BBSF Edition — Integrated Steel Bracelet
The BBSF iteration of the Royal Oak Perpetual Calendar 26606ST represents a significant technical leap over previous replica generations. By moving away from heavily modified base calibers with faux sub-dials, this release features a dedicated clone movement that supports fully operational calendar complications. It stands as a strict mechanical benchmark for collectors evaluating high-complication Audemars Piguet replicas.
Powered by the clone Caliber 5134 automatic movement, this piece accurately maps the day, date, month, leap year, and moonphase to their correct sub-dial positions. The central week-indicator hand functions properly, advancing as intended. Due to the complex gear train required for these complications, the power reserve yields approximately 36 hours under normal wearing conditions.
The case is machined from stainless steel, measuring 41mm in diameter with a verified thickness of 11.4mm, bringing the total weight to a substantial 180g. The Grande Tapisserie dial is executed in a precise forest green tone, contrasting sharply against the alternating brushed and polished finishing of the iconic octagonal bezel and integrated bracelet links.
