Ninja01 from Seikoholics was kind enough to indicate a mistake in the following sentence:
"When the VFA was sold in the early 1970s it was advertised to have an accuracy of +-3 seconds per day."
According to the database information by Kobayashi Seiya (KSeiya) and to quote Ninja01:
"Well, close, but no cigar!! It was actually a more impressive +-2 seconds & that started in 1968 according to my info!"
According to the KSeiya table the GS VFA was the most accurate movement ever manufactured by GS Pre-1976/77.
