At 45mm, this replica Cubitus 5821/001AR takes the two-tone steel and rose gold platform and adds a full rainbow sapphire bezel. The 5821/001A reference replaces the standard diamond bezel with graduated colored sapphires arranged around the cushion-shaped case, creating one of the most visually striking entries in the entire Cubitus catalog. Patek Philippe has used rainbow bezels sparingly across its history, and placing one on the brand’s first rectangular sport watch signals that the Cubitus is meant to compete at every level of the luxury sport segment.

Setting colored sapphires on a rectangular bezel requires custom-cut stones for the four rounded corners. Unlike a round bezel where uniform sizes work throughout, the cushion shape demands gradual size changes at each transition point.

What Collectors Notice

Rainbow bezels polarize collectors. Some consider them the ultimate expression of high watchmaking meeting jewelry, while others prefer the restraint of a plain steel bezel. On the Cubitus platform the rainbow treatment works because the 45mm case provides enough surface area to display the color gradient without crowding. The hobnail dial texture underneath adds a second layer of visual depth. Check the full Cubitus collection to compare plain steel, diamond, and rainbow options. The green dial diamond version offers a middle ground between understated and fully adorned.

This vs Other Versions

Where the standard 5821/1A keeps things clean and the diamond-set 5821/1AR adds sparkle, the 001AR rainbow pushes into outright statement territory. The colored sapphires mean no two viewing angles look identical as light moves across the bezel. On wrist it reads louder than most Patek sport watches, which is precisely the point for buyers who want maximum presence. This replica Cubitus 5821/001AR puts the collection’s boldest configuration within reach for those who favor color over restraint.
