From the front view
- the most distorted crystal looks to be my noob
- ZF inscriptions look bolder than noob and kw but I suspect this might be a focus issue
- L SWISS MADE L inscription looks smaller on noob, hard to judge as it's very close to the edge and may be distorted by crystal
- Dial cutouts and numbers/indices again hard to judge due to distortion, they all look fine to me.
- CG shape is good in all three, ZF has nicer pin, noob has nicer lever tip KW is in the middle.
- REG T.M. engraving font looks slightly too tall in ZF, very similar in KW and noob
- Crown and tube look very similar in all three versions
- Noob and ZF have sunken CP, KW has faux CP perfectly flat but hands sit too tall on the dial
- All version have wrong minute hand with too wide lume portion
From the back view
- ZF has more evident sunburst on plates
- sunburst brushing on gears is too wough on ZF, the polished effect on the teeth looks better than the others though
- Swan neck shape looks very similar if not the same
- Micrometric screw is worse in noob, with smaller head. Both kw and ZF look good, I slightly prefer KW becaus the head is detached from the swan neck (more credible effect)
- Noob obviously does not have Y incabloc, nice feature in both ZF and KW
- OFFICINE PANERAI FIRENZE engraving look very similar in KW and ZF, more yellow and less crisp in noob.
- Caseback engravings look deeper in KW, nicer but maybe too deep. It probably is the pic, but the serial number in ZF looks too rough, almost like laser engraved.
