.. it is a funny observation, for me as well :
I think I've tried about 6 or 7 different straps, trying to match them to various dial components
of my (only) TTP 68 - I know, I know - not the same ..
- And after a 360 degrees, I re-landed again with the original strap, which
color- and appeal-wise still is the best, at least for me..
The downside is, it does not quite have that quality, also not the wear-comfort, somehow
Unfortunately I had missed the ss-edition of the TTP 65, so no field
for trying the colored ones..
But she is always there, and I wear her at least one to two days per 2 weeks..
Finally, of course this is not quite the "real thing", as some would say,
- for me she was & is still one of my most favorite pieces.
Best, hs
