Could this be a prototype of a well-known wrist watch ?

 

I don't recognize anything..but if it's a quartz watch I'm not very interested..

 

Here's another ESA-photo showing the watch... which displays PET - Phased Elapsed Time to the countdown & moment of launch ISS40

.

 

I am almost certain that it’s a Halda Space Discovery

FYI:
HALDA "space module" used by Swedish ESA-naut Christer Fuglesang flew 13 days aboard shuttle Discovery to ISS (2009) and 165 days on ISS-40/41 worn by German ESA-naut Alexander Gerst (2014)
