This is a Bulova waterproof calendar watch.  Unfortunately, this watch is no longer considered as a waterproof watch.  In fact, the term "waterproof" is discontinued since the 1970s.  The term "water resistance" to a certain depth replaces the term "waterproof". It is an outstanding piece that is sharp and attractive. Watch is original and has been serviced prior to listing it on the site. It is working strong and accurate. The stunning dial is factory original and in very good condition. Brand new crystal and brand new genuine leather strap.
