Actor Damian Lewis spotted wearing a Audemars Piguet

Season 4 of Billions gave viewers plenty of wrist action from Bobby Axelrod, and one of the standout pieces was the Audemars Piguet Royal Oak Offshore Camouflage ref. 26400SO.OO.A335CA.01 strapped to Damian Lewis's wrist. The wardrobe department clearly understood the character: a self-made billionaire with no interest in understatement. The Offshore Camouflage delivers exactly that brief.

Audemars Piguet introduced the 26400SO as part of a limited run that expanded the Royal Oak Offshore's already bold language into tactical-wear territory. The 44 mm case is rendered in smoked black ceramic — a material chosen for its scratch resistance and deep, non-reflective finish — while the octagonal bezel is crafted from forged carbon, giving it an irregular, almost geological surface texture that changes appearance under different light. The camouflage dial itself is produced through a multi-layer printing process on a base that integrates khaki, olive, and black tones. Beneath the dial sits the Calibre 3126/3840, a self-winding movement with column wheel chronograph and a 50-hour power reserve, running at 21,600 vph.

From a collector standpoint, the Royal Oak Offshore Camouflage occupies an interesting position. It is limited in production and represents one of the more material-forward experiments AP conducted on the Offshore platform during the early 2010s, before the brand's more recent ceramic and titanium sports watches arrived to compete for attention. The combination of ceramic, forged carbon, and a fabric strap sewn with Kevlar thread makes it a legitimate showcase of manufacture-level finishing applied to a sporty, almost military brief.

Damian Lewis wore the reference throughout his run as Bobby Axelrod, a character whose wrist game was consistently monitored by watch enthusiasts tuning in as much for the horology as the drama. The 26400SO reads as an ideal prop choice: expensive, rare, and deliberately intimidating — everything Axelrod projects.

On the secondary market, the Royal Oak Offshore Camouflage 26400SO commands a healthy premium over its original list price, driven by limited availability and sustained demand from collectors who prize unusual dial treatments. Expect grey-market prices to sit meaningfully above retail, reflecting both the watch's scarcity and the enduring commercial strength of the Offshore name.
