APS Factory Edition — Integrated Steel Bracelet
The APS Factory iteration of the 26331ST resolves the historical thickness issue that previously plagued Royal Oak Chronograph replicas. By utilizing a newly developed movement architecture, APS successfully brings the case profile down to 11.2mm, nearly identical to the genuine 11mm specification. This represents a significant technical benchmark within the community, eliminating the top-heavy wearability of older variants.
This model is powered by the APS Clone Calibre 2385. Unlike older platforms that relied on unmodified, bulky 7750 bases, this integrated approach allows for proper sub-dial spacing at 3, 6, and 9 o’clock while maintaining a slim profile. The power reserve is rated at approximately 36 hours, providing reliable daily performance.
Crafted from solid 316L stainless steel, the 41mm case features the signature alternating brushed and polished finishing on the bezel and lug chamfers. The dial exhibits a deep blue Grande Tapisserie pattern with contrasting silver rhodium-toned sub-dials, closely replicating the genuine light-play and geometric texture.
