Breitling
Superocean A1739102BA80131S— lug 20mm

The lug width of the Breitling Superocean A1739102BA80131S is 20mm. This is the standard measurement required when selecting any compatible aftermarket strap. It should be measured between the lugs using a digital calliper, taking the internal distance at the strap attachment point.

It depends on intended use. For maintaining the watch's sporting and marine character, a vulcanised rubber strap in 20mm is the most coherent choice. For smart-casual or formal wear, a vegetable-tanned calf leather or Mississippiensis alligator strap with a brushed steel deployant clasp elevates the Superocean without compromising its technical identity.

The original bracelet is secured via standard 20mm spring bars. To remove it, use a fine-tipped spring bar tool: insert it between the lug and the bracelet, compress the spring bar, and slide it out laterally. The operation takes approximately two minutes per side. It is advisable to work on a soft surface to avoid scratching the case.

Yes. Any strap with a 20mm attachment width is technically compatible with the Breitling Superocean A1739102BA80131S, provided the spring bars are in stainless steel and the strap thickness at the lug end suits the case geometry. Milano Straps offers a comprehensive selection of 20mm straps in various materials and finishes, available to purchase directly online.

Longevity depends on leather type, care, and exposure to perspiration and moisture. A good quality calf leather strap typically lasts between 18 and 36 months with daily wear. Alligator, owing to its dense fibre structure, can exceed 3 to 4 years. Shell cordovan offers the highest resistance to surface wear. Leather straps are not recommended for water activities; rubber or NATO straps are preferable for aquatic use.
