I'm totally new to vintage watches, and I've been following a number of eBay auctions for late 60's constellations. I thought I had got a pretty good idea of prices. But then two stainless steel w/ white gold bezel (one cal 751 and the other 564) sold for ~£300 ($430). This seems absurdly cheap to me, but to my eye nothing seems wrong with the watches.
So to your trained eyes, can you tell me what (if anything) made these two watches sell for so cheap?
(NB: I didn't actually buy them, I'm just interested for future reference).
Watch One:

Watch Two:

Cheers for the help.
