It is called Pakistanese because it is!
It belonged to the Pakistanese Army in the mid sixites.
The story?
In the mid sixties, the Pakistanese army trained with their US Homologs, in the US.
They saw the US Army military watches, and specially the TR 900 and some others, and wanted to get a few for them.
Then, the US Army gave them their supplier's details, and they got a batch of 50 or 60 of these FF, which they engraved on the case back with their military symbol, an arrow above a " P ".
The Pakistanese army also got some Omegas, Longines if I remember well, and Tissot, I think.
Best,
