Strap for Superocean 44

The lug width of the Breitling Superocean A1739102BA76131S is 20 mm. This measurement refers to the internal gap between the two lugs of the case and should be taken with a digital calliper directly at the strap attachment point, flush against the case, to ensure accurate fitment before purchasing an aftermarket strap.

The optimal choice depends on the intended use. For formal settings, a vegetable-tanned alligator strap with a calfskin lining at 20 mm is the most refined option. For everyday sport use, a patinated box-grain calfskin offers the best balance of durability and wrist comfort. In aquatic or high-humidity environments, a vulcanised rubber strap is the technically correct solution. A two-piece ballistic NATO strap is ideal for those prioritising lightweight wear and quick interchangeability.

The strap on the Breitling Superocean A1739102BA76131S is secured by standard 20 mm spring bars. To replace it, a soft-tipped lever tool or a dedicated springbar tool is sufficient: insert the tip into the lug hole on the side of the spring bar, compress the spring pin and slide the strap free. The entire operation is reversible within a few minutes and does not require professional watchmaker intervention.

Yes. Any strap with a 20 mm attachment and standard spring bars is compatible with the Breitling Superocean A1739102BA76131S. Milano Straps offers a curated selection of handcrafted leather, rubber and textile straps specifically suited to this lug width. For optimal fit, it is also advisable to verify the case-back curvature radius, which may require pre-curved strap ends for a clean, flush fit.

The lifespan of a leather strap depends on leather quality, craftsmanship and usage patterns. A Grade I alligator or calfskin strap in vegetable tanning with hand-finished edges can last between three and five years with regular daily wear. Prolonged exposure to perspiration, salt water or UV light accelerates deterioration. For a diving watch such as the Superocean, it is advisable to alternate the leather strap with a rubber alternative in underwater or intensive sports contexts.
