Strap for Super Chronomat B01 44 Watches of Switzerland Australia

The Breitling Super Chronomat AB01365A1Q1S1 has a lug width of 20mm. This measurement is taken between the two lugs on the caseback, at the point where the springbar is inserted. Despite the 44mm case diameter, Breitling opted for this width to maintain visual proportionality with the tapered profile of the integrated lugs.

The ideal choice depends on intended use and personal style. For a sport-elegant context, vegetable-tanned calfskin or mississippiensis alligator are the most appropriate options. For outdoor or marine use, vulcanised rubber is preferable for its resistance and water impermeability. It is essential to select straps with pre-curved ends that are compatible with the curved lug geometry of the Super Chronomat.

Strap replacement requires a springbar tool to remove the spring bars holding the strap to the lugs. The Super Chronomat's lugs have a curved profile, so care must be taken to avoid scratching the ceramic case. Alternatively, the operation can be carried out by a watchmaker or at the Casati Milano Atelier by appointment.

Yes. Aftermarket 20mm straps with curved or pre-formed ends are compatible with the Super Chronomat AB01365A1Q1S1, provided the end radius matches the Breitling lug profile. Milanostraps.it offers a curated selection of handcrafted 20mm straps, available bespoke or ready to ship.

The lifespan of a leather strap depends on the quality of the hide, the tanning process, and daily use. A quality calfskin or alligator strap with vegetable tanning, if properly maintained — kept away from prolonged water exposure and excessive perspiration — can last between 2 and 5 years with regular wear. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
