Strap for Superocean 44 Special Stainless Steel / Volcano Black / Rubber

The lug width of the Breitling Superocean Y1739310.BF45.227S is 22mm. This measurement is taken by placing a ruler between the lugs at the 6 o'clock side of the case: the internal distance between the two lugs determines the correct strap size. All 22mm straps in the Milano Straps catalogue are fully compatible with this reference.

The ideal strap depends on intended use. For sporting or diving contexts, a vulcanised rubber strap in 22mm is preferable — waterproof and UV-resistant. For everyday elegant wear, vegetable-tanned calf leather or alligator belly with its natural grain complement the 44mm steel case effectively. A ballistic nylon NATO strap is well suited to a casual, functional register.

To replace the strap on the Breitling Superocean Y1739310.BF45.227S, a dual-tip springbar tool is required. Insert the tip into the springbar recess, compress the spring and slide the strap free from the lug. Care must be taken to avoid scratching the case. If unfamiliar with the process, it is advisable to consult a watchmaker or visit the Casati Milano atelier.

Yes. Any strap with a 22mm lug width and a curved or straight end compatible with Breitling Superocean lug geometry is interchangeable. Milano Straps crafts bespoke straps specifically calibrated for Superocean lugs, with shaped ends to ensure optimal fit and no play. It is important to verify the total length (standard 75/115mm) to suit the wearer's wrist circumference.

The lifespan of a leather strap depends on tanning method, usage and maintenance. A quality vegetable-tanned calf strap worn daily, kept away from prolonged exposure to water or perspiration, typically lasts 18 to 36 months before showing structural fatigue. Alligator leather, owing to its denser natural fibre, can exceed 3 years with periodic conditioning. Milano Straps provides an 18-month guarantee against manufacturing defects on all handcrafted straps.
