The Breitling Navitimer B03 Chronograph Rattrapante 45

It has been more than 85 years since Breitling introduced the first modern chronograph, whose influence on the watch design in general has been incalculable back then. With its new Navitimer B03 Chronograph Rattrapante 45, featuring its interpretation of one of watchmaking’s greatest complications, the brand has shown that it is still offering innovations.

The Navitimer B03 Chronograph Rattrapante 45 is as aesthetically impressive as it is technically sophisticated. Housed in a big, bold 45 mm red gold case, it is distinguished by a Stratos Gray dial and is water-resistant up to 3 bar. Its hour markers and hour and minute hands are coated with Super-LumiNova, which guarantees easy legibility in all lighting conditions. The chronograph has a bidirectional rotating bezel with the circular slide ruler that has long been associated with Breitling’s Navitimers.
Breitling has varied the stylized “B” logo with an anchor symbol for this watch and divided it between two hands. The “B” is on the red chronograph hand, while the anchor sits on the split-second hand. As a result, the two elements of the logo are separated when the split-second hand is stopped and reform when the hands realign with each other.

The split-second pusher, which is housed in the crown at 3 o’clock, serves to stop and restart the split-second hand as often as desired during a timing operation, allowing the wearer to measure split times or compare the results of several competitors.

Breitling has equipped the Navitimer B03 Chronograph Rattrapante 45 with an in-house movement, the calibre B03. It is a unique split-second movement. With its two superimposed central chronograph hands, it can measure two elapsed times simultaneously. The COSC-certified chronometer, whose performance can be viewed through the transparent sapphire caseback, offers a power reserve of around 70 hours. The automatic movement works at a frequency of 4 Hz.
