Strap for Superocean Heritage II 42 Stainless Steel / Blue / Blue / Croco / Pin

The lug width of the Breitling Superocean Heritage AB201016/C960/731P/A20BA.1 is 22mm. This measurement refers to the internal distance between the case lugs at the point where the strap attaches, and must correspond precisely to the head width of the chosen strap.

For the Superocean Heritage 42mm, the most appropriate options are technical rubber for diving or intensive sport use, vegetable-tanned Tuscan calf leather for daily wear with natural patina development over time, and Mississippi alligator for formal occasions. A navy/red two-tone NATO strap is a classic choice that reinforces the watch's maritime heritage.

Strap replacement requires a fine-tipped springbar tool or lever-style lug tool. The lugs on the Superocean Heritage 42mm accept standard 22mm spring bars. Insert the tool tip into the spring bar slot, compress the spring, and slide the strap outward. The operation does not require opening the case and has no effect on the watch's water resistance.

Yes. Any strap with a head width of 22mm and a tail width of 20mm or 18mm (depending on the buckle selected) is technically compatible. Milano Straps artisan straps are manufactured to precise tolerances to ensure correct fitment within the lugs without forcing. The recommended standard length is 75/115mm or 75/120mm depending on wrist circumference.

On a dive watch such as the Superocean Heritage, the longevity of a leather strap depends heavily on actual water exposure. For daily dry or occasionally damp use, a quality vegetable-tanned calf strap typically lasts 2–4 years while retaining its aesthetic and structural integrity. Prolonged contact with salt water or chlorine accelerates degradation of the leather fibre structure. For regular water use, rubber is recommended; for mixed use, the leather strap should be removed before immersion.
