Within a very small volume, a large number of components contribute to handling all the functions. Your Breitling chronometer is a sophisticated instrument that is constantly subjected to a wide variety of stresses and strains. In relation to the watch dial, the point located midway between the current time and 12 o’clock indicates North, South is exactly opposite. Point the hour-marker located at 12 o’clock on the dial precisely towards the sun. In relation to the watch dial, the point located midway between the current time and12 o’clock indicates South, North being exactly opposite. Point the hour hand precisely towards the sun. For regions that have instated daylight saving time, subtract one hour when aligning the watch. Your Breitling chronometer may be used as a sun compass, thus enabling you to determine North and South. You will thereby contribute to environmental and public health protection. We recommend returning them to your point of sale. Used batteries and used watch components should not be disposed of like regular garbage, but be correctly recycled. The battery must be replaced within the next few days by an authorized BREITLING agent.Īlso ask for a water-resistance test to be performed on the watch. The watch movement is fitted with a battery end-of-life detector (EOL), signaled by the small second’s hand beginning to jump every 4 seconds. It also provides the user with an instantaneous return direction reading, opposite to the heading followed in the outward flight. This function enables the pilot to “memorize” the heading to follow, by positioning it opposite the index at 12 o’clock. This bezel, indicating the cardinal points and headings, performs several navigation functions. Read the number of beats per minute on the pulsometer scale.

Start the chronograph, count 30 heartbeats, and then stop. Push the crown back into exit reset mode. Press push-button A to select the next hand.įollow the same procedure for the 3 hands. Press push-button B to move the hand to the correct position – 12 o’clock precisely.

Press push-button A to select the hand to reset – the selected hand will complete a full revolution. The chronograph hands may need to be reset if they are not in the 12 o’clock position at rest. The chronograph is reset to zero by pressing pushpiece B, once the ﬁnal measurement has been stopped.This procedure makes it possible to add up several short times. To restart the time measurement, press pushpiece A. To interrupt the measurement, press pushpiece A once more.Press pushpiece A to start the chronograph.Reset the chronograph to zero by pressing pushpiece B.The measurement is made in hours (totalizer 1), minutes (hand ), seconds (hand 3), and 1 /10 this of a second (totalizer 4). Stop the measurement by pressing pushpiece A once more.Hand 3 keeps track of the measured time in seconds. A chronograph is not necessarily chronometer-certified, but all Breitling chronographs carry the much-coveted title of “chronometer”. The term “chronometer” should not be confused with that of “chronograph”, which is a complicated watch fitted with an additional mechanism used for measuring the duration of an event. The variation in rate of the SuperQuartz™ calibre fitted in your Breitling watch far and above exceeds these demands, achieving a level of ☑5 seconds per year. To earn the prestigious chronometer label, a movement’s performances must meet 6 very strict criteria, including a daily variation in rate of within ☐.07 seconds, corresponding to an annual precision of ☒5 seconds. The certiﬁ cation test for wristwatch chronographs with quartz oscillators consists in observing each movement for 13 days and 13 nights, in several positions and at 3 diﬀ erent temperatures (8☌, 23☌, 38☌).
