Strap for Superocean 42 Stainless Steel / Black / Bracelet / Japan

The lug width of the Breitling Superocean A17366D71B2A1 is 20mm. This measurement should be taken internally between the lugs using a millimetre calliper at the narrowest point, ensuring an accurate fit for any aftermarket strap.

It depends on the intended use. For diving or water sports, a vulcanised rubber strap is the most functional choice. For everyday elegant wear, vegetable-tanned calf leather or alligator develop a desirable patina over time. A ballistic nylon NATO strap suits those who appreciate the tool watch tradition.

Strap replacement requires a springbar tool or a dedicated lug lever. Insert the tip into the lug hole, compress the spring bar and slide the strap free. No professional tools are needed, though working on a soft surface is advisable to protect the case finish.

Yes. Any strap with a 20mm lug width is technically compatible. Milanostraps.it offers a curated selection of handcrafted leather, rubber and textile straps specifically suited to the Superocean, available with standard buckles or deployant clasps in various metal finishes.

The lifespan of a leather strap depends on exposure to moisture, perspiration and UV light. On an intensively used diving watch, expect a useful life of 12–24 months with regular conditioning. With mixed use and proper care, a quality handcrafted alligator strap can last 3–5 years while retaining structural integrity and patina.
