Omega Seamastee Polaris Bezel

I have recently seen more and more Omega Seamastee Polaris watches missing their bezel. I understand it is 18k solid gold and about 2mm thick. I know it has a very distinct shape and I was wondering if anyone knew how much the bezel weights on the 32mm or any sized Polaris please. I am curious as to the value of the actual watch and obviously the gold plays a part in that.

Thank you
