·I'm familiar with that fella's website. I'm also quite certain that white was produced every year thru the 1680 run. However this is all academic as it will hardly matter with the watch in question. ANY genuine 1680 dial will do and fit.
I probably will not convince you, but just for posterity, here is another reference showing that white sub dials started in the high 3M range (close to 4M, 1976ish). Obviously the red sub dials go back to the low 2Ms (1970ish). There are also some interesting references linked in this thread.
