Description
The 5821/1A reference in blue introduces a cooler palette to the Cubitus range, and this replica Cubitus 5821/1A blue 45mm pairs that dial tone with diamond-set bezels on a two-tone steel and rose gold case. Patek Philippe designated this the 5821/1AR, with “R” indicating Everose gold elements integrated into the stainless steel construction. The result is a 45mm cushion-shaped watch that balances sport-watch proportions with jewelry-level finishing. Diamond hour markers and bezel stones push the overall look well beyond the understated steel-only models in the same collection.

The two-tone construction means gold mid-links alternate with steel outer links on the bracelet. The blue dial plays well against the warm rose gold accents, creating a deliberate contrast rather than a monochrome effect.
Design & Finishing
Diamond-set Cubitus references require careful alignment because the cushion-shaped bezel presents a different geometry than round cases. Each stone must follow the curve of the rectangular form without gaps at the corners. The hobnail pattern on the dial remains visible between the applied diamond 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 rainbow bezel version takes the diamond concept further with colored sapphires replacing white diamonds.
On the Wrist
At 45mm the two-tone Cubitus carries more visual weight than its steel-only counterpart, but the integrated bracelet distributes mass evenly across the wrist. The quick-adjust clasp inherited from the Nautilus 5811 allows micro-sizing without tools, which matters on a bracelet where gold and steel tolerances need to stay precise. This replica Cubitus 5821/1A blue 45mm delivers the diamond-dress-sport crossover that the collection was designed to explore.
