FAQ
What is the lug width of the Breitling Super Chronomat AB0136251B1S1?
The Breitling Super Chronomat AB0136251B1S1 features a lug width of 20mm. This measurement can be confirmed using a digital calliper placed between the two inner lug terminals, flush against the caseback side of the dial. Any compatible strap must have a 20mm attachment width.
What is the best strap for the Breitling Super Chronomat AB0136251B1S1?
Given the black ceramic and stainless steel case construction, the most effective strap choices are: alligator in tobacco or slate grey for a formal register, vegetable-tanned grain calf for everyday wear with a developing patina, FKM rubber for active or marine use, and ballistic nylon NATO for the original aviator aesthetic. A brushed steel deployant clasp on leather significantly improves daily wrist comfort.
How do you change the strap on a Breitling Super Chronomat AB0136251B1S1?
The strap is removed using a fine-tipped spring bar tool or a small flathead screwdriver, applying gentle lever pressure to the spring bar connecting the strap to the lug. It is advisable to work on a soft surface to protect the ceramic bezel and dial from accidental scratching. A watchmaker or specialist atelier can perform the swap in a matter of minutes.
Are there aftermarket straps compatible with the Breitling Super Chronomat AB0136251B1S1?
Yes. Any strap with a 20mm attachment width and a terminal profile compatible with the Super Chronomat's curved lugs can be fitted to this reference. Milanostraps.it offers a curated selection of handcrafted 20mm straps made in Italy from selected leathers. For a fully bespoke solution — including choice of material, grain, stitching and clasp — the Casati Milano atelier service is available by appointment.
How long does a leather strap last on a Breitling Super Chronomat?
Strap longevity depends on leather quality, hide thickness, exposure to perspiration and water, and frequency of use. A high-quality alligator or vegetable-tanned calf strap, worn on rotation and properly maintained, can last between two and five years while retaining structural integrity and aesthetic quality. Casati Milano straps carry an 18-month warranty against manufacturing defects.
