Strap for Super Chronomat 38 Stainless Steel / Ice Blue / Rouleaux

The lug width of the Breitling Super Chronomat A17356531C1A1 is 20mm. This measurement is taken internally between the two lugs using a digital calliper positioned parallel to the case. The 20mm lug width is a widely standardised size, ensuring broad compatibility with quality aftermarket straps.

The ideal choice depends on the intended use. For formal or business settings, a Hornback alligator strap with vegetable tanning in black or midnight blue complements the ceramic and steel contrast of the case. For intensive daily or sporting use, grained calf leather or vulcanised rubber are more appropriate. A ballistic nylon NATO strap aligns naturally with the Chronomat family's aviation heritage.

The strap is removed using a flat-tip or forked spring bar tool, applying gentle pressure on the spring bar housed within the lug. To avoid scratching the black ceramic case material, place a thin strip of protective tape over the lugs before starting. The swap takes approximately two minutes and requires no specialist tools.

Yes. The standard 20mm lug width of the Super Chronomat A17356531C1A1 is compatible with a wide range of aftermarket straps. Milano Straps offers handcrafted straps in alligator, calf leather, shell cordovan, and rubber, all fitted with a straight 20mm end. Ensure the strap end is straight rather than tapered for a proper fit against the lugs.

A quality leather strap — vegetable-tanned alligator or selected calf — typically lasts between two and five years with daily wear, depending on exposure to perspiration, water, and UV light. Regular conditioning with an unscented leather cream significantly extends its lifespan. Straps produced by Casati Milano carry an 18-month warranty against manufacturing defects.
