Corum Anniversary Automaton Quarter Repeater made in 40 examples, 10 in white gold, 10 in yellow and 20 in red gold. Made to celebrate one of the anniversary of the company completely assemble Christopher Claret. I tried finding more information not much ...
This is such a rare timepiece...made by a genius...as far as I remember the base of the movement is a Frederic Piguet 71...would be interesting to see the quarter-repeater module commissioned to Claret...
