Reading a Roman numeral watch is simple once you know the three basic symbols: I (1), V (5), and X (10). The numbers 1 to 3 are written as I, II, and III. The number 4 is traditionally written as IIII on watches. From 6 to 8, you add I to V (VI, VII, VIII). 9 is written as IX (one before ten), and 12 is XII. This elegant style is the signature feature of the Jowissa Roma collection.
