Could this be correct? Early waffle Constellation dial, GX6250 case ref, and 470 caliber movement. Movement serial # of 16.6 million dates to 1958.

Literature says GX6250 is a Seamaster reference and should have a caliber 500 case. Thanks.

Total franken. Look at that weird spacer used to make the movement fit.

Butchered multiple watches to make this monster.
