Honestly, I got this in a parts lot from a watchmaker and I can't find much out about it. I've seen art deco watches with date function before but I can't recall the wittnauer 9RW being a date function movement.
Missing hour hand and I can't get the date to turn over. It does run though.
Priced as an oddity piece. Might be a deal. Might be overpriced. Let me know.
