Strap for Superocean 42

The lug width of the Breitling Superocean A1736402BA31428X is 20mm. This measurement is taken between the two lugs of the case using a calliper and is the key parameter for selecting a compatible strap. A strap of a different width will not fit correctly and may cause damage to the lugs or result in unwanted play.

The ideal choice depends on intended use and aesthetic preference. For everyday sporting wear, a 20mm vulcanised rubber or grain calf leather strap is the most coherent option for a diver of this nature. For more formal occasions, an alligator strap with vegetable tanning creates a refined and deliberate contrast. A ballistic nylon NATO strap remains the most practical and versatile solution.

The Breitling Superocean A1736402BA31428X features a proprietary integrated attachment system. Strap replacement requires a fine-tipped spring bar tool, or the assistance of a watchmaker or specialist atelier. Before purchasing an aftermarket strap, it is advisable to verify that the keeper thickness is compatible with the Breitling case profile, which tends to have closely set lugs.

Yes. The Breitling Superocean A1736402BA31428X takes a standard 20mm strap, for which a wide range of aftermarket options exists. Milanostraps.it offers a curated selection of handcrafted leather, rubber and textile straps specifically suited to this lug width. Straps with a shaped or slim keeper are recommended to ensure proper fitment against the case.

The lifespan of a leather strap depends on the quality of the tanning, hide thickness and frequency of use. A high-quality vegetable-tanned leather strap, kept away from immersion and heavy perspiration, typically lasts between two and four years with regular wear. Casati Milano straps carry an 18-month warranty against manufacturing defects. For a diver such as the Superocean used in water, a rubber or NATO nylon strap is the more technically appropriate choice.
