The static shots are done usually at the pre- or post-event dinner.
You can see the glass display cases and background posters.
I looked closely at the watches on the wrist in photo 1 and it just looks like a normal way to wear a NATO-style strap; what's the problem?
The loose end always flops like that from the steel retainer ring.
From my personal observations at various races that Chopard sponsors, the drivers really are given watches and all of them wear them before and after the races.
Some even wear them during the race!
All competitors at Mille Miglia got a free watch even if their racing team is not sponsored by Chopard.
Yes, it is marketing but it is real and not just loan watches only for the photoshoot.
Chopard gets a lot of feedback from the drivers and reliability data.
I cannot comment on the photo from the desert as I was not there. As it is in one of the most remote and hostile environments in the world, I'm not sure which photographer would stand in the desert waiting for these cars to whizz by.
