The Superocean A1736402BA29131A, seen from the bench

The Breitling Superocean A1736402BA29131A continues a lineage rooted in 1957 as a professional diving instrument. This 42mm stainless steel example features the Breitling 17 automatic movement, derived from the ETA 2824-2 and regulated to Swiss manufacturing standards. The watch displays hours, minutes, seconds, and date on a highly legible dial with luminescent indices and unidirectional bezel. The 20mm lug width is native to this model's geometry and determines strap compatibility, ensuring proper fit and aesthetic balance. Stainless steel construction offers substantial presence without volumetric excess, with curved flanks for ergonomic comfort.

Frequently asked questions

What is the lug width of the Breitling Superocean A1736402BA29131A?

The lug width of the Breitling Superocean A1736402BA29131A is 20mm. This measurement should be taken with a digital calliper, placing the tips inside the lugs against the inner metal surfaces, to ensure an accurate reading before purchasing any aftermarket strap.

What is the best strap for the Breitling Superocean A1736402BA29131A?

For the stainless steel Superocean A1736402BA29131A at 42mm, vegetable-tanned calf leather is the most balanced choice for daily wear due to its resilience and the patina it develops over time. For sporting or marine use, vulcanised rubber or ballistic nylon NATO straps are recommended. For formal occasions, a square-scale alligator strap with a steel deployant clasp offers the highest level of elegance.

How do you change the strap on the Breitling Superocean A1736402BA29131A?

Changing the strap on the Superocean A1736402BA29131A requires a fine-tipped spring bar tool. Insert the tip into the springbar slot, compress the spring, and slide the strap free from the lug. Repeat on the opposite lug. To fit the new strap, reverse the process: insert the springbar on the fixed side first, then compress and hook it on the spring side. Always work on a soft mat to avoid scratching the case.

Are there aftermarket straps compatible with the Breitling Superocean A1736402BA29131A?

Yes. Any strap with a 20mm lug width is technically compatible with the Breitling Superocean A1736402BA29131A. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps specifically listed for 20mm lug widths, with finishes suited to the brushed and polished steel of the Breitling case.

How long does a leather strap last on the Breitling Superocean A1736402BA29131A?

The lifespan of a leather strap depends on tanning quality, exposure to perspiration and moisture, and maintenance. A quality vegetable-tanned calf strap, regularly conditioned and kept away from salt water, typically lasts between 2 and 4 years with daily wear. Alligator, owing to the density of its natural grain, tends to last longer but requires greater care regarding humidity.
