This is the kind of AP watch I would love to own...
The total output for non-perpetual calendar timepieces by Audemars Piguet between 1924 and 1967 amounts to an incredibly meagre 176 examples.
This production is split into two “phases”, implying different movements:
- The first phase, exemplified in this post, goes from 1924 to 1954 with the vast majority of this production employing cal. 10GHSM, with one exception at the very beginning: the first calendar watch, shown below, employs cal. 10HPVM.
- Then the second phase, not exemplified in this post, switches to cal. 9/10RSQ.
Have a great week-end!

PALE YELLOW GOLD EXAMPLE FROM 1927 BELONGING TO MATTHEW BAIN
25.5 x 28.5 mm case, manual cal. 10GHSM
As
Matthew Bain states in his
dedicated article, this example is
"one of only 48 early pieces in a rectangular case with the coveted 10GHSM caliber, featuring a triple calendar, moon phases, and age of the moon (complete calendar). Cased in pale yellow gold — a rarity, as most were white gold — accounting even for the non-rectangular cases, only 35 of these were ever made in this metal."
