Here is this 1971 Bulova men’s wrist watch. This watch is a midsized to small watch that is light on the wrist. The case measures 28mm wide (not including the crown) and 38mm from lug point to lug point. The watch will fit a 6 1/4″ to about an 7 5/8″ wrist, with the current NOS band.
This watch keeps time. The bezel and back have light wear. I just replaced the crystal with a NOS GS crystal. The vintage calf skin band is New-Old Stock, but does have some chipping on the end where the band rubs between the lugs.
