Strap for SuperOcean Automatic 46 Stainless Steel / Black / Bracelet

The lug width of the Breitling Superocean A17378211B1A1 is 24 millimetres. This measurement is essential when purchasing compatible straps, as it ensures correct assembly between the case lugs and the strap. To measure the lug width, position a tailor's measuring tape on the inner case between the two lug attachments.

The ideal strap depends on intended use. For diving and sports, vulcanised rubber guarantees waterproofing and maximum grip. For business or formal contexts, alligator in brown tones or shell cordovan offers elegance. A NATO in regenerated fibres represents the perfect compromise between versatility and character. The choice should balance aesthetics, practicality and water resistance.

Strap replacement requires a specific tool (spring bar tool) and a few minutes. Press the thin button of the spring bar gently to release the internal spring, then extract the old strap. Once removed, align the new strap with the lugs and push the spring bar until it clicks into place. Work on a clean surface and use anti-scratch tweezers for safety.

Any strap with a 24mm lug width is compatible with the Superocean A17378211B1A1. A wide range is available: alligator, calf, cordovan, NATO, canvas and rubber, all customizable by specialist artisans like Casati Milano. Technical compatibility is guaranteed by standardised lug width, allowing unlimited aesthetic personalisation without construction compromises.

Durability varies by material and use. Premium alligator with vegetable tanning lasts 3-5 years with regular care. Shell cordovan resists 4-6 years thanks to superior fibre density. Vegetable-tanned calf lasts 2-4 years. Vulcanised rubber, being synthetic, can last 7-10 years without aesthetic degradation. Exposure to humidity, perspiration and sunlight accelerates ageing of any material.
