FAQ

What is the lug width of the Breitling Superocean A17365C9.BD67.132S?

The lug width of the Breitling Superocean Heritage 42 reference A17365C9.BD67.132S is 20mm. This is a standard measurement in professional diving watches, best verified with a digital calliper by measuring the inner distance between the two lugs at the point closest to the case.

What is the best strap for the Breitling Superocean Heritage 42?

It depends on intended use. For water activities, vulcanised rubber is unrivalled: waterproof and salt-resistant. For everyday urban wear, box-grain calf leather or ballistic nylon NATO straps offer versatility and durability. For formal occasions, a 20mm vegetable-tanned alligator strap completely redefines the character of the watch while preserving its structure.

How do I change the strap on the Breitling Superocean Heritage 42?

Strap replacement requires a spring bar tool to remove the two spring bars securing the strap to the lugs. Work on a soft surface to protect the case. The process takes approximately two minutes and requires no professional equipment, though care must be taken to avoid scratching the steel lugs.

Are there aftermarket straps compatible with the Breitling Superocean A17365C9.BD67.132S?

Yes. Any strap with a 20mm attachment is technically compatible with the Breitling Superocean Heritage 42. Milano Straps offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan, rubber and NATO, all fitted with quality spring bars and available in 20/18mm or 20/16mm taper widths.

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

A quality leather strap on a diving watch such as the Superocean will typically last 12 to 24 months with daily wear, provided it is kept away from water and excessive perspiration. Shell cordovan and vegetable-tanned alligator are the most durable options: they develop a characteristic patina over time and resist deformation. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
