Strap for Super Chronomat B01 44 Stainless Steel / Green / Rubber Rouleaux

The lug width of the Breitling Super Chronomat AB0136251L1S1 is 20mm. This measurement is essential when selecting a compatible strap to ensure a precise fit without play or pressure on the lugs.

For the 44mm Super Chronomat in ceramic and stainless steel, alligator straps with hornback or nile grain offer the best balance between elegance and substance. Alternatively, a vegetable-tanned calf leather strap or a technical nylon NATO complement the sporting DNA of the B01 calibre.

Strap replacement requires a spring bar tool to remove the spring bars from the 20mm lugs. It is advisable to work on a soft surface to protect the ceramic case, which is particularly susceptible to impact scratches. If in doubt, consult a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 20mm attachment is technically compatible with the Super Chronomat AB0136251L1S1. Milano Straps offers a curated selection of handcrafted 20mm straps — in leather, alligator, NATO and rubber — designed to fit the original Breitling lugs precisely.

A quality leather strap with vegetable tanning and careful finishing typically lasts 2–4 years with daily wear. Longevity depends on exposure to perspiration, moisture and UV light. Casati Milano straps carry an 18-month warranty against manufacturing defects and can be treated with specific conditioners to extend their lifespan.
