Strap for Super Chronomat B01 44 Titanium / Grey / Rubber Rouleaux

The Breitling Super Chronomat EB0136251M1S1 has a lug width of 20mm. This measurement is taken internally between the two lugs of the case and determines compatibility with any aftermarket or replacement strap.

For the Super Chronomat in titanium and ceramic, the most suitable materials are vegetable-tanned alligator — which develops a distinctive patina over time — shell cordovan for a more refined and structured aesthetic, and vulcanised rubber for sporting use. All straps must feature a 20mm attachment width.

The strap is replaced by removing the spring bars from the lugs using a pointed spring bar tool. The Super Chronomat's lugs have a robust profile: a tool with a protected tip is recommended to avoid scratching the titanium surface. The operation takes only a few minutes and does not require professional watchmaking assistance.

Yes, any strap with a 20mm attachment is technically compatible. For the best result, straps with a slightly curved end or calibrated padding are preferable, as they follow the profile of the titanium lugs more accurately. Milano Straps offers a selection of handcrafted 20mm straps compatible with this reference.

The lifespan of a leather strap depends on the material, care routine, and frequency of use. A quality vegetable-tanned alligator strap, maintained regularly with leather conditioner, typically lasts 3–5 years of daily wear. Shell cordovan, due to its dense and compact fibre structure, tends to retain its shape longer. Prolonged exposure to water and perspiration significantly reduces the strap's service life.
