Strap for Super Chronomat B01 44 Stainless Steel - Red Gold / Green / Rouleaux

The lug width of the Breitling Super Chronomat UB0136251L1U1 is 20mm. This measurement refers to the internal distance between the two lugs where the strap inserts into the case. It is essential to use this figure — rather than the external lug width — when selecting a compatible replacement strap.

For a hybrid ceramic, rose gold and steel case, a Mississippiensis alligator strap in cognac or tobacco tones with a gloss finish offers the most coherent chromatic dialogue with the rose gold elements. Vegetable-tanned calf leather with natural grain provides an everyday option that develops a rich patina over time. For sporting use, vulcanised rubber or NATO webbing maintains aesthetic consistency with the Super Chronomat's technical vocabulary.

Strap replacement on the Super Chronomat requires the removal of the spring bars housed in the lugs. A fine-tipped springbar tool is recommended to avoid scratching the ceramic surface. While the operation can be performed independently with the correct tools, entrusting the task to a watchmaker or atelier specialist is advisable to protect the case integrity, particularly around the ceramic components.

Yes, any strap with a 20mm lug width is technically compatible with the Super Chronomat UB0136251L1U1. Milano Straps offers a curated selection of handcrafted 20mm straps in leather, rubber and nylon, available either as bespoke commissions or as ready-to-ship items online. Buckles and deployant clasps can be specified in steel or rose gold PVD to match the case aesthetic.

The longevity of a leather strap depends on the quality of the tanning process, leather thickness and daily care routine. A high-grade alligator or vegetable-tanned calf strap, rotated with at least one spare strap and worn daily, will typically maintain structural and aesthetic integrity for 2 to 4 years. Prolonged exposure to water and perspiration is the primary cause of premature wear; rubber or NATO straps are recommended for sports activities or summer use.
