The chrono hand without question does not belong to this watch.
To me (at least) the dail (also without question) does not belong to this reference.
The phase-in period of the wide T dial started around the 3rd quarter of 1967. It simply did not exist before that.
The phase-out period of the narrow T dial lasted until the last quarter of 1967 (latest one that I have on hand is a late October 1967 105.012-66CB still with the narrow T dial).
I have yet to see a true one owner/untouched 105.012-64/65 (and I have bought & sold dozens of them) that came with the wide-spaced T dial.
