What I can see looks pretty good, but the same picture at 1024 pixel width would be much more useful.
Contact Ziggyzumba for an overhaul. He can correct the hand positions & fit a gen T21 crystal. As mentioned previously, if the bezel is still loose with the gen crystal, you will need to replace the bezel. A folded link 7835 weighs less (as will your wallet after you buy 1 @ $250-$800), but will make the watch look alot better. I would also consider replacing the aftermarket 'Triplock' crown with a gen crown & tube (around $100+ for the pair on ebay).
Those prices sound rather low for a V72 (very complicated movement), which can take a number of hours to overhaul. Again, try Ziggyzumba.
The screw function locks the pusher so it cannot be used. Unscrew to press the pusher, screw back down (snug, not tight) when not in use.
