Great piece of work, Ed. Well done.
The only additions I would make are related to radio station WWV, which made time available by shortwave to small boat sailors across the 7 seas.
In 1953, Sony bought a license for $25,000 from AT&T to manufacture transistors.
By 1958, Sony went from being a company with 7 employees to one with 500...and had begun selling what eventually became millions of transistor radios.
In 1966, radio station WWV began broadcasting shortwave time signals around the world from Fort Collins, Colorado.
I think the combination of transistor shortwave radios, station WWV, and Seiko's quartz watch is what finally allowed the St. Hilaire intercept-method to come into its own among small boat sailors.
