FAQ

What is the lug width of the Breitling Superocean A1736006.B909?

The Breitling Superocean A1736006.B909 has a lug width of 20mm. This measurement, taken between the two lugs on the caseback using a millimetre calliper, determines compatibility with any replacement strap. All 20mm straps available on milanostraps.it are compatible with this reference without adapters.

What is the best strap for the Breitling Superocean A1736006.B909?

For the 42mm satin-finished steel Superocean, the most suitable options are: vegetable-tanned alligator leather for formal or business-casual settings, shell cordovan for those seeking a progressive patina and compact grain, vulcanised rubber for water or high-humidity use, and ballistic nylon NATO for summer wear. The ideal choice depends on intended use and the desired chromatic pairing with the dial.

How do you change the strap on a Breitling Superocean A1736006.B909?

To replace the strap on the Superocean A1736006.B909, a springbar tool (fork-type screwdriver) must be inserted into the lug channel to compress the spring bars. Care is required to avoid scratching the satin case: it is advisable to protect the lugs with masking tape or to entrust the operation to a watchmaker or specialist atelier such as Casati Milano.

Are there aftermarket straps compatible with the Breitling Superocean A1736006.B909?

Yes. Any strap with a 20mm attachment width is compatible with the Breitling Superocean A1736006.B909. The aftermarket offers a wide selection in leather, rubber, nylon and metal. milanostraps.it offers handcrafted straps with tapered or straight ends, available with buckle or deployant clasp, in selected materials with hand-stitched finishing, all compatible with this reference.

How long does a leather strap last on a Breitling Superocean A1736006.B909?

The longevity of a leather strap depends on material quality, frequency of use, and exposure to perspiration and water. A high-quality alligator or shell cordovan strap, worn daily and kept away from saltwater, typically lasts between 2 and 4 years whilst retaining structural integrity and a dignified patina. Intensive sporting or diving use significantly reduces service life: in such cases, a vulcanised rubber strap is the more appropriate choice.
