Strap for Superocean Steelfish

The lug width of the Breitling Superocean A1739010B772 is 22mm. This measurement is taken with a digital calliper placed between the two lugs, parallel to the caseback. It is one of the most common widths among large-format dive watches, ensuring broad compatibility with both OEM and aftermarket straps.

The ideal choice depends on intended use. For everyday wear and water resistance, a NATO nylon or vulcanised rubber strap in 22mm is the most coherent option given the watch's technical vocation. For a smarter profile, an alligator strap in navy blue or a waterproof smooth-grain calf strap enhances the sporty aesthetic without compromising it. Casati Milano crafts bespoke straps for this reference with short lead times and an 18-month guarantee.

To replace the strap, you need to remove the two 22mm spring bars connecting the strap to the case lugs. Use a thin-blade screwdriver (0.8–1mm) or a spring bar tool: insert the tip into the hole on the side of the lug, compress the spring bar and slide the strap free. The operation takes approximately two minutes per side and requires no professional tools, though working on a soft surface is advisable to protect the crystal and case.

Yes. Any strap with a 22mm attachment and standard length (75mm short half, 120mm long half) is compatible with the Breitling Superocean A1739010B772. Milano Straps and Casati Milano offer handcrafted straps in leather, alligator, shell cordovan, NATO and rubber, all designed to fit the 22mm lugs of this reference without adapters or case modifications.

Longevity depends on material, care and exposure to perspiration and moisture. A quality waterproof-treated calf strap typically lasts 18–24 months with daily use. An alligator or shell cordovan strap, properly maintained with protective cream and kept away from regular water exposure, can last 3–4 years or more. Casati Milano guarantees its straps for 18 months against manufacturing defects and provides specific care instructions based on the leather chosen.
