The Patek Philippe Cubitus 5821 style clone shown here is the iced blue version: white-metal look, baguette-set bezel and stones running down the flanks and bracelet. A navy blue dial introduces a cooler palette to the iced Cubitus range, and this Cubitus replica pairs that dial tone with a baguette-cut stone-set bezel on a white-metal case with pavé-set flanks and bracelet. Patek Philippe’s own blue Cubitus is the 5821/1AR-001 in steel and 18k rose gold without any stones; this factory variant keeps the blue but drops the gold, so there is no rose gold anywhere on it. The result is a 45 mm square-cased watch that balances sport-watch proportions with jewelry-level finishing. Plain luminous batons on the dial and stones everywhere else push the overall look well beyond the understated steel-only models in the same collection.

The iced construction means every link of the bracelet is covered in small pavé-set stones, with no gold-tone links anywhere. The navy dial plays well against the white stones, creating a deliberate contrast rather than a monochrome effect.

Setting Stones on an Octagonal Bezel

Stone-set Cubitus variants require careful alignment because the octagonal bezel presents a different geometry than round cases. Each baguette must follow the straight sides of the square form without gaps at the angled corners. The horizontal embossed stripes on the dial remain visible between the luminous baton indices, maintaining the tactile quality that defines the Cubitus aesthetic. For a look at the full range, browse the Cubitus collection where two-tone and mono-metal variants sit side by side. The pavé-dial version with rainbow indices takes the stone-set concept further, covering the dial too and moving the colour onto the hour markers.

Weight and Fit of a Fully Set Bracelet

At 45 mm the iced Cubitus carries more visual weight than its steel-only counterpart, but the integrated bracelet distributes mass evenly across the wrist. Sizing is done by removing links, and it is worth doing carefully, because a fully set bracelet that sits loose will roll and catch its stones on cuffs and desks. This replica Cubitus is a dress-sport crossover that Patek itself never offered, and the dark dial keeps it easier to read than the pavé version.
