路That Timex looks tiny. If you want legibility, you can't beat the IWC 55mm B-Uhr from WW2 馃槂. I hear pilots strapped these to their thighs too.
Ref the thigh strap I have still not tracked down a photo from WW1 or WW2 of a pilot or navigator using that configuration.
I am sure it did happen, just off there are no photos,
