In 1971 Mr. Alstater retired and Star Watch Company of Los Angeles continued releasing watches under the Alsta name until 1978.
In the struggle against the quartz watches dominating the lower end of the market, Alsta began using a new 70s-vibe logo, and began to market the more famous Nautoscaph and Superautomatic. The original ranges were powered by a Felsa 4007N movement, and later an ETA 2452 or 2783. The rarest combination, which appeared on both model ranges, was the A. Schild 2066 movement with a day-date complication.
Alsta unfortunately succumbed to the ‘quartz crisis’ (the advancement in the watchmaking industry caused by the advent of quartz watches in the 1970s and early 1980s, that largely replaced mechanical watches around the world) in 1978, and had to shut its doors. It was surprising that Alsta did not venture into quartz watches, as throughout its history it twisted and turned, was at the forefront of trends, made white label watches sold by other brands, and usually found success at whatever it did. Arguably, Alsta could have made a success of a range of quartz watches, but we shall never know. They officially closed in 1982 although the final watches were produced in 1978.
