One reason put forward, is that it's based on a French clock face designed for King Louis XIV (or should that be XIIII ?
), and it's for purely for artistic reasons. It splits the clock face into three equally-sized sectors of 4 numbers, going clockwise from "I", we have 4 numbers containing only I "I" (I, II, III, IIII), then 4 numbers containing "V" (V, VI, VII, VIII), then 4 numbers containing X (IX, X, XI, XII). Using IV instead of I breaks up this ordered approach.
