FS is a Seiko 6138-0030 Kakume that’s a catch and release for me. I got it very reasonably and thought it might have aftermarket bits, and sure enough it does. The bezel and dial are aftermarket. It seems to function flawlessly (seller provided a receipt for recent service), and is a nice watch, but not the one for me given it’s non-original. Selling for what I paid plus shipping and it’s definitely worth that. Polished case, AM bezel, dial and bracelet.

Price is $450 shipped CONUS for this piece. This is a no-haggle fair price, but that is the price because non-working examples run this much.
