Navitimer 1 Chronograph GMT Stainless Steel / Black / Calf / Folding

In Context

At 46 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 15.5 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

The movement winds itself from the motion of your wrist. 42 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

A24322121B2X2 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case. Beyond the time it carries a chronograph and a gmt.

Breitling's execution of the ETA/Valjoux 7754, the variant of the 7750 that adds an independently adjustable 24-hour hand for a second time zone. Actuation is cam-switched rather than column-wheel, the trade the 7750 family makes in favour of robustness and simpler servicing. It sits behind the travel-oriented models in the range, the Navitimer World and the Chronoliner, where the GMT hand rather than the chronograph is the point.

54 other watches in the library run the Breitling Caliber 24.
