Breitling Navitimer B01 Chronograph 46

About This Watch

The Breitling Navitimer B01 Chronograph 46 is the largest expression of the iconic pilot's watch, designed for those who prefer maximum wrist presence and uncompromising dial legibility. At 46mm, this is a bold, commanding timepiece that harks back to the oversized pilot's watches of the mid-20th century. The larger case provides additional real estate for the intricate slide rule bezel scale, making it more legible and — for those who actually use it — more practical. The blue dial with silver-toned subdials creates a striking contrast that is especially effective on the larger canvas. Inside beats the same B01 manufacture chronograph caliber found across the Navitimer range, with its column wheel, vertical clutch, and 70-hour power reserve ensuring top-tier chronograph performance. The 46mm case is not for everyone — at 54mm lug-to-lug, it requires a wrist of at least 7.5 inches for comfortable wear. But for those with the wrist size to carry it, this is perhaps the most visually impactful Navitimer in the lineup. The oversized format makes a statement about the wearer's confidence and appreciation for bold, functional design rooted in aviation history.
