Hello everyone!

I was hoping to get some info on this nice Movado watch.

It has 14K bracelet and back.

The numbers are:

66 5090 172


It has a Zenith movement 2320; 17 jewels.

Is the first number the type of metal and the third number the movement? If so what is the middle number?

Is there any website to look up these kinds of vintage watches?

It is not running right now. Is it worth fixing? I hate to just scrap it for the gold. Thanks in advance!
