Fantastic write up...well done. I've looked at and handled many gen 16610s in the last 3 years and the things that used to give away a TC were in the more recent (late 2014 model) v6 were:
1. bezel feel and look
2. Bezel insert pearl (even in the v2 bezel)
3. non-capped pinion
4. No Dimple on the clasp Spring bar
5. Slightly blue tinted AR on crystal
6. Higher mid-link on the SEL
7. setting the time/date on the TC movement
some of these points are obscure details that only die hards In the gen world would be aware of.
Looks like the v7 improves on the following:
1 (to an extent), 3, 4, 5, and 6.
if the v7 extreme version addresses point 1, and a gen bezel insert is installed,
points 1 to 6 would have been addressed, leaving only point 7 outstanding.
that's an amazing improvement !
Point 7 is more complicated to address, with the main options either to install a serviced and modded (with gen parts) yuki 3135 or SA3135 movement. The first option is costly and the second option is potentially less reliable than TC's movement, is that correct?
are there any viable replacements to TC's movement in terms of "correctness" and reliability?
