The Heritage

The Breitling Superocean 36 A17316D21A1A1 is a 36mm stainless steel dive watch featuring a unidirectional rotatable bezel, screw-down crown, and ISO 6425 certification for real diving. Powered by the automatic Breitling caliber 17 with central hours, minutes, seconds and date display at 3 o'clock, it combines professional diving capability with everyday wearability. The lug width is 18mm, matching the watch's proportionate case diameter and historical 1960s dive watch dimensions.

FAQ

What is the lug width of the Breitling Superocean 36 A17316D21A1A1?

The lug width of the Breitling Superocean 36 A17316D21A1A1 is 18mm. This measurement refers to the internal distance between the two lugs of the case and is the critical value when selecting a compatible strap. It is advisable to verify the measurement with a digital calliper before purchasing, to rule out any fitting discrepancies.

What is the best strap for the Breitling Superocean 36 A17316D21A1A1?

The ideal choice depends on intended use. For sport or diving contexts, a vulcanised rubber or technical nylon NATO strap is the most functional option, consistent with the watch's tool-watch heritage. For a more refined register, an 18mm alligator or vegetable-tanned calfskin strap in a matte finish complements the brushed steel case without undermining the Superocean 36's sporting character.

How do you change the strap on the Breitling Superocean 36?

The strap on the Breitling Superocean 36 is secured by standard 18mm springbars. To replace it, use a springbar tool: insert the tip into the notch on the lug, compress the spring pin and slide the strap free. The operation requires no specialist tools, but care should be taken to avoid scratching the brushed case surface. If in doubt, consult a watchmaker.

Are there aftermarket straps compatible with the Breitling Superocean 36 A17316D21A1A1?

Yes. Any strap with an 18mm lug width is geometrically compatible with the Breitling Superocean 36. Milanostraps.it offers a curated selection of handcrafted leather, NATO and rubber straps already filtered for this size. For a fully bespoke result, Casati Milano produces made-to-measure straps with personal selection of leather, colour and stitching directly in the atelier.

How long does a leather strap last on a Breitling Superocean 36?

The lifespan of a leather strap depends on the quality of the tanning, frequency of use and maintenance. A good-quality calfskin strap worn daily typically lasts between 12 and 24 months. Cordovan and alligator, owing to their denser fibre structure, offer considerably greater longevity. Avoiding prolonged contact with water and perspiration extends strap life significantly; periodic application of a leather conditioner preserves both the leather and the buckle hardware.
