Strap for Premier Automatic Day & Date 40 Stainless Steel / Silver / Croco Brown / Folding

The lug width of the Breitling Premier A45340211G1P1 is 20 mm. This measurement should be taken with a calliper placed between the inner edges of the lugs, flush against the case, excluding the bezel. Any strap listed as 20 mm at the attachment end will be compatible.

For the Premier A45340211G1P1, a vegetable-tanned alligator strap is the most coherent choice given the model's sartorial character: the symmetrical grain complements the brushed steel case finishes. Alternatively, smooth calfskin or shell cordovan develops a natural patina over time. For casual settings, a two-tone nylon NATO strap is both functional and aesthetically appropriate.

To replace the strap on the Premier A45340211G1P1, use a fine-tipped springbar tool. Compress the spring mechanism inside the lug, extract the bar and remove the strap. The operation takes approximately two minutes and requires no specialist skills, though it is advisable to work on a soft surface to avoid scratching the case.

Yes, any strap with a 20 mm attachment width is compatible with the Premier A45340211G1P1. Milano Straps offers a selection of handcrafted straps in various leathers and materials, available bespoke or ready to ship, with standard buckle or deployant clasp. Ensure the springbars have the correct diameter for Breitling lugs, typically 1.5 mm.

The lifespan of a leather strap depends on the quality of the tanning, frequency of wear, and care. A high-quality vegetable-tanned alligator strap worn regularly but not in extreme conditions will last between three and five years whilst retaining its shape. Cordovan and fine calfskin offer similar longevity. Avoid prolonged contact with water and perspiration, and apply a neutral leather conditioner periodically.
