The Superocean A3238011BA38140S, seen from the bench

The Breitling Superocean A3238011BA38140S is a professional dive watch with a 41 mm stainless steel case and 20 mm lug width, part of the Superocean family originating from Breitling's Grenchen laboratories in the 1950s. It features a unidirectional bezel, screw-down crown, and the Breitling Caliber 32 automatic movement, offering hours, minutes, seconds, date, and a 24-hour hand for dual time zone reading. The 41 mm steel case with mixed satin and polished finishing pairs with various aftermarket strap materials including vegetable-tanned leather and exotic skins, though the lug geometry requires pre-curved or flexible strap ends for proper fitment.

Frequently asked questions

What is the lug width of the Breitling Superocean A3238011BA38140S?

The Breitling Superocean A3238011BA38140S has a lug width of 20 mm. This measurement is taken between the two lugs at the strap attachment point using a digital calliper. It is the standard size compatible with the majority of quality 20 mm aftermarket straps.

What is the best strap for the Breitling Superocean A3238011BA38140S?

The choice depends on intended use. For a formal register, alligator leather or shell cordovan offer superior patina and structure. For daily and marine use, a ballistic nylon NATO strap or vulcanised rubber strap provide durability and comfort. In all cases, a strap with pre-curved ends is recommended to fit the Superocean's lug profile correctly.

How do you change the strap on the Breitling Superocean A3238011BA38140S?

Strap replacement requires a springbar tool or a thin spatula-style tool. Compress the 20 mm springbar between the lugs, slide out the original strap, and insert the new one. Work on a soft surface to avoid scratching the stainless steel case. Alternatively, Casati Milano offers professional fitting in their Milan atelier by appointment.

Are there aftermarket straps compatible with the Breitling Superocean A3238011BA38140S?

Yes. Any standard 20 mm springbar strap is technically compatible. Milanostraps.it offers a curated selection of handcrafted 20 mm straps in various materials and finishes, all made with stitching and keepers calibrated for a precise fit on the Superocean's lugs.

How long does a leather strap last on a Breitling Superocean?

Longevity depends on the material and usage. A vegetable-tanned alligator strap with regular use and proper care typically lasts 2–4 years. Shell cordovan, being denser and more compact, tends to last longer. Prolonged exposure to salt water and excessive perspiration should be avoided. Casati Milano provides an 18-month guarantee against manufacturing defects on all their straps.
