I know that watch, I had on my hands 2 times when It was in action in Vercelli MertingArt in Italy. The First time was unsold (15k eur hammer) and I missed in NOS conditions.
The second time was not NOS anymore, and not full working and they sole for a very higher price on auction.
The item is 1996, probably unique piece because of early production but also because in palladium, Number of caliber is 13 (or 17?). The most focusing detail of "pre series" production are the stright lugs, and missing a proper strap and buckle, as it had made for expo only or for a show, and not to be wristed.
Congrats you have actually!
