The Caliber B19 Arrives: Breitling’s Most Advanced Navitimer Yet

Breitling introduces two new perpetual-calendar chronographs that represent the Navitimer at its highest expression. The Navitimer B19 duo is inspired by the extreme altitudes the iconic pilot’s chronograph has mastered.

For over 70 years, the Navitimer has taken on many roles, from essential pilots’ tool to cultural icon. This year, Navitimer Stories will bring these chapters to light across aviation, lifestyle, and technical savoir faire, showing why this remarkable timepiece remains as relevant today as ever. Created in 1952 for the Aircraft Owners and Pilots Association (AOPA), the Navitimer united a chronograph with Breitling’s patented circular slide rule, allowing aviators to perform flight calculations directly from their wrist. The quintessential pilots’ watch, it soon proved itself across every altitude—worn by supersonic pilots at the edge of space and by astronauts from the earliest days of human spaceflight.

Now presented in its highest expression of complexity and materials, Breitling introduces the Navitimer B19 as two exceptional timepieces powered by the brand’s manufacture B19 perpetual-calendar chronograph movement. Rendered in steel and platinum or full platinum and finished in altitude inspired colorways, they celebrate the vertical journey of Breitling’s icon.

“At Breitling, we have always pushed limits, not only through our iconic designs, but also by engineering exceptional movements that power our watches.” says Georges Kern, CEO of Breitling. “The Navitimer B19 delivers on both sides.”

A CENTURY IN MOTION: THE CALIBER B19

At the heart of this high-altitude duo is the Breitling Manufacture Caliber B19, first introduced in 2024 to mark the brand’s 140th anniversary. It represents a major technical milestone,combining Breitling’s chronograph exper tise with a true perpetual calendar, one that automatically accounts for leap years and varying month lengths, and will not require a major manual correction for a century. The moonphase adds a final celestial link, reinforcing the Navitimer’s original purpose as an instrument made for the sky.

Technically, the Navitimer B19 has set a new benchmark for Breitling, a feat that earned it a 2025 Temporis Award. It is an automatic perpetual calendar chronograph with a 96-hour power reserve. A one-step correction system via the crown allows all calendar indications to be advanced together, while two discreet dimple-style pushers at 8 and 10 o’clock enable individual adjustments. Winding is handled by a solid 18k red-gold rotor, visible through the sapphire caseback, and the movement is COSC-certified as a chronometer for unwavering precision.

It is, quite simply, the most advanced movement ever housed in a Navitimer and currently the only core-catalog automatic perpetual-calendar chronograph on the market.

 

ALTITUDE AS COLOR, MATERIAL, AND MOOD

The timepieces translate the Navitimer’s story in the air universe into two powerful, tangible expressions. Each model channels a different altitude. A 75-piece limited edition in full platinum features a deep blue lacquered dial inspired by the stratosphere at high cruising altitudes, where the atmosphere thins, the sky deepens, and the Earth’s curvature becomes visible. The full platinum case is paired with a black outer slide rule and a contrasting white inner scale, drawing the eye toward the dial’s celestial center. It is fitted
with a matching navy-blue alligator strap with a folding clasp.

The second execution, in stainless steel with a platinum bezel, is defined by its anthracite dial, reflecting the stillness and depth of space. It features the same high-contrast slide rule configuration and refined dial architecture and is delivered on a brown alligator strap or seven-row steel bracelet, underscoring its dramatic, cosmic tone.

Both models share a series of refined design signatures. Their dials provide depth and sheen, while raised metal rings around the subdials introduce a new three-dimensional architecture.

The moonphase disc at 12 o’clock draws the eye with its detail, and each case is finished with Breitling’s signature knurled bezel. Each dial becomes a miniature universe: technical, celestial, and instantly recognizable as a Navitimer.

AN ICON, STILL IN FLIGHT

The Navitimer was born from professional demand. With its signature slide rule, it became an essential cockpit tool during the golden age of civil aviation. Over time, its distinctive look moved beyond the flight deck, appearing on the wrists of figures as varied as Miles Davis, Serge Gainsbourg, and Formula 1 legends Graham Hill and Jim Clark, and even into space with astronaut Scott Carpenter, while remaining faithful to its original form.

With this pair of exceptional watches, Breitling unites heritage, high complication, and modern design in a way only the Navitimer can. They are shaped by civil aviation, inspired by the skies above, and engineered to measure time for generations.

Frederique Constant Classics Moneta Moonphase

In August 2024 Frederique Constant unveiled its Classics Moneta Moonphase, a timepiece on which the traditional fluted bezel motif was moved to the flange, giving the case the appearance of a coin – hence the ‘Moneta’ moniker. Now the Geneva-based manufacture has added further style flourishes, giving two of the original models with blue or silver dials a new look that takes them into a whole other aesthetic dimension.

For the first variation, Frederique Constant has opted for a PVD case done out in yellow gold with matching hands and hour markers – a classic prestige livery. For the first time ever, the second timepiece features a Milanese mesh bracelet, beautifully offsetting the steel colour of the case, externals and Moon display at six o’clock and resulting in a more vintage look. Both watches retain the 37-millimetre diameter case and are powered by a quartz movement that makes the Classics Moneta Moonphase that bit more affordable – and desirable.

One of Frederique Constant’s most foundational style principles is timelessness, characterised by a vintage look coupled with discreet modernity – and both new variations of the Classics Moneta Moonphase take the expression of that principle to new heights. Are they vintage, contemporary, urban, Sixties, or Seventies? At the end of the day the answer is very much in the eye of the beholder; the one thing that’s not up for debate is the thoroughly horological nature of the two timepieces.

In the best traditions of fine watchmaking, the dials sport a meticulous sunray finish, softly diffusing light towards the twelve applique hour markers above which hand-polished dauphine hands glide effortlessly. The decision not to include a seconds hand blurs the boundary between quartz and mechanical movements: at first glance, it’s impossible to tell which powers the Classics Moneta Moonphase. The calm, peaceful atmosphere exuded by the dial is further highlighted by the moonphase at six o’clock. Earth’s closest neighbour cycles through its phases in 27 days, 7 hours, 43 minutes and 12 seconds at a rate invisible to the naked eye. Housed in a 37-millimetre case, the restrained and elegant Classics Moneta Moonphase embodies the canons of watchmaking etiquette, be it on men’s or ladies’ wrists.

The style signature of the Classics Moneta Moonphase is its flange, crafted to resemble the edge of a coin. Here, this hallmark of Geneva watchmaking has been moved from its original location on the bezel, instead adding grooved relief to the dial. Frederique Constant’s creativity delights in these clever, sophisticated new takes on convention – giving the brand its very own design ethos in the process.

On the first new variation, the brilliant yellow gold colour adds a further sense of prestige to the piece; the finish is a first for a Classics Moneta Moonphase. The Moon, stars and all the externals (the case, hour markers, hands, and crown) are done out in the same hue, underscoring the philosophy of affordable luxury so dear to Frederique Constant.

The second version offers a steel colour scheme to complement its gold counterpart. Instead of a calfskin strap, the watch sports a Milanese mesh bracelet – another first in the Classics Moneta Moonphase collection. The flexible bracelet fits snugly around the wrist almost like a second skin, giving the piece both a daringly relaxed air and a vintage look; Milanese mesh was all the rage in the 1970s. The steel bracelet beautifully offsets the colour of the applique hour markers and dauphine hands (another icon of vintage watches), as well as the lunar grey of the Moon and stars. The complication is encircled by a thin gold line matching the lettering of the brand’s ‘Frederique Constant, Genève’ signature at twelve o’clock.
