The Patek Philippe Cubitus 5821/1A-001 is a bold new square-cased sports watch in stainless steel, featuring a vibrant sunburst olive-green dial. Our high-grade Super Clone precisely mirrors its look and feel: a 45mm 316L steel case (alternating brushed and polished finish) houses the Swiss-made clone of Patek’s automatic Caliber 26‑330 S C movement (4 Hz, ~35–45 h power reserve) with date at 3 o’clock. It comes on an integrated steel bracelet with solid links and a folding clasp. This clone delivers the same luminescent white-gold markers, iconic “garage-door” dial pattern, and real-sapphire crystals as the original, offering the Patek Cubitus experience at a fraction of the price. Key selling points include its 1:1 case dimensions, high-accuracy automatic movement, flawless finishing, and premium materials – all engineered to satisfy enthusiasts seeking a luxury sports watch replica.
- Case: Precision CNC-machined 316L stainless steel case (45 × 45 mm square). Alternating surfaces—brushed on the top facets, polished on the chamfered edges—mirror the original Cubitus’s Art-Deco luxury aesthetic. The case is about 8.3 mm thick (matching Patek’s spec) and features screw-down caseback and crown (for protection and durability). A substantial feel (over 150g) and solid construction ensure longevity.
- Bezel: Fixed square bezel in matching 316L steel, fully polished. The crisp edges and flawless machining maintain the Cubitus’s signature stepped outline. There is no rotation (timing functions); instead, the fixed bezel provides the squared-off, formal look intrinsic to the design.
- Crystal: Sapphire crystal (front) with anti-reflective coating. This hard, scratch-resistant glass preserves the pristine dial view over time and reduces glare, just like the genuine Cubitus. A display sapphire back (or steel back on some clones) showcases the movement. Both crystals ensure durability and clarity.
- Dial: Deep olive-green sunburst dial with horizontal embossing (often called “garage-door” texture). Applied white-gold baton hour markers and hands are faceted and filled with Swiss Super-LumiNova for bright blue glow at night. The dial layout includes a date window at 3 o’clock. Every marker and font is sharply printed or applied. Note: Some clones may show a slight hue variation in green or use a standard date font (the genuine’s “anniversary” font is uncommon in replicas). Still, the overall dial appearance—sunburst pattern and color tone—closely mimics the original.
- Movement: Swiss-made automatic clone of Patek’s Caliber 26‑330 S C. It beats at 28,800 vph (4 Hz) and is adjusted to within ±8 s/day (roughly matching Patek’s chronometer-grade spec). Functions are fully implemented: hour/minute/seconds and an instantaneous date. The clone’s bridges are decorated with Geneva striping, and the rotor is engraved – just like the authentic movement. Owners report that the Miyota-based clone 26-330 winds smoothly and holds roughly 35–45 h power reserve. It is reliable and far more stable than typical low-grade movements.
- Bracelet & Clasp: Integrated 316L steel bracelet with solid three-link construction (the center link is polished, outer links brushed). It attaches seamlessly to the case, emphasizing the Cubitus’s sculptural lines. The fold-over clasp is stamped with Patek-style logo and uses push-button releases. A built-in micro-adjust system lets you fine-tune the fit by a few millimeters without tools. The bracelet and clasp feel robust—much like the original’s—thanks to precise link alignment and screw pins. Overall, these details give the clone a convincing replica of the Patek Cubitus bracelet experience.

FAQ
Q: What movement does the Super Clone use and how accurate is it?
A: The clone uses a Swiss automatic “Super Clone” movement mimicking Patek’s Calibre 26-330 S C. It keeps time within a few seconds per day. Explanation: Top Cubitus replicas (like PPF/3K versions) install a fully jeweled automatic clone movement. You get real winding and seconds sweep, just like the original. Expect around +/-4–6 s/day accuracy after regulation – far better than cheap quartz. The movement also winds itself via rotor and stores ~35–45 hours power (like the genuine). Many users confirm the replica’s rotor spins freely and the watch runs smoothly. In short, you get all genuine functions (time and date) with automatic convenience.
Q: Is the green dial color and date font exactly like the genuine Cubitus?
A: Premium clones boast excellent fit and finish. The case edges are sharp, the bracelet links align evenly, and the polish/brushing work is very good.Explanation: Many owners praise early Cubitus replicas for their solid feel. In the referenced review, the rep’s “fit/finish” and applied markers were commended
Q: Is the Cubitus clone comfortable to wear given its 45mm size?
A: Yes, the 45mm square Cubitus wears well on medium to large wrists. Its integrated bracelet and thin profile (about 8.3 mm) keep it from feeling bulky. Explanation: Although 45 mm sounds large, the diagonal case width (corner-to-corner) spreads the size, and the short lugs prevent overhang. The integrated bracelet tapers and sits flat, so the watch conforms comfortably. Most reviewers find the weight and thickness balanced. Like Patek’s own sports models, it has a substantial presence without being unwieldy. If you’ve worn a Nautilus or large Aquanaut, this will feel similarly comfortable.
