Description
APSF Audemars Piguet Royal Oak Chronograph 26240BA Smoked Gold
By successfully cloning the Calibre 4401, APS Factory has delivered a 26240BA with the correct 12.0mm case profile and authentic sub-dial spacing.
Powered by Custom Calibre 4401 Clone
The horological core of this APSF release is the fully realized 1:1 Calibre 4401 clone. This movement eliminates the historical reliance on modified Asian 7750 movements, which forced earlier replicas to exceed 14mm in thickness. The custom architecture allows for proper integration of the chronograph mechanism, resulting in accurate 3-6-9 sub-dial positioning and a flush, instantaneous date wheel. The movement bridges are decorated with c么tes de Gen猫ve and perlage finishing to mimic the genuine Audemars Piguet aesthetic.
�� Accuracy Profile:
Regulated to approximately 卤10��15 seconds per day. The custom chronograph module requires adequate power reserve to function smoothly; engage the pushers only when fully wound.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Fully functional 12-hour chronograph, running seconds, instantaneous date
- �� Winding Direction: Bidirectional automatic winding via skeletonized rotor
Technical Specifications
THE BUILD18K Yellow Gold Plated 316L Steel
Machined to an exact 12.0mm thickness with a verified weight of 167.5g. The case exhibits the correct ratio of vertical brushing to highly polished chamfered edges.
THE DIALSmoked Gold Grande Tapisserie
Features accurate guilloch茅 texturing with a gradient that darkens toward the rehaut. Applied gold hour markers are filled with correctly tinted luminous compound.
THE BEZELBrushed Yellow Gold Plated
The octagonal bezel is secured by eight recessed, polished white gold-toned hexagonal screws, aligned perfectly parallel to the dial curvature.
THE BRACELETIntegrated AP Bracelet
Constructed with solid links and a concealed AP double deployant clasp. Articulation is tight, mirroring the stiff, structural drape of the genuine bracelet.
Why APSF for This Reference?
Many collectors ask: ��Why not ZF or other legacy factories?��
For the modern 26240 chronograph series, APS Factory holds a distinct technical advantage due to their exclusive Calibre 4401 clone. Other factories relying on A7750 movements with decorative plates result in cases thicker than 14mm and sunken date windows. APSF achieves the genuine 12.0mm profile alongside accurate sub-dial spacing, making it structurally superior.
Full Disclosure: While weighing a substantial 167.5g, this steel-core replica is noticeably lighter than the solid 18K gold genuine (which exceeds 200g). Additionally, the heavy yellow gold plating requires careful wear to prevent scratching the sharp brushed chamfers.

Collector Q&A
Q: Does the APSF Calibre 4401 have a functional flyback feature like the genuine?
A: While the APSF Calibre 4401 is a true 1:1 clone offering accurate 12.0mm case thickness and fully functional chronograph sub-dials, it does not currently support the true ��flyback�� complication. You must stop the chronograph before resetting it to avoid damaging the movement.
Q: How accurate is the smoked gold dial color compared to genuine?
A: APSF has captured the gradient transition of the smoked gold dial reasonably well. The center has a rich golden tone that fades to black at the edges. However, under direct sunlight, the genuine dial exhibits slightly more depth in the tapisserie guilloch茅 texturing.
Q: Will the 18K yellow gold plating fade over time?
A: The factory uses an advanced PVD plating process over a 316L steel core. While highly durable for daily wear, sharp impacts or heavy friction on the brushed bracelet links can expose the steel underneath. It requires more careful handling than a standard stainless steel model.
Q: Why is there a weight discrepancy between this replica and the genuine 26240BA?
A: The genuine Audemars Piguet 26240BA is crafted from solid 18K yellow gold and weighs well over 200 grams. This APSF replica uses a stainless steel core, bringing the total verified weight to 167.5g. While it feels substantial on the wrist, a trained collector will notice the density difference immediately.
