Here is a large and chunky 36.5mm. stainless steel vintage 1960’s reference 43999 Grand Seiko “self dater “with an original dial that has taken on a wonderful patina. I really like the sharp and polished famous beveled Grand Seiko steel hands. The fine and excellently finished caliber 430 Grand Seiko movement was just cleaned and is accurate with the quick-set date feature. This watch has a generic unsigned winding crown. This vintage watch has NOT been polished and retains its beveled edges. These watches are currently undervalued in my opinion. The dust particle above the K in “Seiko” in not present, as it was on the crystal.
