Bokey TimeThe upgraded Audemars Piguet Royal Oak Offshore 26420 series is a newly refined edition.
Newly developed 43mm case (upgraded design)
Unlike the previous 44mm versions based on the older 26400 case, this model features a completely new case design. It is more ergonomic on the wrist and presents more refined finishing details. The case includes prominent polished bevels and measures 43mm × 15.6mm. The redesigned case is carefully adjusted to accommodate a slightly larger upgraded movement, ensuring better proportional balance and visual refinement.
Upgraded date display system
Through movement modification, the date display has been optimized to match the original large-date visual effect. The date window has been repositioned closer to the dial edge, while the hands have also been subtly refined for improved visual alignment.
Movement
Powered by a modified Dandong 7750 (small seconds at 6 o’clock) upgraded to a Calibre 4401-style architecture with a larger bridge plate design. This ensures improved aesthetics and more stable performance.
Case material
Constructed from Japanese 316L stainless steel, providing a brighter and more refined metallic finish compared to standard 306 steel commonly found in lower-tier versions.
Bezel & crystal
The bezel uses imported Korean ceramic, available in black, blue, and green variants. The crystal is made of sapphire glass for enhanced clarity and scratch resistance.
Strap options
Equipped with imported fluororubber straps for superior comfort and wearability. Leather versions use top-layer calfskin, while fabric straps are made from leather-backed textile construction rather than pressed synthetic materials.
Dial upgrade
The dial texture is refined through CNC slow milling (not oil-pressed stamping), resulting in a sharper and more defined “waffle pattern” structure. The signature geometric square pattern is now interconnected by cross-link elements, enhancing depth and luxury appearance.
This model represents a high-end luxury sports chronograph, combining refined aesthetics and mechanical performance. It is positioned as a premium recommendation for masculine multi-functional mechanical watches, ideal for gifting and collection.
