['68OrangeSunshine]

I don't think a watch would stay in that position very long the way I drive and use the sun visors.
In Arizona we have an active and agressive Sun.
I often use the sunvisors against the glare of direct sun at or around Sunrise or Sunset.
Even in winter.
I pull it straight down if heading E/W into the sunlight or flip it 90* paralleling the window, N/S.
Southbound, going Downtown in the morning -- breaking dawn in my eyes -- and Northbound, against the setting Sun in the late afternoon.

A watch on a twist-o-flex type band might get flung off, and possibly fly out the window.
