Across them, the design changes are expressed through case materials, ceramic components, dial textures and colors, and interchangeable straps—not one specification shared by every reference.
What’s new in the Royal Oak Offshore Selfwinding Chronograph designs?
Audemars Piguet describes new 42 mm models in stainless steel, titanium, and 18-carat pink gold, with Petite or Méga Tapisserie dial motifs in different hues. The brand identifies Calibre 4404 as the selfwinding integrated flyback chronograph movement for these 42 mm novelties, visible through a new sapphire caseback. This is a family-level description; it does not establish every detail for every reference. Audemars Piguet’s collection overview distinguishes this 42 mm evolution from its 43 mm generation.
The 43 mm designs show greater variation in material and color combinations. Officially listed examples include titanium with grey ceramic and a grey-and-blue dial, and pink gold with black ceramic and a black dial. The collection listing also names stainless-steel, titanium, pink-gold, and ceramic references; it does not establish that every listed model is a new release. Audemars Piguet’s collection listing

What is the difference between the 42 mm and 43 mm Royal Oak Offshore Chronographs?
The central distinction in Audemars Piguet’s descriptions is generation, diameter, and movement—not simply a larger or smaller version of one identical watch.
- 42 mm: the described novelties use stainless steel, titanium, or 18-carat pink gold; dial motifs are Petite or Méga Tapisserie; the identified movement is Calibre 4404, with a new sapphire caseback.
- 43 mm: the collection includes varied material, dial, and strap configurations. The two detailed references here use Calibre 4401; the titanium reference page lists a 70-hour power reserve and flyback chronograph.
The overview does not provide complete, reference-by-reference specifications for all 42 mm models, so features such as water resistance, exact dimensions beyond diameter, or strap combinations should not be assumed from the family description. Nor do the stated diameters and materials establish comparative wrist fit or comfort; the available descriptions contain no wear-test evidence.

How does the interchangeable strap system fit into the designs?
Audemars Piguet describes an interchangeable strap system across the 42 mm and 43 mm offerings. The named 43 mm examples pair grey ceramic and titanium with a grey rubber strap, or pink gold and black ceramic with a black rubber strap; the latter reference also specifies an additional black alligator strap. The cited official descriptions do not establish compatibility with third-party straps, so that should be confirmed for a specific reference rather than inferred from the system’s interchangeability. 42 mm collection overview · Titanium reference · Pink-gold reference
