Introducing Breitling AVI (ref. AB3521U41B1P2), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 43 mm in diameter, with a thickness of 14.35 mm, defined by a round silhouette, paired with a rotating, single mark bezel. The caseback is open, and the crystal is sapphire, delivering water resistance to 10000 meters. At a glance, the dial balances texture and clarity: a black tone with sunburst finish, framed by arabic numerals hour markers, and syringe hands. At its heart beats a proven engine: the Caliber B35 caliber. First released in 2018. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
