FAQ

What is the lug width of the Breitling Super Chronomat AB0136251B1A1?

The lug width of the Breitling Super Chronomat AB0136251B1A1 is 20 mm. This measurement is taken between the two lugs on the inner side of the case, where the strap makes contact. It is one of the most common lug widths in high-end sports watchmaking, ensuring a wide availability of compatible straps.

What is the best strap for the Breitling Super Chronomat AB0136251B1A1?

For the Super Chronomat with a black ceramic bezel, the most suitable straps are in glossy-finished smooth alligator, vegetable-tanned calfskin with a tight grain, or shell cordovan for those seeking durability and a natural patina over time. A deployant clasp in steel is preferable to a pin buckle, as it distributes tension across the lugs more evenly and extends the strap's structural life.

How do you change the strap on the Breitling Super Chronomat AB0136251B1A1?

To replace the strap on the Super Chronomat AB0136251B1A1, use a spring bar tool inserted into the lug notch to compress the spring bars. Work on a soft surface to avoid scratching the case. If in doubt, the operation can be carried out by a watchmaker or at a specialist atelier by appointment.

Are there aftermarket straps compatible with the Breitling Super Chronomat AB0136251B1A1?

Yes. Any strap with a 20 mm attachment, straight or slightly curved ends, is compatible with the Super Chronomat AB0136251B1A1. Milano Straps offers a curated selection of artisanal leather and rubber straps in 20 mm, also available as bespoke pieces through the Casati Milano atelier.

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

The lifespan of a leather strap depends on the material and usage. A quality alligator strap with vegetable tanning can last between 3 and 7 years with regular wear. Shell cordovan tends to last longer due to its dense, compact fibre structure. Prolonged exposure to water, perspiration, and UV rays accelerates deterioration: leather straps should not be worn during aquatic activities.
