IWC FLIEGERUHR CHRONOGRAPH IW377701

Hi, I need another pair of eyes to check if everything is legit on my Watch
-thank you in
advance

Why do you suspect your watch?

I got it in part exchange from reseller I'm not familiar with and considering
the current situation could not check with official service
center/retailer...So just to be on the safe side.

Are we even allowed to offer opinion? Then, what is an opinion worth when it
is based on three photos of a watch?

As I study the photos, it appears to me to be a legitimate IWC Pilot 3777. But
take that for what it is worth, not as a guarantee.
