Strap for Superocean Heritage '57 Stainless Steel / Red Gold / Black / Calf / Pin

The lug width of the Breitling Superocean Heritage '57 U10370121B1X1 is 20mm. This measurement is taken internally between the two lugs, perpendicular to the caseback axis. Always verify with a digital calliper before purchasing an aftermarket strap.

For the two-tone red gold and stainless steel case, vegetable-tanned alligator leather in cognac or bordeaux tones offers the most coherent formal pairing. Shell cordovan is a refined alternative for a tighter, smoother surface. For sporting or marine use, a vulcanised rubber strap with period-correct ribbed texture is the most appropriate choice.

The strap is removed using a flat-tip or fork-style spring bar tool, applying gentle leverage against the spring bar inside the lug. Protect the case with a soft cloth during the operation. No specialist tools are required, though for precious bimetal cases it is advisable to entrust the operation to a watchmaker for the first replacement.

Yes. Any strap with a 20mm lug width is compatible. It is also advisable to check the caseback profile to ensure a proper fit at the lug channel. milanostraps.it offers a curated selection of handcrafted 20mm straps compatible with this reference, in various materials and lengths.

Longevity depends on material quality, maintenance and frequency of use. A vegetable-tanned alligator strap, kept away from excessive moisture and conditioned periodically, will maintain its structural and aesthetic integrity for three to five years. Shell cordovan, owing to its dense fibrous structure, can exceed five years with routine care.
