Strap for Superocean Heritage '57 Stainless Steel / Blue Rainbow / Calf / Folding

The lug width of the Breitling Superocean Heritage '57 A103702A1C1X2 is 20mm. This measurement refers to the internal distance between the case lugs and determines the correct strap size. To verify it accurately, use a digital calliper positioned at the narrowest section between the two lugs.

The ideal strap depends on intended use and aesthetic preference. For a refined look, an alligator strap in black or bordeaux with contrast stitching complements the turquoise dial beautifully. For a heritage aesthetic, vegetable-tanned calfskin in tobacco or navy is the most coherent choice. For aquatic use, vulcanised rubber offers maximum functionality. A nylon NATO strap remains the most historically faithful option for this sporting tool watch.

To change the strap on the Breitling Superocean Heritage '57, you will need a spring bar tool or lug pin remover to disengage the spring bars securing the strap to the lugs. Press the spring bar tips inward to release them from the lug holes. Always work on a soft surface to prevent scratching the case, and use dedicated watchmaking tools to avoid damaging the lugs.

The lifespan of a leather strap depends on hide quality, frequency of use, and exposure to perspiration and moisture. A high-quality vegetable-tanned calfskin strap, with daily wear and proper care, typically lasts between 2 and 4 years. Alligator leather, owing to its dense scale structure, generally offers greater longevity. Casati Milano provides an 18-month guarantee against manufacturing defects on all handcrafted straps.
