Designated AB2010121B1A1, this Breitling Superocean Heritage replica carries the line’s vintage design language, with a black dial mounted on a stainless steel mesh bracelet. The 42mm case retains the domed sapphire crystal and vintage-inspired proportions that define the Heritage sub-line, while the woven steel mesh adds weight and a more substantial wrist presence compared to the rubber-strap versions. The black dial uses applied luminous indices at each hour position, and the unidirectional bezel, its black ring styled on the genuine’s ceramic, provides the standard 60-minute dive timing scale. Every element points toward a dive watch that references mid-century originals while meeting current construction standards. Our guide describes the vintage look of the Superocean Heritage in more detail.

The steel mesh bracelet is what distinguishes this reference from the rubber-strap AB2010121B1S1, which shares the same 42 mm case and black dial. Breitling calls this woven design the Ocean Classic mesh, and its tightly knitted steel gives the bracelet visual texture without the uniform mirror finish of a dress watch.

Clone Cal. B20 and the Chronometre Print

The automatic movement inside the AB2010121B1A1 is a clone Cal. B20 that stores about 55 hours, against 70 hours for Breitling’s own COSC-certified B20. The Chronometre Officiellement Certifie line on the dial is copied from the genuine; this clone carries no chronometer certificate. A date window at six o’clock provides the only complication beyond time display, keeping the dial clean and focused on its core readability purpose. The steel bracelet version runs a different calibre from the yellow-dial Superocean A17375211I1S1, a time-only Superocean on a clone Cal. Breitling 17, and the visual character could not be more different. Browse the full Superocean collection for the complete range of dial and strap configurations available in this size.

Superocean Heritage Replica in Black on Mesh

Among Heritage Superocean variants, the black-dial-on-steel combination represents the most conventional choice, which also makes it the most versatile. The neutral palette transitions from weekend sportswear to daily attire without any visual friction. On its mesh bracelet, the black B20 Heritage suits a desk and a dock equally well.
