Strap for Superocean Heritage B01 Chronograph 42 Stainless Steel - Red Gold / Black / Rubber

The lug width of the Breitling Superocean Heritage UB0156H11B1S1 is 22mm. This measurement refers to the internal distance between the two lugs at the point where the strap attaches to the case. For an accurate reading on your specific piece, use a digital calliper placed directly between the lugs.

Given the combination of ceramic, red gold and stainless steel, the most suitable options are alligator porosus straps in cognac or tobacco brown — which complement the warmth of the red gold — or vegetable-tanned calf leather for a progressive, elegant patina. For sporting use, vulcanised rubber or ballistic nylon NATO straps are functionally consistent with the model's diving heritage.

To replace the strap, you will need a fine-tipped spring bar tool or a dedicated flat lever. The 22mm spring bar must be compressed laterally to release it from the lug hole. Work on a soft surface to protect the ceramic case and red gold components from accidental scratches. If you are not experienced with this procedure, it is advisable to consult a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 22mm attachment and standard spring bars is technically compatible. Milano Straps offers a selection of handcrafted 22mm straps — in leather, alligator, NATO and rubber — made with a straight edge for a precise fit in the Superocean Heritage lugs. Each strap comes with an 18-month guarantee against manufacturing defects.

Longevity depends on the materials and conditions of use. A vegetable-tanned calf leather strap, maintained regularly with natural conditioning creams and rotated with other straps, can last between three and six years while developing a distinguished patina. Alligator straps, owing to the dense fibre structure of the skin, generally outlast calf leather. Regular exposure to salt water or perspiration accelerates deterioration: in aquatic contexts, a rubber or NATO strap is the more appropriate choice.
