HBF Factory full ceramic case Audemars Piguet Royal Oak Offshore 26402 series 44mm watch — a flagship model designed to surpass all market versions and eliminate obvious visual flaws.
Based on continuous R&D improvements, this model aims to break technical limitations and enhance both aesthetics and wearing comfort, while maintaining strong wrist conformity and reducing noticeable differences from original references.
The case and bezel are made of imported zirconia ceramic, formed without pigments under ultra-high pressure and high temperature sintering, resulting in a dense, high-strength colored ceramic structure.
The entire case is finished using advanced CNC-level machining, with all angles precisely refined.
Each hexagonal screw is perfectly flush with the bezel surface, with strict control to ensure no protrusion or depression, representing high-end finishing standards.
The dial features the classic Audemars Piguet “Grande Tapisserie” pattern, with layered square geometry and refined surface finishing that highlights craftsmanship detail.
The crystal uses double-sided sapphire glass, and the strap is made of fluororubber for durability and comfort.
The movement is based on a 7750 modified to 3126-style chronograph architecture, featuring 12 o’clock small seconds and chronograph counters at 6 and 9 o’clock, aiming to replicate original functional layout. Each piece undergoes manual QC inspection to ensure movement stability and reliability.
A high-end ceramic chronograph-style watch focused on finishing precision, structural consistency, and enhanced wearing experience.
