Waar staat dat VFA voor? Mooi horloge!
Ik heb het al: "Very Fine(ly?) Adjusted!
VFA stands for “Very Fine Adjusted”. When these watches were sold in the early 1970’s, they were regulated to +/- 2 seconds a day, and guaranteed to be accurate to within 1 minute a month for the first two years of ownership. Quite simply, the absolute pinnacle of mechanical watchmaking of their time.
