1675/16750 - Three new contenders

[fizz]

So I made a previous thread here about another 1675 where I got great feedback but the price is high (still negotiation on that). In the meanwhile, I managed to source the following three as well (I have posted the same images in the previous post but putting it up here again to get better responses).

Which of these is worth pursuing and (perhaps) eventually picking up?

I've given the main details that I have but some of it is still coming in.

Here are some other contenders thrown into the mix. A bit about each:

Pic 1 - From 1984 (model 16750). Service date wheel (white) so no open 6 or 9. Asking 9k USD. Is the bezel correct? Seller says it is. I'm turned off by the date wheel colour but otherwise like it.



Pic 2 - From vintageconcept. Asking 9.3k but assuming this is list price and can be negotiated. From 1972. Know very little else about this but have asked questions. Date wheel looks ok. Insert I don't know.



Pic 3 - Also from 1972. Much lower price (8.5k). Can't tell properly but looks like replacement hands? Also, the bottom right lug looks unusually thin (or is it just me?). As usual, no idea about insert but seems replacement. Can't tell about date wheel but looks silver but have asked. Very reputed seller.



So which ones would you prefer?
