Hi,
For me if its a hot crowded weather i might be putting up a GP BMW-Oracles in rubber strap or panerai Regatta in rubber strap.
If its a cooling day ,you would say i will be in my JLC ECW leather strap or IWC Top Gun Ceramic with leather strap.
In my mind,since the event more or less dealing with sport,timing and speed i would say chronograph watch will be the best to fit the enviroment and praticiality.
make sense?
thanks.
