Breitling
Superocean A17366021B1S2— lug 20mm

The lug width of the Breitling Superocean A17366021B1S2 is 20mm, measured between the inner lug walls with a digital calliper. The measurement is consistent between the inner and outer lug width, which simplifies strap selection.

The ideal choice depends on context. For aquatic or sportive use, vulcanised rubber is the most technically appropriate option. For everyday wear with a degree of formality, an alligator or vegetable-tanned calfskin strap fitted with a brushed steel deployant clasp complements the instrument's character without contradiction.

Strap replacement requires a fine-tipped spring bar tool or a dedicated watch screwdriver. Compress the spring bar inside the lug and slide the strap free. No professional equipment is required, though working on a soft surface is strongly recommended to avoid scratching the case.

Yes. Any strap with a 20mm attachment width is geometrically compatible. Milanostraps.it offers a curated selection of handcrafted straps in 20mm width, made from selected leathers and materials specifically suited to diving watches such as the Superocean.

Under normal conditions without water immersion, a quality vegetable-tanned calfskin strap typically lasts between two and four years. Alligator leather, owing to its denser fibre structure, can exceed five years with regular maintenance. Prolonged exposure to salt water or chlorine accelerates deterioration significantly; a rubber strap is recommended for aquatic use.
