What Watch would Indiana Jones Wear?

Now to be clear - we know what watch Harrison Ford would wear - and I respect his partnership as it has a charitable benefit. 

BUT -

What watch would Henry Jones Jr. wear?

I think it would be this one!  I can see Indiana checking the time before boarding his flight to Nepal.  Double breasted suit, fedora and an adventure awaiting.

But then again I can also see him checking the time to calculate what time the sun will hit the map room.

And finally I see him pushing up the sleeve of his tweed jacket to see if the bell is ready to ring and end his Archeology 101 lecture.
