Strange Unicorn watch

Look at that strange piece:

I find Unicorn watches quite interesting due to he Rolex connection. But the above piece I find a bit weird. Look at the roman numerals. The 4 o'clock position. The roman numerals are wrong (Should be IV instead of IIII). Do you think this is a fake or modified dial, or is this something watch companies did back then and I'm not aware of?

Thanks!
