Looks pretty good. At a guess I would say it's the quartz version. If the seconds are on the 6 dial, theyre in the wrong place. The 'b' on the end of the large seconds hand is usually a dead give away, but it seems to be shaped very nicely on this one. Sub dials are too close together, and the date window is too small.
The overall impressions are very good though, especially the date wheel positioning, and if that is a quartz, the knurls on the bezel are pretty good too, I have seen some very bad ones, they are usually too thick. As in the gap from the inside of the gold coloured part to the outside is too wide (if this makes sense) This is the same on the 7750 version available too, if you see a gen Navitimer, this 'ring' is very thin, but this is by far the best version if it is quartz!!
Great purchase!
