APS Factory Edition — Integrated Stainless Steel Bracelet
APS Factory’s execution of the 41mm Royal Oak Chronograph 26239BC represents a significant technical development in replica horology. By engineering a true integrated clone movement rather than relying on historically flawed modular 7750 bases, this edition achieves the exact 12.0mm case thickness and correct sub-dial spacing required by discerning collectors.
At the heart of this piece is the fully integrated Calibre 4401 super clone. Unlike older modular chronographs, this column-wheel mechanism ensures the date wheel sits flush with the dial surface. The power reserve operates at approximately 36 hours, providing stable daily performance.
The 41mm case is machined from standard stainless steel, carefully exhibiting the brushed/polished alternating finishing characteristic of the Royal Oak line. The black and silver dial features crisp tapisserie texturing, though it is worth noting the genuine 26239BC is cast in 18k white gold, creating a noticeable weight discrepancy against this 169g steel replica.
