When it comes to chronographs I am clueless so I would like to hear what people think of this. Also what model number is this. Asking $3100 Thanks
At that price point I would want more photos of the case and dial, and at a higher resolution. You want a good hi-res shot of the printing n the dial face if possible. Price seems low for a solid gold case (which looks a bit polished, but more photos needed), but the rectangular pushers tend to sell for less from what I have read because they are more prone to moisture intrusion.
Regarding to your model number question: at the time of the 146 HP movement, Zenith wasn't really consistent in model number designations as far as I know. This would be the gold version of the A273, so G273 if you'd like, although I have never seen that designation being used. (Or the 3 register version of the G171, therefore G173, which I have seen used once on a very similar - but not identical - watch) Perhaps someone with the Rössler book can weigh in?
I don’t know captain W that is a nice dial. You are the Zenith man in my eyes but if it really gets you and you can swing it it definitely is a looker.
