Great watch, too expensive. One of this 3647 N just sold on ebay for 6300 USD but with wrong pusher.

I believe this is all original, unsigned crown is OK for low SN. Like 55xxx to 83xxx. But early case should not have model number(3647) on it. See if you can get the price down and get more case pic.

Good luck!
