Calibre 752 — the 751 without the certificate

In brief

No chronometer certificate. That is the whole difference between the 752 and the 751 — same quickset day-date, same 24 jewels, same corner of the 75x series.

Short history

Three calibres came out of that block of the family in 1967 — the 750, the 751 and this one — all carrying the same day-date complication. The 752 is the variant that never went for certification.
