Superocean Heritage B31 Automatic 40

The Breitling Superocean Heritage B31 Automatic 40 draws its inspiration from Breitling’s original dive watches of the 1950s, blending vintage cues with modern engineering. This 40mm model strikes a balance between classic proportions and contemporary versatility, making it a standout for those who appreciate a nod to history without sacrificing everyday wearability. Collectors are drawn to its clean, minimal bezel and mesh-style bracelet, which reference the earliest Superocean designs.

Within the lineup, the Superocean Heritage B31 Automatic 40 is differentiated by its use of the B31 caliber, a COSC-certified movement offering reliable accuracy and a quick-set date complication. The 200-meter water resistance and screw-down crown make it a functional diver, but the slim case profile and domed sapphire crystal lend it an elegance not always found in tool watches. Variants differ in dial color and strap options, with the mesh bracelet models typically commanding a premium.

Key reference numbers for this model are found under the AB2010121B1A1 family, with subtle differences in dial and bracelet combinations. Price variation is mainly driven by condition, completeness (box and papers), and whether the watch features the original mesh bracelet or the rubber strap. The B31’s value is further enhanced by its limited production compared to more common Superocean models, so examples with full sets and unpolished cases are especially sought after.
