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.


You can see the stray hand in this shot. The dial has the jokers face and the four suits of playing cards arranged around the subdials.


I was surprised to see two springbars in each end of the strap, you’d have to be unlucky to suffer springbar failure on this!


With the caseback removed you can see the 2892-2 movement with its decorated rotor.


The loose hand was examined and pronounced fit for further duty. I was expecting to see that the hands pipe had split as it was rattling around in the case but I think it just hadn’t been fully pressed home at the last service and eventually came off during a reset.


The hand was successfully refitted.


What an impressive crystal, it’s not hard to see where it got its bubble name from.


The movement was refitted and everything was nipped up tight, all done now.


Back on it’s impressive deployant strap. What a wacky watch the Bubble Joker is,  I love it!
