I'm not regretting my decision in getting zf at all. It looks awesome on the wrist and I am willing to live with the minor flaws. The bezel is an easy fix with some patience and perseverance. Bezel pearl looks great while not that close to gen. Cg corners are another easy fix. The cg inner corners look same as gen as does the case, dial, hands, dw font.
I managed to totally centre the dial, dwo and bezel markers. My bezel is now tighter and more central. Overall it is a great watch with a full bronze case for an amazing £300.
I feel bad for guys in line for kw, you have been led on with the promise of a better watch and will be ready in 10 days, now its 1.5 months overdue.
Admittedly there have been qc issues with zf but after a service/bit of tinkering zf is a cracking watch and is currently my daily watch.
There is no doubt zf is actual bronze and I believe it is CuSn8. While kw could still turn out to be bras or bronze plated as there are no tests and no owners to clarify its material.
