Hi Joe-
Yes, all the watches were round case/dial. There were no issued square/rectangle watches, though some sellers on Ebay would love to sell you one. There were definitely a lot of PP rectangle type watches in use at the time, but these were not issued watches.
Watches are like any other field/personal gear item; some were issued, some were private purchase. The issued one's are easier to identify because they were mil-spec and had serial numbers and property stamping.
But proving that a privately purchased watch was actually worn/used in the field is difficult, just like with PP knives, daggers, rings, etc.
