Strap for Premier Automatic Day & Date 40 Stainless Steel / Silver / Bracelet

The lug width of the Breitling Premier A45340211G1A1 is 20 mm. This measurement is taken between the inner edges of the lugs where the spring bars sit. Before purchasing an aftermarket strap, it is advisable to verify this dimension with a digital calliper, as minor production tolerances may occasionally occur.

Given the dressy-sport character of the Premier A45340211G1A1, a padded alligator strap with a wide grain pattern or a vegetable-tanned calf leather strap that develops a natural patina over time are the most coherent choices. For casual or active wear, a technical nylon NATO or a vulcanised rubber strap offer functional alternatives that respect the instrument-grade nature of the calibre.

Strap replacement requires a spring bar tool. Insert the forked tip into the small notch at the side of the lug, compress the spring bar and slide the strap free. The operation is non-invasive and fully reversible. Work on a soft surface to avoid scratching the stainless steel case, and always replace spring bars with ones rated for a 20 mm lug width.

Yes. Any standard 20 mm strap is compatible with the Premier A45340211G1A1. Milano Straps offers a curated range of handcrafted 20 mm straps in various leathers and finishes. For a fully bespoke result, Casati Milano atelier produces made-to-measure straps with personally selected hides and hardware, including a deployant clasp option in polished or brushed steel.

Longevity depends on material quality and daily use. A vegetable-tanned calf leather strap typically lasts 18 to 36 months with regular wear. A top-grade alligator strap, owing to the dense fibrous structure of the hide, can exceed 3 to 5 years while developing a distinctive patina. Prolonged exposure to perspiration, water and UV light accelerates deterioration; rotating between straps and storing them away from heat sources is strongly recommended.
