This watch is so retro-gasmic it’s amazing. It has an LCD read out along with a clever little crown on the side to set the time. Interestingly, BWC launched this model in 1973, just a few months after the Hamilton Pulsar hit the swingers clubs of the 1970s and, even though the Pulsar used a far inferior LCD technology that told the time when you pressed a button, the BWC was an absolute failure.
This story defined the Swiss watchmaking industry for years until they finally figured out that a certain subset of rich nerd wants mechanical watches of quality. Thus a billion dollar industry was born.
