Computron "LCD" (L on advert)
Wow, we don't see many of these watches, I like it.
1977 Bulova Computron. I'm not 100% sure it matches to the advert as I think this might be a ladies watch and the ad is showing a man's watch.
I did not find a match in our ads, but it looks to be a ladies Computron or LCD. It likely had a model number, but I think we categorize these as Computron (LCD or LED).
