Replica Patek Philippe Cubitus 5821/1A — 45 mm Black Dial, 904L Steel
The 5821/1A in steel with a black dial is the most discreet Cubitus — no rose gold accents, no colored dial, just a 45 mm stainless steel sport watch with a dark hobnail face. The 1A suffix designates the all-steel configuration with integrated steel bracelet. Black on steel is the stealth option in the Cubitus catalog, reading as serious hardware rather than jewelry. This replica Patek Philippe Cubitus 5821/1A is built in 904L steel: case, bezel, integrated bracelet, fold-over clasp.
Black hobnail dial on all-steel at 45 mm — the Cubitus stripped down to its most industrial form, where the cushion-shaped case speaks without color.
Case & Dial
45 mm cushion-shaped case in 904L stainless steel. Brushed flanks with polished bezel edges. Integrated bracelet lugs. Sapphire crystal front and display caseback. Crown at three. Without the rose gold contrast, the monochrome steel case reads as a single continuous surface — more cohesive, less ornamental than the two-tone version.
Black dial with hobnail texture. Applied steel-tone baton markers with luminous fill, matching baton hands. Date at three. The black face against steel creates a tool-watch aesthetic unusual for Patek Philippe. Under direct light the hobnail dots catch individual highlights; in ambient light the surface reads as a unified dark field.
Bracelet
Integrated 904L steel bracelet with quick-adjust deployment clasp. All links in brushed and polished steel, graduating from the case to the clasp. The full-steel bracelet carries more weight than the two-tone version — 904L is denser than standard 316L. A different tactile experience from the Nautilus steel bracelet, which follows a horizontal-link pattern.
Movement
Automatic, 28,800 vph, caliber 26-330 SC specification. 45+ hour power reserve. Sapphire caseback shows the decorated movement. SuperClone: ±8 sec/day. Full grade details on our FAQ page.
