Should I buy a Zenith Chronomaster Sport '21?

[Bensrolex]

I admire this watch but it would be my first Zenith, and I am less familiar with the reasonable pre-owned market and how a pre-owned model may hold its (discounted from retail) value. I have an opportunity to buy a very nice, authenticated white-dial example with original box/warranty card/etc for $7150. This seems like a pretty compelling price for a watch of this quality. Anybody have any pros or cons I should consider? I am aware of the "Zaytona" controversy but it doesn't bother me :) Thanks!
