The Premier AB01181A1Q1A1 (aka: AB01181A.Q627.452A), seen from the bench

The Breitling Premier AB01181A1Q1A1 is a 42 mm stainless steel chronograph launched to honor 1940s aesthetics, combining technical precision with formal dress-watch styling. Powered by the in-house Breitling B01 movement—an automatic mechanical chronograph with column wheel, COSC certification, 28,800 vph frequency, and approximately 70-hour power reserve—it features a blue lacquered dial, applied indices, and polished steel case with satin flanks. The 22 mm lug width suits the case diameter for balanced visual proportions. Material options include vegetable-tanned alligator leather with natural patina development, full-grain Tuscan calf for versatility, or dynamic alternatives.

Frequently asked questions

What is the lug width of the Breitling Premier AB01181A1Q1A1?

The lug width of the Breitling Premier AB01181A1Q1A1 is 22 mm. This measurement is taken internally between the two lugs of the case using a digital calliper and corresponds to the strap width at the point of attachment to the case.

What is the best strap for the Breitling Premier AB01181A1Q1A1?

For the Premier AB01181A1Q1A1, with its blue lacquer dial and 42 mm stainless steel case, a vegetable-tanned alligator strap is the most coherent choice given the watch's formal character.
