It seems to have been used in the same date range so why the difference? Was it specific to country codes, models, etc.? Curious any info you guys can share.
Thanks!

Up till 1960 Rolex used the word SWISS then dials were Radioactive Radium from around early 1960 on Rolex used T.Swiss.T less than 277 MBq (7.5mCi) and Swiss <T25 less than925 MBq (25mCi)on there dial depending on how much radioactivity they had from 1960 till mid/late 1998.Swiss only dials were then used with Luminovor from 1998 to 2000, then after 2000 back to Swiss Made with Superluminovor. But Superluminover was just renamed Luminover to mark factory location change as the paint is made by Nemoto a Japanese luminous paint maker. Now they moved a part of its factory to Switzerland in 1998 in Joint-ventured with RC-Tritec AG the change from Tritium to Luminover.But this was to mainly establish Luminova AG Switzerland for supplying Luminova to all the Swiss watch industry including Rolex and most major brands.Later the name was changed to super-luminover and many other names for basically the same product under various names but all basically the same paint with a slightly different colour pigments.
