Advice regarding a Zenith Chronomaster Moonphase cal. 410 in gold

[Spacetimetraveller]

Hi, watchpeople!

I have found this Zenith Chronomaster Moonphase ref. 30.0240.410 in yellow gold for sale at a dealer in my town. It comes with box and verification/rate papers, but no certificate. The asking price is 70k NOK, the equivalent of 7700 USD / 6500 EUR at the current exchange rate. There is no mention of service history; only the usual "checked by watchmaker and in very good condition".
What are your opinions on this? Does it look good? Is there a miscoloration or dirt on the wheel in picture #3 that I should be concerned about? What about the coloration on the small screws that hold the caseback in place? Do you see any sign of overpolishing?
Is the price right (most asking prices on Chrono24 are priced higher as usual)?

If I buy this, it would be my first gold watch. Do any of you have gold watches in your daily rotation? Does gold hold up well in everyday life? I don't do mountain climbing or other "hardware-demanding" tasks, and I have three steel chronographs as well.

I have received a couple of more pictures of the back side of the watch. It does seem that there is some sort of miscoloration on the reversing wheel of the winding mechanism seen through the rotor. The clutch wheels do not have this coloration. What do you make of this? Have you seen anything like this before? Does it mean there is dirt floating around in the movement? Apparently it doesn't affect the timekeeping of the watch since I assume "checked by a watchmaker" at least means a watchmaker has tested it on a timegrapher, and also that the chronograh starts, stops and resets properly. Ditto for power reserve.

It’s a beautiful watch model and great movement. Preowned zenith, especially in pm, is crazy value for the money. Don’t just buy it because it’s affordable. Make sure it’s the one you want.

Superb piece. But I wouldn’t pay anywhere near that.
