FAQ

What is the lug width of the Breitling Super Chronomat AB01367A1B1S1?

The lug width of the Breitling Super Chronomat AB01367A1B1S1 is 20mm. This measurement is taken between the inner faces of the lugs at the point where the strap meets the case, and should be verified with a calliper for accuracy.

What is the best strap for the Breitling Super Chronomat AB01367A1B1S1?

Given the ceramic and stainless steel case, the most suitable options are a lisse alligator strap for formal wear, shell cordovan for those seeking a noble patina over time, or a vulcanised rubber strap for daily sport use. In all cases, the correct width is 20mm, ideally with curved ends to follow the case profile.

How do I change the strap on the Breitling Super Chronomat AB01367A1B1S1?

Use a fine-tipped spring bar tool to release the spring bars housed within the lugs. Work on a soft surface to protect the ceramic bezel and case from accidental scratches. The original Breitling spring bars are standard diameter and compatible with most 20mm aftermarket straps.

Are there aftermarket straps compatible with the Breitling Super Chronomat AB01367A1B1S1?

Yes. Any 20mm strap with standard or curved ends is compatible with the Super Chronomat AB01367A1B1S1. Milano Straps offers a curated range of handcrafted straps in various leathers and finishes, all available in the correct lug width. It is advisable to check the end curvature to ensure a flush fit against the case.

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

Strap longevity depends on the leather type, frequency of use, and exposure to perspiration and moisture. A quality vegetable-tanned calfskin strap typically lasts 2–3 years with regular wear. Shell cordovan, owing to its dense fibre structure, can exceed 4–5 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
