Strap for Super Chronomat B01 44 Stainless Steel / White / Japan

The Breitling Super Chronomat AB0136A71A1S1 has a lug width of 20mm. This measurement is taken with a digital calliper between the two lugs at the strap attachment point. It is Breitling's standard lug width for this reference and allows compatibility with any 20mm aftermarket strap.

For the Super Chronomat with its black ceramic bezel, a vegetable-tanned alligator strap in dark tones — tobacco, midnight blue or dark brown — creates a refined contrast between natural texture and matte ceramic. For sporting use, a vulcanised rubber strap or ballistic nylon NATO are the most coherent choices for this watch's intended purpose.

As this model features an integrated bracelet, strap replacement requires a springbar tool or, in some cases, a dedicated screw-type fitting. It is advisable to have the strap changed by a watchmaker or at the Casati Milano atelier to avoid scratching the ceramic lugs. The replacement strap must have a 20mm attachment width, ideally with curved ends to match the lug profile.

Yes. Milanostraps.it offers a curated selection of 20mm straps compatible with the Super Chronomat AB0136A71A1S1, available in alligator leather, calfskin, shell cordovan, nylon NATO and rubber. Casati Milano bespoke straps are handcrafted to order, with stitching and buckle options chosen by the client.

A quality leather strap with vegetable tanning and proper finishing has an average lifespan of 2–4 years with daily wear, depending on perspiration, moisture exposure and maintenance. Alligator and shell cordovan straps, due to the density of their fibre, tend to outlast standard calfskin. Casati Milano provides an 18-month guarantee against manufacturing defects.
