Tomorrow should be "The Day" for Felix Baumgartner's daring jump (Home | Red Bull Stratos). Even though I am myself a Zenith fan/owner, it is not the first brand I would think of for this kind of activity. Instead of Zenith Stratos I would rather consider some instrument type watch, more legibility/ruggedness and less luxury feel/looks. Probably something Lemania 5100 powered from Omega, Fortis, Sinn or Tutima. Valjoux 7750 based IWC 3717/Damasko DC66 or Speedy Pro/Bremont come to mind also.
Of course it is all about sponsoring, Felix's trick won't be cheap and Zenith obviously has better recourses to help financially than smaller brands. But if we cast money and availability aside, what would you pick and why?
I hope everything goes tomorrow as planned and Felix returns down to earth safely.
