Right, and when sized down to a smaller wrist it's more like 137g/162g so 25g difference. Much smaller difference than the 60g gap between a tungsten DD40 and a DJ41.
All your pics led me to pull the trigger on the same non-heavy steel QF as yours. I like the steel metal tone over the white-blueish tone of the new weight gain plated model.
Will swap the bezel, movement/dial, and caseback into a Clean 126509 case to preserve the "Au750" stamp. That eliminates all the QF case issues with the long pushers and poor bracelet/clasp, and eliminates the Clean issues with the dial and bezel.
