Timex have produced many dials that use roman numerals to tell the time. Something you’ve likely not noticed untill i point it out is that Timex roman numeral watches do not use the characters IV for 4, instead they use IIII. This is so that the numbers 4 and 6 are not confused when looking at the watch from different angles. This was a common practice across many brands that put roman numerals on the dials.

Roman numeral markers were often printed on the dial to deliver a clean and classic look. Timex did however create applied roman numerals which are featured on mid 1970s Viscounts. These look to have been roughly machine produced and are not highly finished.
