I have come across this particular watch as being referred to as an officer's watch, despite it not having a hinged caseback cover and that springbars are used instead of the screw-in type.
How apt is association versus that of the 5053? The similarities seem only to be the Arabic font used and the lug design that follows the 5053. I don't find the 5119 and 5120 being associated in the same manner if case design is the important consideration.
Thanks!
