Corum Bubble Joker

I thought I’d feature this as it’s a watch you don’t see very often, Corums Bubble Joker ref 82.240.20 which was created for their collector series. This particular one is powered by an ETA 2892-2 with a chronograph module on top, I believe some were powered by the Valjoux 7750 movement. Corum produced 777 examples of this particular model. The chronograph hand had become detached on this one and it needed refitting and of course investigating as to why it had actually come off.
