Actually we can skip BP as clearly being not very good, but the SWF version seems to be the best, have a look at the pictures, they got the concentric circles right as well as the two-tone lume (hands vs. markers) and the sunburst, even the engravings on the backside are very good (not that I would care very much for that). Of course the rotor of the ZF is better decorated, but IMO that does not matter the slightest bit on a closed caseback anyway. So actually my vote goes for the SWF, but I would like to make use of the wisdom of the forum, what do you guys think?
