CASE: 39mm without crown, all steel; these panda Wakmann triple dates came in 2 sizes (37mm and 39mm), and came either plated or all steel. By far the least common configuration are models like this—39mm, all steel. It has it's original signed crown, and the inset pushers at 8 and 10 control day/date and month functions. The acrylic crystal was just replaced when it was serviced (by a CW21 watchmaker here in Indiana; the watch has a 1 year warranty). The case doesn't seem polished, and there are signs of wear, but nothing (imo) egregious.

DIAL+HANDS: untouched/original and no flaws that I can see. Pictures are the best description, but this is as good an example of a jumbo as I've seen in a while.

MVMT: the Wakmann-signed Valjoux 730 was just overhauled by the best watchmaker I know, and, again, has a year warranty. Everything works exactly as it's supposed to: chronograph starts/stops/resets exactly, pushers advance triple-date markers, etc. This watch should work just fine for quite awhile.

Price is $2700 net to me; watch and I are in Indiana/USA. I'm happy to answer any questions or provide as many references as requested. Thanks for looking, and huge thanks to everyone here for the great resource+community.
