Strap for Premier Automatic 40 Stainless Steel / Anthracite / Bracelet

The lug width of the Breitling Premier A37340351B1A1 is 20mm. This measurement must be taken internally between the lug tips using a millimetre calliper, and is the essential reference for selecting a compatible strap.

For the Breitling Premier A37340351B1A1, the most suitable materials are belly-cut alligator for a dress register, vegetable-tanned calfskin for everyday wear, and shell cordovan for those seeking a distinctive texture. All three complement the brushed stainless steel 40mm case without overwhelming the Premier's silhouette.

The strap on the Breitling Premier A37340351B1A1 is changed by releasing the spring bars from the lugs using a dedicated spring bar tool. Place the watch face-down on a soft cloth to avoid scratching the case, and operate the tool carefully. Once removed, insert the spring bars into the new 20mm strap and press them into the lug holes until they lock in place.

Yes, the 20mm lug width of the Breitling Premier A37340351B1A1 is a widely supported standard in the aftermarket. Milanostraps.it offers a curated selection of handcrafted 20mm straps in various materials, available either as bespoke commissions through the Casati Milano atelier or as ready-to-ship options online.

The lifespan of a leather strap depends on the material and frequency of use. A well-maintained vegetable-tanned calfskin strap typically lasts 2–4 years; alligator or shell cordovan straps, owing to their denser fibre structure, can exceed 5 years with proper care. Milanostraps.it backs its straps with an 18-month manufacturing defect guarantee.
