Help with Piaget

[ETenebris]

I received this watch as a gift about twenty years ago, and I remember being told at the time that it was a valuable watch. Of course I know nothing about Piaget, or authentication, so I am hoping someone here might be able to tell me what the value is for this watch. Sorry for the terrible phone pic, my camera battery is dead. I will try to get better photos once it has charged.

The dial is two tone and has eleven tiny diamonds and the date in the 3 position.

Hi ETenebris

In 1979, Piaget introduced an originally styled wristwatch inspired by the sport and called Piaget Polo. The timepiece was crafted in gold and immediately became highly demanded among stars. It featured the perfectly integrated case and bracelet and the original alternation between polished and satin-brushed surfaces

I finally have more pics...can anyone tell me if this is authentic and what its value might be?
