Perhaps because plastic in 1970 was what carbon fiber and silicon are in 2020?

plastics were considered 'space age' materials back then, didn't have the downmarket stigma of these days. am reminded of the career advice to dustin hoffman's character in "the graduate": plastics. also, i recall seeing magazine ads from the early 70s, for bell bottom pants made of teijin tetoron polyester -- purportedly the height of fashion!
I wonder if itβs similar to the Delrin brake on the Speedmaster cal 1861. They use metal for display back cases. But for closed back, they used plastic.
Looks neat. Like the cushion shape. Charming watch. Tfs. π

Why plastic, perhaps to cut cost and to also experiment. The 70s was the era of the quartz and it threatened traditional watch making. Just my thoughts.
