Breitling Navitimer Rattrapante

Breitling Navitimer Rattrapante

Launched in 1952, and introduced at Baselworld for 2017, the Navitimer has introduced one of the most demanding watchmaking complications: the split-seconds chronograph. Entirely developed and produced in the firm’s workshops, its Manufacture Breitling caliber B03 introduces two new patented innovations.

The first stems from the key challenge raised by the construction of such a chronograph: energy. Breitling has developed an innovative system serving to isolate the split-seconds hand so as to avoid its starting and stopping phases generating variable energy requirements liable to be detrimental to chronometric precision and reduce the power reserve.

The second patent relates to the mechanism for stopping the split-seconds hand. Inspired by cycle brakes, Breitling has wrapped the traditionally used wheel with an O-ring seal that compresses the clamp, thereby ensuring precise stopping and greater reliability.

In developing its self-winding split-seconds chronograph Caliber B03, Breitling worked on the basis of its Manufacture Breitling Caliber 01, which has already enabled the addition of other useful functions such as an easy to operate second time zone and world time displays.

The B03 therefore picks up all the advantages of this high-performance movement, including a 70-hour power reserve (guaranteeing enhanced rating regularity) as well as an innovative modular-type architecture. The split-seconds mechanism comprises just 28 parts.

Regrouping most of these components in a module fitted between the mainplate and the calendar mechanism not only simplifies production and assembly, but also maintenance – since the watchmaker can remove the module as a single block for any servicing or repairs.

Like all Breitling movements, the Manufacture Breitling Caliber B03 is chronometer-certified by the COSC (Swiss Official Chronometer Testing Institute), the only precision and reliability benchmark based on an international norm.

The Breitling Navitimer Rattrapante will be initially available in steel and in a limited edition of 250 pieces in 18ct red gold. Prices are $11,090 in steel and $32,895 in gold.
