FAQ

What is the lug width of the Breitling Super Chronomat AB01364A1I1S1?

The lug width of the Breitling Super Chronomat AB01364A1I1S1 is 20mm. This measurement is taken internally between the two lugs of the case and is the key parameter for selecting a compatible aftermarket strap. It is advisable to confirm this with a digital calliper before purchasing.

What is the best strap for the Breitling Super Chronomat AB01364A1I1S1?

The ideal choice depends on the intended use. For formal occasions, a 20mm glossy alligator or shell cordovan strap in burgundy is the most refined option. For sport or casual wear, a vegetable-tanned calf leather with grain texture or a black vulcanised rubber strap offers comfort and durability. A brushed steel deployant clasp is strongly recommended to complement the visual weight of the 44mm case.

How do you change the strap on a Breitling Super Chronomat AB01364A1I1S1?

The Super Chronomat AB01364A1I1S1 uses standard 20mm spring bars for strap attachment. To replace the strap, use a dedicated spring bar tool or a thin flat-head screwdriver to release the bars. Work on a soft surface to protect the ceramic bezel and case finishing. If in doubt, consult a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling Super Chronomat AB01364A1I1S1?

Yes. Any strap with a standard 20mm lug width and spring bar fitting is technically compatible with the Super Chronomat AB01364A1I1S1. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps specifically proposed for this lug size, with materials and finishes chosen to complement the ceramic and steel case construction.

How long does a leather strap last on a Breitling Super Chronomat AB01364A1I1S1?

Longevity depends on the material and conditions of use. A quality alligator strap, kept away from prolonged exposure to water and perspiration, can last between three and five years while developing a distinguished patina. Vegetable-tanned calf leather develops character over time but is more susceptible to wear from frequent moisture exposure. For intensive sport use, a rubber strap is recommended as it is unaffected by weather conditions. Casati Milano provides an 18-month warranty against manufacturing defects on all straps.
