This is a rare find. I have come across a few of these from various makers over the years, but they are few and far between. I think that this was likely a store display to show customers how the Incabloc shock protection worked on Ernest Borel watches. It could also possibly be a teaching aid for watchmakers.
This was made in Switzerland for Ernest Borel and Jules Borel of Kansas City. This measures about 3 1/2 inches long. Please see my other listings... Please note that all pictures are taken on the macro setting.
