The Breitling Premier B21 Chronograph Tourbillon 42 (JB2120A61B1P1) is a striking fusion of high watchmaking and refined aesthetics. Encased in luxurious 18k white gold, the 42mm case houses the exceptional Breitling B21 caliber, a self-winding mechanical movement developed in partnership with Manufacture La Joux-Perret. This movement features a 1/4th second chronograph, a 60-minute counter, and a power reserve of approximately 55 hours, operating at a high frequency of 28,800 vibrations per hour with 30 jewels for smooth performance. A cambered sapphire crystal—glareproofed on both sides—enhances clarity, while the screwed-in sapphire caseback offers a view of the intricate inner workings.

Built for both elegance and durability, the watch features a fixed bezel, a non screw-locked crown with double gaskets, and water resistance up to 10 bars (100 meters). With a thickness of 15.25 mm and a lug-to-lug height of 50.03 mm, the case balances bold presence with comfort. The black alligator leather strap is curved to fit the wrist and secured with a folding clasp in matching 18k white gold. Weighing approximately 155 g, this timepiece is a true symbol of sophistication and precision—perfect for collectors and connoisseurs who appreciate fine mechanical craftsmanship and timeless design.
