Thats a great review, thanks for sharing. Some highlights for me. ?.......
The detailed pics of the dial fonts clearly illustrate the many differences in font styles and spacing even across the same gen series!
Look at the different M fonts in the three Swiss Made pics alone? The same can be seen in several other characters in the main dial text.
I am really not clear why the kh dial is thought to be the best TC dial, as it has as many differences, as the earlier TC dial and to the naked eye on the wrist none can really be seen? Some early TC dial batches had QC issues, but a properly QC'd dial is also superb.
I completed a detailed review of my gen PJ coded 2008 bracelet, against my TC V3/V4 PJ bracelet and it really is very very close in detail, form, feel and finish.
Many gen bracelets do not have the 93250 stamped on the back in later series so this is not an issue.
Personally I think your crown guard analysis is superb, but what it does also show is why a gen crown upgrade is worthwhile? You can see in the bottom picture it really does make a difference and it eliminates the slipping clutch issue with many TC crown springs.
Thanks again for a brilliant insight and all of the above is meant to add some value to your great analysis.
I vowed for years that I would never wear a rep modern Rolex sub, but my BK TC franken changed all of that!
ENJOY YOURS :-)
