The CEV number has been erased, but it was officially confirmed by Breguet.
Which is interesting is that it is one of the few CEV with 2 counters.
Credit photos: Menta and Christies ( if my memory serves me well ).

Same watch, but different bezel:

And now, the CEV 1, from the Breguet Museum:
A legend, with only 80 pieces made.
Best,
