The Heritage

The Breitling Superocean A1736402BA28428X is a 42mm stainless steel dive watch certified to 1000 metres, belonging to a lineage dating back to 1957. It features an ETA 2824-2 automatic movement modified to COSC chronometer standards, with a 38-hour power reserve and a unidirectional bezel for maximum readability underwater. The 22mm lug width accepts standard 22mm straps without adapters, featuring straight-profile lugs with 1.5mm pins.

FAQ

What is the lug width of the Breitling Superocean A1736402BA28428X?

The Breitling Superocean A1736402BA28428X features a 22mm lug width, measured between the two case lugs in stainless steel. This is a standard dimension compatible with any 22mm strap without the need for adapters. To verify the measurement on your own piece, a digital calliper placed between the lugs will provide the most accurate reading.

What is the best strap for the Breitling Superocean A1736402BA28428X?

The ideal choice depends on context. For aquatic or sporting use, vulcanised rubber or ballistic nylon NATO straps are most consistent with the Superocean's technical vocation. For a dress-sport setting, alligator or vegetable-tanned calf leather with a stainless steel deployant clasp offers a more refined look without undermining the watch's character. Shell cordovan suits those seeking compactness and long-term patina development.

How do you change the strap on the Breitling Superocean A1736402BA28428X?

The original strap is secured by standard spring bars with a 1.5mm diameter. Replacement requires a spring bar tool or a watchmaker's flat-tip tool: compress the spring bar, slide out the old strap and insert the new one. No watchmaker intervention is required; the operation takes under two minutes with the correct equipment.

Are there aftermarket straps compatible with the Breitling Superocean A1736402BA28428X?

Yes. Any strap with a standard 22mm attachment is fully compatible with the Breitling Superocean A1736402BA28428X. Milano Straps offers an extensive range of handcrafted 22mm straps in leather, alligator, NATO and rubber, made from carefully selected materials and available in various lengths and tapers. Bespoke options are available through the Casati Milano atelier.

How long does a leather strap last on a Breitling Superocean A1736402BA28428X?

Longevity depends primarily on leather quality, tanning method and usage conditions. A vegetable-tanned calf or shell cordovan strap, with proper care, can last three to five years with daily wear. Prolonged exposure to salt water or perspiration accelerates deterioration: for aquatic use, rubber or NATO straps are recommended, reserving leather for dry contexts. Milano Straps provides an 18-month warranty against manufacturing defects.
