BreitlingNavitimer

The Navitimer is the 1952 pilot's chronograph with a circular slide rule in its bezel, made for the Aircraft Owners and Pilots Association. This library holds 492 references, and the Breitling B01 is inside 194 of them.

About the Breitling Navitimer

The slide rule was carried over from the 1942 Chronomat and turned toward aviation: fuel consumption, climb rates, distance and unit conversions, all worked from the rotating bezel against the fixed inner scale. The first reference, the 806, used the Venus 178; the 1962 Cosmonaute added a 24-hour dial for Scott Carpenter's orbital flight; and the 1969 ref 1806 carried the Chrono-Matic, one of the first automatic chronograph movements. The 2022 redesign flattened the case and the slide rule and returned the AOPA wings to the dial.

Movements divide the collection into eras. The Valjoux 7750-based Caliber 13 and the Caliber 17 with its no-date variant carried the 1990s and 2000s Navitimers, 141 references between them. Since 2009 the in-house B01 column-wheel chronograph has been the standard, with the B03 rattrapante in 39 references, the hand-wound B02 in the Cosmonaute, and the B04 GMT. The Breitling reference number encodes which one is fitted, a rule covered in the reference guide, so an AB01 prefix is a B01 before the watch is opened.

Sizes run from 32 mm to 48 mm. The 43 mm and 41 mm cases are the most common at 131 and 121 references, and the 46 mm at 88. Steel is the material for 343 of them, red gold for 87. Black dials lead at 151, blue at 107, and 106 references are limited editions. Water resistance is 30 m throughout, which is a pilot's watch rating, not a diver's.

The AVI revives the pre-Navitimer ref 765, and the Chronomat is the other B01 chronograph line.
