Strap for SuperOcean Automatic 46 Stainless Steel / Blue / Rubber

The lug width of the Breitling Superocean A17378E71C1S1 is exactly 24mm. This generous dimension reflects the proportions of the 46mm case and requires a dedicated strap. To verify: place a calliper inside the spring bar slot, measuring the distance between the inner edges. It must be precisely 24mm.

The choice depends on intended use and personal aesthetic. For maximum technical integrity, a military NATO or FKM rubber maintains instrumental character. For balanced elegance, vegetable-tanned alligator offers noble visual contrast; warm European calf (cognac, tobacco) creates transition toward urban contexts. A deployant buckle is recommended for quality leather straps, ensuring comfort and clasp robustness.

The process requires precision. Place the watch on a soft surface with the case face down. Use a spring bar tool to gently push the lug spring bar inward, freeing one end. Extract the spring bar completely, then slide the old strap outward. Insert the new strap in the opposite direction, align the spring bar and push until both ends click into place.

Yes, any strap with a 24mm lug width is compatible. Milano Straps supplies artisanal straps in various leathers (alligator, European calf, shell cordovan) for this size, ready to ship and fully customizable. The Casati Milano atelier also offers bespoke made-to-measure service, with personal leather selection and 3-4 week turnaround, backed by 18-month warranty.

A high-quality leather strap (vegetable-tanned alligator, European calf) lasts 3-5 years with daily wear, provided correct maintenance: protection from prolonged moisture, gentle cleaning with damp cloth, conditioning with natural creams every six months. Frequent water exposure (as with a true dive watch) reduces leather durability; in such cases, NATO or FKM rubber offer superior longevity, up to 7-10 years.
