Summary: a large and very difficult "Just Sports" model to find, this is a Justex 47mm "Pilot" with 7750 automatic chronograph movement.
Information on this model can be found here:

I also have the slightly large 51 mm Justex "Pilot", shown here but not yet photographed:

Purchased from the original owner a couple of years ago, both Justex watches have been gently worn but definitely not abused. Excellent+++ condition, both Pilot 47mm and 51mm models originally retailed for $1,950.
