I was lucky enough to find a 6146-8000 Grand Seiko in great cosmetic shape, glaring one obvious exception - the gold GS medallion is missing on the back (see pic). I'd like to remedy this situation, but my searches haven't gotten me anywhere except that they sometimes appear on Yahoo Japan Auctions, which isn't an option for me as I don't speak Japanese. I would prefer an original, but given that I assume it would cost a small fortune I'd take a well-done aftermarket option. Any tips on where I might locate one?
Also, any idea how best to attach it? I don't want to screw up the back using something inappropriate, but I assume it is attached with a kind of adhesive.
Thanks for any help that can be provided. A photo is attached - when I have the watch in hand I'll upload some real photos, including ones of the original (!) mesh band.
