Breitling Navitimer B01 Chronograph 43 Ab0121211g1a1 Silver Watch

The Breitling Navitimer B01 Chronograph 43 AB0121211G1A1 presents the iconic pilot's chronograph in its most refined, wearable format — a 43mm stainless steel case paired with a silver dial and the legendary bidirectional slide rule bezel. Driven by Breitling's in-house Calibre B01, this reference strikes the ideal balance between heritage aesthetics and modern manufacture credentials.

Movement

Powered by the Breitling Calibre B01 — a COSC-certified chronometer movement developed and manufactured entirely in-house at Breitling's La Chaux-de-Fonds facility. Beating at 28,800 vph (4 Hz) with a 70-hour power reserve, the B01 features a column-wheel chronograph mechanism and vertical clutch for smooth, precise start/stop operation. The movement is visible through the sapphire exhibition caseback.

Dial

The silver dial lends this Navitimer a classic, understated elegance — complementing the polished and brushed steel case beautifully. The characteristic circular slide rule frames three symmetrically arranged sub-dials: a 30-minute chronograph counter at 3 o'clock, a 12-hour counter at 6 o'clock, and a running seconds display at 9 o'clock. Applied hour markers and luminous hands ensure legibility in all conditions.

Case & Bracelet

The 43mm stainless steel case offers a versatile, wrist-friendly size — substantial enough to command presence without overwhelming the wrist. This reference is presented on a stainless steel Navitimer bracelet with a folding clasp, integrating seamlessly with the case for a cohesive, sporty-elegant look.

Heritage & Collectability

In continuous production since 1952 and originally developed in partnership with the Aircraft Owners and Pilots Association (AOPA), the Navitimer is one of the most enduring and recognisable chronographs in horological history. The silver dial AB0121211G1A1 on bracelet is a particularly versatile and collectible reference — equally at home in a boardroom or cockpit. The in-house B01 calibre significantly enhances its long-term value proposition over earlier ETA-powered generations.
