I live in Thailand and rarely see any vintage Seiko watches for sale. I mostly collect Seiko Divers (6105, 6306, 6309, Tunas) and buy most of my Vintage Seiko's in the US. I have no experience and very little interest in the older Seiko models simply because they are always very small and I'm used to big, chunky divers. This watch is coming up for auction at my local auction house where everything goes cheap. From the blurry auction catalog photo it looks like a vintage Seiko with applied S logo. It's hard to read the script but might be Extra Flat. Might be worth a lowball bid?
