Strap for Premier Automatic 40 Stainless Steel / Anthracite / Croco Brown / Tang

The lug width of the Breitling Premier A37340351B1P2 is 20mm. This measurement should be taken with a digital calliper between the inner surfaces of the two lugs at the strap attachment point, ensuring a precise fit without visible gaps or misalignment.

For the Premier A37340351B1P2, a vegetable-tanned alligator belly strap is the most coherent choice given the watch's dress-oriented character. Shell cordovan is a strong alternative for those who prefer a denser grain and superior long-term durability. Both develop an authentic patina that complements the classical dial aesthetic.

To replace the strap on the Premier A37340351B1P2, use a fine-tipped spring bar tool. Insert the tool into the notch between the lugs and compress the spring bar laterally to release it. Remove the old strap, position the new one with the spring bars compressed, and release, ensuring both tips seat correctly within the lug holes.

Yes. Any strap with a 20mm attachment width is technically compatible with the Premier A37340351B1P2. Milano Straps offers a curated selection of handcrafted leather, alligator and other material straps — available for immediate purchase online or made to order — specifically suited to this lug width.

A quality leather strap — vegetable-tanned alligator or shell cordovan — on a watch like the Premier typically lasts between 3 and 5 years with daily wear, depending on exposure to perspiration, humidity and UV light. Vegetable-tanned leather develops a natural patina over time but benefits from occasional conditioning to maintain hydration and edge integrity.
