Frequently asked questions

What is the lug width of the Breitling Premier A45340211G1X2?

The Breitling Premier A45340211G1X2 has a lug width of 20mm. This measurement should be taken with a digital calliper at the inner distance between the lugs, at the spring bar attachment point, to ensure a precise fit and correct visual alignment.

What is the best strap for the Breitling Premier A45340211G1X2?

For the Premier A45340211G1X2 in stainless steel, a vegetable-tanned alligator strap with a polished finish best complements the formal character of the dial. Box-grain calf leather is ideal for daily wear, whilst shell cordovan represents the most exclusive choice for those seeking a distinctive patina over time. In all cases, the correct lug width is 20mm.

How do you change the strap on a Breitling Premier A45340211G1X2?

To replace the strap on the Breitling Premier A45340211G1X2, use a dedicated springbar tool inserted into the lug hole to compress the spring bar and release the strap. Work on a soft surface to protect the stainless steel case from scratches. Fit the new strap in reverse order, ensuring both spring bars click securely into place.

Are there aftermarket straps compatible with the Breitling Premier A45340211G1X2?

Yes, the aftermarket offers a wide selection of straps compatible with the Breitling Premier A45340211G1X2, owing to its standard 20mm lug width. Milanostraps.it provides handcrafted straps in alligator, calf leather, shell cordovan and rubber made for this specific width, with customisable finishes and stitching available through the Casati Milano atelier.

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

The lifespan of a leather strap depends on the quality of the tanning, frequency of wear and maintenance. A high-grade vegetable-tanned alligator strap, rotated with other straps and kept away from excessive perspiration and moisture, will retain its structural and aesthetic integrity for 3 to 5 years. Shell cordovan, due to the density of its fibres, tends to last longer and develops a sought-after patina. Milanostraps.it offers an 18-month guarantee against manufacturing defects.
