I *STILL* have it, and wear it often, as John Ackermann can attest. Heh, me too. I got mine in about 1970, the "astronaut see-thru dial", of course. Wore it until about '79 when I got the very first "Sensor" LCD digital watch that JS&A wholesale sold for about $200, complete with the tritium backlight. Remember JS&A? I took the Bulova to a jeweler a few years ago for a tuneup and a new crystal and haven't seen it since. Jeweler claims it "got lost" but I think it found a new home.... I was an apprentice I&C engineer working for TVA back then. A bunch of us in the instrument shop got those Sensor watches at the same time and, guys being guys, quickly got into a timekeeping contest. Initially competition involved trimming the oscillator capacitor inside the watch but that quickly escalated to making tiny chip capacitors, looking for the correct TEMPCO. We had a large environmental chamber that made dozens of runs, sometimes with dozens of watches inside :-) I got mine to about a second a month but there were guys who did better. Mine was actually better than that under normal use conditions but the rules of our contest specified the watch be removed from the wrist every night. This was to force everyone to deal with temperature compensation. I still have that watch. It still runs but the tritium has been through enough half-lives that the glow is just barely discernable to night-adjusted eyes. When new, it glowed brightly enough to use as a flashlight for finding keyholes and the like.
