Audemars Piguet Code 11:59 Perpetual Calendar 26394BC 'Aventurine'

Audemars Piguet Code 11:59 Perpetual Calendar 26394BC: Aventurine in White Gold

The Code 11:59 is AP's most debated collection, and we understand why. But when someone tells us the Code does not work, this is the one we hand them. The multi part case with its octagonal middle section only makes sense once you hold it, and with a full perpetual calendar inside it becomes a serious watch in every sense. Of all the Codes, this is our favourite.

This example has the blue aventurine dial, a glass with copper particles that sparkle like a night sky, which makes the calendar displays seem to float. It comes directly from its first owner, dates from 2023 and is offered as a full set.

Design & Movement
41mm 18k white gold case, blue aventurine dial, automatic caliber 5134 with day, date, week, month, leap year and astronomical moonphase. On a strap.

Provenance & Condition
From the first owner. Full set from 2023 with box and papers.

The Code 11:59 26394BC: the reference that wins over the doubters.
