One Movement, Two Personalities
AP's W&W 2026 presentation is anchored by the Calibre 7139 — the brand's new openworked perpetual calendar with single-crown adjustment. Rather than present it in one case, AP deploys it across two distinct architectures: the Royal Oak (Ref. 26685XT) and the round Code 11.59 (Ref. 26443NB).

Why the Round Case Changes Everything
The Code 11.59's double-curved sapphire crystals and case-in-case construction create a more intimate, jewel-like stage for the Calibre 7139. The movement fills the dial space more dramatically — no octagonal bezel geometry competing for attention. For collectors who find the Royal Oak too sporty, the Code 11.59 perpetual calendar wears equally well with a suit.
The crown-only adjustment is the same breakthrough as the Royal Oak version: any perpetual calendar function — day, date, month, leap year, moon phase — correctable via the crown alone, with no recessed pushers. It is the most user-friendly perpetual calendar ever made, now visible in full skeleton form.
Freddy's Verdict
The Code 11.59 has always divided opinion. But housing the Calibre 7139 makes it genuinely compelling — a round, openworked perpetual calendar with the most thoughtfully designed correction system in the industry. If you've been waiting for a reason to take Code 11.59 seriously, this is it. Price TBD — expected above CHF 180,200 of the Royal Oak given precious metal options.
