Strap for Premier Automatic 40 Stainless Steel / Blue / Bracelet

The Breitling Premier A37340351C1A1 features a lug width of 20mm, measured internally between the two case horns. This is one of the most common measurements in fine watchmaking, ensuring broad availability of quality aftermarket straps. For an accurate replacement, it is advisable to verify the measurement with a digital calliper before purchasing.

Given the elegant character of the Premier A37340351C1A1, a vegetable-tanned alligator strap with belly grain is the most coherent choice with the watch's identity. Alternatively, smooth calf leather or shell cordovan offer character and longevity for daily wear. For more dynamic settings, a quality rubber strap maintains aesthetic consistency with the 40mm stainless steel case.

To replace the strap on the Breitling Premier A37340351C1A1, use a lever-type spring bar tool or a flathead screwdriver with a 1.0–1.2mm tip to remove the spring bars housed within the lugs. Work on a soft surface to avoid scratching the case and verify that the spring bars are correctly tensioned before refitting. If in doubt, Casati Milano's atelier offers a professional strap fitting service.

Yes, the Breitling Premier A37340351C1A1 accepts any aftermarket strap measuring 20mm, with standard or curved ends to match the internal profile of the lugs. Milanostraps.it offers a curated selection of handcrafted leather, rubber and textile straps specifically sized for this width, with finishes and colours chosen to complement the Premier's aesthetic. Closure options include a traditional buckle or a stainless steel deployant clasp.

The lifespan of a leather strap depends on the quality of the tanning, the leather thickness and conditions of use. A top-quality alligator or calf leather strap with vegetable tanning and artisanal finishing has an average life of 2–4 years with regular wear. Prolonged exposure to water, perspiration and perfume will significantly reduce longevity. Casati Milano provides an 18-month guarantee against manufacturing defects on all bespoke straps.
