, this type of bezel ratchet. I don't dive, so I could just re-install it with a rubber gasket for some friction and leave it at that, but I was hoping to return it to like-new working order. See the attached pictures for the hole and the underside of the bezel. I am learning how to do some of these things, but there is so much brand-specific detail with no resource to ferret out the issue. Can anyone help?
