Anybody familiar with this type of cap jewel? This is from the platform escapement in my Chelsea model 12 E Ships Clock. The serial number on the clock dates it as a 1970s manufacture clock. The platform has an Incabloc logo on it. I would like to know how to dismantle it to clean it properly. I originally just cleaned it in situ and oiled it through the triangular opening in the cap jewel. I originally posted this in the clock repair forum but thought I might get some replies from the watch repair experts as they work with lever escapements routinely. Thanks for any help!!!
