Question 1

What is the Breitling Navitimer B01 Chronograph 43?

Question 2

What is the Navitimer and its slide rule for?

Accepted Answer

The Breitling Navitimer is one of the world's most iconic pilot's watches . Conceived in 1952, it was originally developed for the Aircraft Owners and Pilots Association (AOPA) and quickly became an essential tool for professional aviators. Its distinctive circular slide rule bezel sets it apart from other chronographs and has become one of the collection's defining design features. The slide rule is a mechanical calculating instrument that allows pilots to perform a variety of flight-related calculations directly on the wrist, including: Fuel consumption and fuel burn calculations Average speed and flight time calculations Distance and rate conversions Unit conversions (such as nautical miles, statute miles, and kilometers) Basic multiplication and division While modern aircraft now rely on advanced onboard computers, the slide rule remains a functional tribute to the Navitimer's aviation heritage and a hallmark of Breitling's history of precision instrument making. Today, it continues to distinguish the Navitimer as both a highly recognizable luxury chronograph and a symbol of aviation excellence.

Question 3

What does the chronograph function do?

Accepted Answer

A chronograph is a stopwatch built into the watch : pushers start, stop and reset the timing while the watch keeps the time on its main hands. To learn more about how Breitling chronographs work and the technology behind them, visit the Made by Breitling page .

Question 4

How do you use the chronograph on the Navitimer B01 Chronograph 43?

Accepted Answer

The Navitimer B01 Chronograph 43 uses a standard two-pusher column-wheel chronograph: Start / Stop : Press the top pusher (at 2 o'clock) to start the chronograph; press again to stop it. Reset : Press the bottom pusher (at 4 o'clock) reset the chronograph—this can only be done when the chronograph is stopped. Reading elapsed time : The central seconds hand shows elapsed seconds. The subdial at 3 o'clock counts up to 30 minutes. The sub-dial at 6 o'clock counts up to 12 hours. The running seconds sub-dial sits at 9 o'clock. The 12-hour counter is a defining feature of the Navitimer—absent from most sport chronographs—enabling timing across overnight or long-haul flights. Precision is one eighth of a second.

Question 5

What sizes does the Navitimer B01 Chronograph come in, and how does the 43 mm wear?

Accepted Answer

The Navitimer B01 Chronograph is available in three case sizes: 41 mm, 43 mm, and 46 mm —each housing the Manufacture Caliber 01. The 43 mm (ref. AB0138211B1P1) is the mid-size option, at 13.69 mm thick with a 22 mm lug width. At approximately 98 g total weight (77.2 g for the watch head), it has a substantial but balanced presence on the wrist. The 43 mm is widely considered the most versatile size in the Navitimer line : larger than the 41 mm for greater dial legibility with the slide rule markings, yet more refined than the 46 mm for everyday and dressed-up wear. The cambered sapphire crystal —glareproofed on both sides—creates a domed profile that references the original and adds perceived depth to the signature dial design.
