Calibre 565 — the 564 without certification

In brief

Of the three calibres Omega launched in 1966, this is the one that never went for testing. The quickset date and the 24 jewels are the 564's; the certificate is not.

Short history

The 565 came in 1966 in a trio with the 563 and the 564. It shares 24 jewels and the quickset date with the 564, though Omega never sent it through chronometer certification.
