          BBSF Audemars Piguet Royal Oak Perpetual Calendar 26613ST

          The BBSF 26613ST serves as the current technical standard for functional calendar replicas, balancing complex modular mechanics with precise case finishing.

          Powered by Clone Caliber 5134

          The clone caliber 5134 operates via a base automatic movement fitted with a comprehensive calendar module. This architecture allows the sub-dials to function via the recessed pushers located on the case flanks, mirroring the interaction method of the genuine caliber. The balance wheel is regulated via a standard index system, and the skeletonized rotor is finished to replicate the OEM oscillating weight.

          �� Accuracy Profile:

          Standard regulation yields an accuracy of 卤10��15 s/day. The additional drag from the calendar module can cause slight variations in amplitude as the date mechanisms engage near midnight.

          • �� Power Reserve: Approximately 36 hours
          • �� Complications: Day, date, month, week indicator, and moonphase
          • �� Winding Direction: Bidirectional automatic winding

          Technical Specifications

          THE BUILDStainless Steel

          Verified at 11.4mm thick with a specified measurement of 186.1mm, the case demonstrates precise brushed/polished alternating finishing. The integrated bracelet fit against the case flanks shows minimal endplay.

          THE DIALGrand Tapisserie

          The Turquoise Blue dial achieves high visual accuracy, featuring crisp sub-dial printing and applied hour markers with consistent luminous fill.

          THE BEZELStainless Steel

          The iconic octagonal bezel is secured with polished hexagonal screws, sitting flush against the mid-case with sharp, defined chamfered edges.

          THE BRACELETIntegrated Steel Bracelet

          Constructed with solid links and featuring the AP double deployant clasp. The tolerances on the clasp mechanism provide a secure, tactile engagement.

          Why BBSF for This Reference?

          Many collectors ask: ��Why not APSF?��

          While APSF excels in standard three-hand 15500 and 15400 models, BBSF has dedicated specific R&D to the 5134 modular complication. The BBSF version provides a functional sub-dial layout that correctly interfaces with the recessed case pushers, a technical hurdle that other factories have historically struggled to overcome.

          Full Disclosure: The verified 11.4mm case thickness is notably larger than the genuine 9.5mm profile, a necessary physical compromise required to house the cloned modular calendar mechanism.

          Collector Q&A

          Q: Does the BBSF 26613ST feature a fully functional perpetual calendar?

          A: The sub-dials for the day, date, month, and moonphase are functional and adjusted via the recessed pushers on the side of the case. However, it operates mechanically as an annual or complete calendar rather than a true perpetual calendar, meaning manual adjustment is required for leap years and shorter months.

          Q: How does the case thickness compare to the genuine Audemars Piguet?

          A: The verified thickness of the BBSF replica is 11.4mm. The genuine Audemars Piguet 26613ST measures 9.5mm. This 1.9mm variance is a known technical limitation across all replica perpetual calendars, as the clone movement requires additional vertical clearance for the calendar module.

          Q: Is the turquoise dial color identical to the OEM version?

          A: BBSF has achieved a highly accurate base tone for the turquoise dial. However, under direct natural sunlight, the replica lacks the ultra-fine metallic luster and depth found in the genuine Audemars Piguet lacquer application.

          Q: What is the primary mechanical concern with this specific replica?

          A: The modular nature of the clone 5134 caliber makes it delicate. Engaging the recessed pushers between the hours of 9:00 PM and 3:00 AM can severely damage the date driving wheel. Always set the main time to 6:00 before making any calendar adjustments.
