My contribution to the sometime Oppo Watch Show is my 1968 vintage Bulova Accutron Spaceview, which my grandfather left me when he passed away about 10 years ago. It still keeps time (or it does when the battery isn't dead) and gives off its pleasing tuning fork hum. It needs a correct crystal, band and a good cleaning to be 100%. Until then it sits in its original box in my dresser.
