Strap for Premier Chronograph 42 Stainless Steel / Black / Bracelet

The lug width of the Breitling Premier A1331535B1A1 is 20mm. This measurement is taken with a digital calliper at the internal distance between the two lugs at the point where they meet the case. 20mm is one of the most common lug widths in fine watchmaking, ensuring broad compatibility with aftermarket straps.

For the Breitling Premier A1331535B1A1, an alligator strap with vegetable tanning is the most coherent pairing given the model's formal-sport character. Shell cordovan is a refined alternative offering a dense, lustrous surface that complements the polished case finishing. For casual or summer wear, a technical rubber strap in 20mm preserves dimensional accuracy while offering comfort and moisture resistance.

To replace the strap on the Breitling Premier A1331535B1A1, use a fine-tipped spring bar tool. Insert the tip into the lateral slot of the lug to compress the spring bars and slide the strap free. Rest the case on a soft cloth to avoid scratching the case finishing. Refit the new strap in reverse order, ensuring the spring bars engage fully on both sides before wearing.

Yes, the Breitling Premier A1331535B1A1 uses standard 20mm lugs, for which a wide range of quality aftermarket straps is available. Milanostraps.it offers handcrafted straps in alligator, calf leather, shell cordovan and rubber, all dimensioned to 20mm with a straight end suited to the Premier's lug geometry. Standard length 115/75mm fits most wrists.

The lifespan of a leather strap depends on tanning quality and daily use. A high-grade vegetable-tanned alligator strap, rotated regularly and kept away from water, will maintain its structural and aesthetic integrity for 3 to 5 years. Shell cordovan, owing to its fibre density, tends to last even longer, developing a distinguished patina over time. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
