Strap for Super Chronomat B01 44 Red Gold / Black MOP / Rouleaux

The lug width of the Breitling Super Chronomat RB01365A1B1R1 is 20mm. This measurement should be taken with a digital calliper between the two lugs, with the case lying flat on a surface, at the point of contact with the strap. This is the essential parameter for selecting a compatible aftermarket strap.

For the Super Chronomat in red gold with a mother-of-pearl dial, a polished alligator leather strap is the most coherent pairing with the watch's formal register. Alternatively, vegetable-tanned calf leather offers breathability and develops an authentic patina over time. Shell cordovan, with its grain-free surface, is a refined choice that complements the warmth of red gold naturally. For sport or summer use, vulcanised rubber provides water resistance and wearing comfort.

The strap on the Super Chronomat is removed using a flat-tip or fork-style spring bar tool, by releasing the spring bars connecting the strap to the case lugs. It is advisable to work on a soft surface to protect the red gold case and ceramic bezel from scratches. If replacing the original integrated Rouleaux bracelet, we recommend entrusting the operation to an authorised watchmaker. The replacement strap must have a 20mm lug width.

MilanoStraps offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan and rubber, available bespoke or in standard sizes.

The lifespan of a leather strap depends on the material, tanning quality and frequency of use. A quality vegetable-tanned calf strap typically lasts 1–2 years with daily wear. Alligator leather, thanks to its compact scale structure, tends to last longer when kept away from moisture and perspiration. Shell cordovan is the most durable of the classic leathers. MilanoStraps provides an 18-month guarantee on manufacturing defects for all its straps.
