Strap for Top Time B01 Gino Bartali / Mesh

The Breitling Top Time AB01767A1C1A1 has a lug width of 20mm. This measurement refers to the internal distance between the lugs of the case — the width the strap must have at its top end to be correctly fitted using standard spring bars.

The ideal choice depends on context. For a vintage-racing aesthetic consistent with the Top Time's heritage, a cognac grain calf leather strap or a beige cotton NATO is strongly recommended. For more formal occasions, a black vegetable-tanned alligator strap complements the brushed steel case. Shell cordovan remains the premium option for those seeking durability and natural patina development over time.

To replace the strap, you will need a spring bar tool or a flat-tipped screwdriver to disengage the spring bars housed within the lugs. Remove the existing strap, insert the new 20mm strap, and refit the spring bars until they click securely into place. The process takes approximately two minutes and can be carried out independently with the correct tools, or entrusted to a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 20mm lug width is compatible with the Breitling Top Time AB01767A1C1A1, provided the spring bars have the correct diameter for Breitling lugs. Milanostraps.it offers a curated selection of handcrafted 20mm straps in premium materials, available online or bespoke through the Casati Milano atelier.

The lifespan of a leather strap depends on material quality, frequency of use, and exposure to perspiration and environmental factors. A high-quality alligator or shell cordovan strap, with moderate daily wear, will retain its structural integrity and aesthetic for 3 to 5 years. Vegetable-tanned straps develop a natural patina over time. It is advisable to avoid water immersion and to apply a neutral leather conditioner periodically.
