update for those interested: I did end up making a deal for this, for about 20% less than the original price after discounts, and I'm glad I was local to it, because when I arrived to pick it I got to see the face of the seller when he discovered his watch wouldn't wind. He's going to have it serviced and I'll go take another look at it once he does, supposedly in the next few days (assuming his watchmaker can actually fix it).
This guy appears to have a decent enough reputation and I can't imagine he expected to fob me off with a non-working watch in a face-to-face meeting, especially when I didn't pay cash and can reverse the transaction. On the one hand were I to go through with the transaction the watch would now be freshly serviced while on the other, it's always possible there's something funny going on with the movement.
As far as I could tell looking at it in person, the pushers appear to be identical, but I must agree that in the photos they don't look that way. Whether this is a matter of the perspective I'm unsure.
