Extremely rare and unique Jean Marcel watch with ETA 2894, modified to accept an orbiting jump hour module by Vincent Calabrese, independent watchmaker back in the time. It does sit well on the wrist and is a very nice talk piece. This is the first model we see with a gold plated case and find that it matches perfectly the  very complex enamel dial.
