Strap for Premier B01 Chronograph 42 Stainless Steel / Black / Bracelet

The lug width of the Breitling Premier AB0145221B1A1 is 22mm. This measurement is taken internally between the two case lugs and is the sole determining factor for strap compatibility.

For the Premier AB0145221B1A1, a vegetable-tanned Tuscan calf or a belly alligator strap with symmetrical scales is the most coherent choice given the model's dressy character. The natural grain of the leather complements both silver and blue dials, developing a personal patina over time.

To replace the strap on the Premier AB0145221B1A1, use a fine-tipped spring bar tool. Compress the internal spring of each spring bar to release the strap from the lugs without scratching the case. It is advisable to work on a soft surface and ensure the new spring bar diameter is compatible with the lug holes (typically 1.5mm).

Yes. Any strap with a 22mm lug attachment and a standard 20mm tail is technically compatible with the Premier AB0145221B1A1. Milano Straps offers handcrafted straps in calf leather, alligator, shell cordovan and technical materials, available bespoke or ready-to-ship for 22mm lug width.

The lifespan of a leather strap depends on the material and frequency of wear. A quality vegetable-tanned calf strap, with regular conditioning every 2–3 months, typically lasts 2–4 years before the fold area shows structural fatigue. Alligator and shell cordovan, owing to their denser fibre structure, can exceed 5 years with proper care.
