Strap for Super Chronomat B01 44 Stainless Steel / Shula 347 / Rubber

The Breitling Super Chronomat AB01368A1C1S1 features 20mm lug width. This measurement is taken with a digital calliper between the two inner lug tips, perpendicular to the axis of rotation. The lugs have a slight curvature to match the case profile, so curved or semi-curved strap ends are recommended for a clean, gap-free fit.

The most suitable options for the Super Chronomat AB01368A1C1S1 are: polished alligator leather for an elegant contrast with the ceramic case, vegetable-tanned calfskin for a sporting look that develops patina over time, NATO nylon to enhance the aeronautical heritage, and technical rubber for intensive daily use. A deployant clasp in steel complements the case geometry and reduces stress on the leather.

To replace the bracelet or strap on the Super Chronomat, remove the 20mm spring bars using a dedicated springbar tool. Given the slightly curved lug geometry, care must be taken to avoid scratching the ceramic or steel case surfaces. If in doubt, consult a professional watchmaker or the Casati Milano atelier for a safe, professional strap change.

Yes, a wide range of aftermarket straps with a 20mm lug width are compatible with the Super Chronomat AB01368A1C1S1. It is essential to ensure the strap ends are curved or semi-curved to match the case's lug geometry. Milano Straps offers a curated selection of handcrafted 20mm straps available online, or bespoke options through the Casati Milano atelier.

The lifespan of a leather strap depends on material quality, tanning method, and usage habits. A high-quality alligator or shell cordovan strap, properly maintained, can last between 3 and 7 years with regular wear. Vegetable-tanned calfskin develops a beautiful patina but requires protection from moisture. Rotating between multiple straps and avoiding prolonged water exposure will significantly extend their useful life.
