Hi, Recently I've been interested in a few 12s watches with precious metal cases. I've made offers but have been told "this is xxxoz of precious xxx". Of course, they don't remove the movement, crown, crystal, etc. So...as a quick counter argument I was wondering if anyone had some very loose ideas of what an open face 14k and Platinum case might weigh as it stands alone? I know this is a stupid question since cases very so much, but what the hey. Thanks, Tom O.
