Description
BBAF Patek Philippe Cubitus 5821/1A-001 Olive Green
A dimensionally accurate execution of the 5821/1A, prioritizing case thickness over true clone movement architecture.
Powered by Modified Caliber 26-330 S C
BBAF opted for a reliable Miyota 9015 base to achieve the ultra-thin 8.3mm case requirement. The bridges and rotor are heavily decorated with faux perlage and côtes de Genève to emulate the genuine 26-330 S C. While visually compelling through the sapphire caseback, the unidirectional winding rotor exhibits a high spin velocity typical of this base caliber, prioritizing slimness over absolute mechanical parity.
Rated at ±8–12 s/day, consistent with regulated Miyota 9015 base architectures.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Sweep seconds, date display at 3 o’clock
- ✅ Winding Direction: Unidirectional (clockwise)
Technical Notice: Clone 324 Movement
The replica market currently produces only the Clone 324 movement. Even if movement bridges are engraved “330”, the mechanism operates as Clone 324.
Practical implication: The seconds hand does not stop when setting the time. This is correct behavior for this movement and ensures maximum long-term stability.
Technical Specifications
Constructed to an exact 8.3mm thickness, the case weighs 129.2g, maintaining a balanced feel comparable to the genuine integrated sports model.
Features horizontal relief embossing with an accurate olive green lacquer application. The date window framing exhibits sharp finishing under macro inspection.
Distinctive geometry with prominent vertical brushing on the flat surfaces and high-polish chamfered edges, accurately reflecting Patek’s alternating finish techniques.
Fluid articulation of the links with a secure lockable adjustment system. Endplay tolerances are tight, avoiding unwanted lateral play.
Why BBAF for This Reference?
Many collectors ask: “Why not wait for a custom clone movement?”
BBAF’s decision to use a slim base caliber allows them to hit the true 8.3mm case thickness immediately. Competing early prototypes utilizing thicker clone movements fail to capture the elegant, ultra-thin profile that visually defines the Cubitus on the wrist.
Full Disclosure: The Miyota 9015 base movement features a unidirectional rotor that is audibly louder than the genuine article during rapid wrist movement.

Collector Q&A
Q: Why did BBAF use a Miyota 9015 base instead of a true Patek clone movement?
A: A true integrated clone movement capable of fitting inside an 8.3mm case does not yet exist for the Cubitus reference. The Miyota 9015 was selected specifically for its slim architectural profile, allowing the factory to achieve the correct 1:1 case thickness immediately.
Q: Is the olive green dial tone accurate to the genuine 5821/1A?
A: BBAF has captured the dynamic sunburst effect well, though under direct, harsh lighting, the replica dial exhibits a slightly warmer green hue compared to the deep, muted olive of the genuine lacquer application.
Q: Does the date wheel font match the genuine Patek typography?
A: The date wheel utilizes a custom overlay to mimic the Patek Philippe font. The typography is generally accurate in its serif design, though the print thickness is marginally heavier than the genuine counterpart.
Q: Is the movement rotor exceptionally loud on this model?
A: Yes. Due to the Miyota 9015 base architecture, the unidirectional rotor spins freely in the non-winding direction. This results in a high spin velocity and an audible whirring noise during sudden wrist movements, which is a known characteristic of this release.
