Strap for Superocean Heritage II 46 Chronograph Stainless Steel / Black / Black / Calf / Pin

The lug width is 24mm. This dimension is specific to the 46mm model and is measured from inside to inside of the case at the lug attachment point. Verifying the compatibility of a new strap is essential: 24mm means the lug must fit perfectly into the case seats without play or excessive friction.

Vegetable-tanned alligator is the aristocratic choice, developing a rich patina over time. For those preferring versatility, nappa calf in neutral tones (black, cognac, navy blue) offers extraordinary comfort and simple maintenance. For authentic marine use, black FKM rubber guarantees saltwater resistance and extreme durability.

The Superocean Heritage uses a removable lug system with an internally threaded tube. To replace the strap: 1) position the watch on a protective pad, 2) gently unscrew the internal lug tube with a T-shaped screwdriver, 3) remove the old strap, 4) insert the new strap, 5) rethread the tube until the lug is perfectly taut with minimal movement. If preferred, entrust the operation to an authorised service centre.

No. Compatible means the strap has the correct lug width (24mm), but not all 24mm straps on the market will fit ideally. The best results are obtained with artisanal straps engineered to Breitling case specifications, such as those offered by Milano Straps, which guarantee precise tolerances and finishes consistent with the watch's technical character.

Strap longevity varies based on material and use. Vegetable-tanned alligator typically resists 3-5 years of moderate daily wear, with proper maintenance (quick drying, natural wax treatment every 6-12 months). Nappa calf requires greater attention to humidity but offers similar longevity. FKM rubber can last 5-7 years before showing structural fatigue.
