Bulova 1960 21st Century

Watch came to me from a non-watch savy source in the box pictured. Box is obviously not correct (Waterproof), but may be the box it came in from the jeweler. It's as clean as the watch and of the proper time period give or take a couple years, I believe. Movement and case both dated M0. Movement is a 10BZ 21 jewels

bourg01 and Lisa both call this a 21st Century based on crystal dimensions. Here is what I believe to be an unmolested sock drawer watch that is basically pristine inside and out with what appears to me to be the original crystal, face,  hands , signed srown and likely the original Speidel band. What do you think?
