Here's one you don't see very often: a 1969 Bulova Accutron Astronaut Mark II with the red date at the 3 and the red seconds hand.
And in minty condition. Keeping excellent time, all functions working as they should.
Classic dimensions: 35mm wide by 41 mm from lug to lug.
Accutron fans -- and we're counting ourselves here -- this is a "grail" watch.
