First Wristwatch Ever Made

Experts watch?
Can someone give me any information about who made the brand wristwatch POST? I have a 14kt gold watch that my father gave me in 1954 or 55. It's either 17 or 21 gems. It came with a plum-colored band cord. I never seen even one like mine, nor has any jeweler never seen anything like it, or has ever heard of the brand. It is a beautiful timepiece and still works perfectly. This means a lot to me because it was the first watch I ever owned. I would appreciate information your vendor. Thank you very much … Ruth
