FS is my King Seiko 45KS 4502-7001 from 1973. Excellent vintage condition, all original and unpolished. As such, there are some scratches on the case and light scratches on the crystal, which I don't notice while wearing. Excellent, honest example with sharp edges. Dial is perfect, which is rare. Gold medallion on caseback is in great shape, and the previous owner put a plastic sticker on the caseback to preserve it. I haven't removed the sticker. Quickset date works perfectly and flips over at midnight. It received a recent, full service from a watchmaker in Japan who specializes in vintage Seiko. I don't have the paperwork, but will include pics of the disassembled movement. The movement is the legendary hand-winding 4502 hi-beat, which beats at 36,000 bph and is one of the last movements Seiko assembled by hand, before they went automated. It loses a couple seconds a day for me. The case is the 45KS, and it's what Grand Seiko refers to as the 44GS today. Case is 36.5 x 42 x 9 and wears wonderfully. I'll post a pic on my 6.75" wrist for reference. Comes on a new Tuns strap with an aftermarket KS buckle. I can include a green gator pattern strap from Moratello for a dressier look. Asking $750 shipped in the US. Thanks for looking.
