I've seen a couple like this sell for about USD$400.
You need to pop the back and see if it's a real 196.0360 and whether it's only a flat battery and worth fixing.

Although it's not a "collector" watch, there are still people who just like the look and buy them.
Google "Omega Constellation 196.0360" and find completed auctions/sales etc to get an idea of value.
