That's beautiful Perry with a simple but elegant dial!
My 5501 from 1970 below; fluted gold bezel and two-tone oval link jubilee bracelet.
This one is a 1965 5500 with alpha hands and dagger indices that does not have the "Precision" script on the dial which was not an unusual combination for the early to mid-60's.
It has the 7835 folded link Oyster bracelet.
Cheers,
Rick
