Strap for Superocean Heritage B31 Automatic 40 Kelly Slater / Rubber

The Breitling Superocean Heritage AB31101A1C1S1 has a lug width of 20mm. This is the critical measurement to verify before purchasing any replacement strap: only a strap with a 20mm attachment will fit correctly without lateral play or undue stress on the lugs.

The answer depends on intended use. For formal or business settings, a vegetable-tanned alligator strap in 20mm complements the ceramic and stainless steel case admirably. For marine or sporting use, a ballistic nylon NATO or vulcanised rubber strap offers water resistance and ease of maintenance. A dark navy bombé calf leather strap represents the most versatile intermediate option.

Strap replacement requires a springbar tool — a thin-tipped instrument used to compress the springbars within the lugs. Insert the tip into the gap between the strap and the lug, compress the springbar and slide the strap free. The process takes approximately two minutes per side and poses no risk to the case when performed correctly on a soft surface.

Yes. Any strap with a 20mm attachment width is technically compatible with the Breitling Superocean Heritage AB31101A1C1S1, provided the overall length suits the wearer's wrist and the buckle or deployant clasp is sized appropriately at 18mm or 20mm. On milanostraps.it, the catalogue is organised by lug width: filtering for 20mm displays all models compatible with this reference.

The lifespan of a leather strap depends on tanning quality, frequency of wear and exposure to moisture and perspiration. A vegetable-tanned alligator strap worn daily without prolonged water contact will typically retain its structure for two to four years. Shell cordovan tends to last longer due to the compactness of its fibres. Leather straps are not suited to aquatic use: for water exposure, NATO or rubber should be preferred.
