FAQ

What is the lug width of the Breitling Premier A13315351B1P1?

The lug width of the Breitling Premier A13315351B1P1 is 20mm. This measurement is taken with a calliper between the lugs at the narrowest insertion point of the strap, and determines compatibility with any aftermarket watch strap.

What is the best strap for the Breitling Premier A13315351B1P1?

For the Breitling Premier A13315351B1P1, a polished alligator strap is the most coherent choice, given the collection's elegant character. Alternatively, vegetable-tanned calf leather or shell cordovan offer durability and a progressive patina. For sporting use, a shaped rubber strap in 20mm is the most practical option.

How do you change the strap on a Breitling Premier A13315351B1P1?

The strap on the Breitling Premier A13315351B1P1 is replaced by removing the two spring bars that secure it to the lugs. A dedicated spring bar tool or fork-tip screwdriver is required. The procedure is straightforward but should be performed carefully to avoid scratching the stainless steel case. A watchmaker or the Casati Milano atelier can carry this out complimentary with any strap purchase.

Are there aftermarket straps compatible with the Breitling Premier A13315351B1P1?

Yes, any strap with a standard 20mm attachment and spring bars is compatible with the Breitling Premier A13315351B1P1. Milano Straps offers a curated selection of handcrafted 20mm straps in various materials and finishes, proportioned to suit the Premier case without any modification.

How long does a leather strap last on a Breitling Premier A13315351B1P1?

The lifespan of a leather strap depends on the material and frequency of use. A quality vegetable-tanned calf strap typically lasts 2–4 years with daily wear. Shell cordovan can exceed 5 years due to its dense fibre structure. Alligator, when properly maintained, offers comparable longevity. Milano Straps straps carry an 18-month warranty against manufacturing defects.
