Phew, I'm jealous, I bought like 20 watches from Japan, none of them came with a box 馃榿
Beautiful box, I don't know whether it's rare, but obviously it's valuable - at least $50 for the box I imagine?
Edit: This one time, one seller said he was the first owner of a watch, a 1968 Constellation, I hoped he'd somehow send it with original box papers, but nope, not only that, but the watch also had issues not advertised 馃榿
