Introduction

This manual provides instructions for the proper use and care of your Breitling Navitimer 1 Chronograph 41 watch, model A1332412-BG74-743P. This timepiece features a Swiss Automatic movement, chronograph functions, and a slide rule bezel. Please read these instructions carefully to ensure optimal performance and longevity of your watch.

Setup

1. Unboxing and Initial Inspection

Upon receiving your Breitling Navitimer 1 Chronograph 41, carefully remove it from its packaging. Inspect the watch for any visible damage or irregularities. Ensure all protective films are removed from the crystal and case back.

2. Winding the Watch

Your Navitimer 1 Chronograph 41 is equipped with a self-winding automatic movement. Before wearing for the first time or after a period of inactivity, manually wind the watch by rotating the crown clockwise approximately 30-40 times while it is in the closed position (position 0). This builds up the power reserve. The watch will then continue to wind itself through the motion of your wrist while worn.

3. Setting the Time and Date

1. Unscrew the crown: If your watch has a screw-down crown, gently unscrew it counter-clockwise until it springs out to position 0.
2. Set the date (Position 1): Pull the crown out to the first click (Position 1). Rotate the crown clockwise or counter-clockwise to set the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
3. Set the time (Position 2): Pull the crown out to the second click (Position 2). The seconds hand will stop. Rotate the crown to set the hour and minute hands. To ensure accurate time setting, align the minute hand precisely with a minute marker when the seconds hand reaches 12 o'clock.
4. Push and screw down the crown: Once the time and date are set, push the crown back into position 0. If it is a screw-down crown, gently screw it back in clockwise until it is firmly secured against the case. This ensures water resistance.

Operating the Chronograph and Slide Rule

1. Chronograph Functions

The chronograph allows for precise measurement of elapsed time. It is operated using the two pushers located on either side of the crown.

• Start: Press the upper pusher (A) to start the chronograph. The large central seconds hand will begin to move.
• Stop: Press the upper pusher (A) again to stop the chronograph. The elapsed time can be read from the central seconds hand, the minute counter (typically at 3 o'clock), and the hour counter (typically at 6 o'clock).
• Reset: After stopping the chronograph, press the lower pusher (B) to reset all chronograph hands to their zero positions. Do not press the reset pusher while the chronograph is running.

2. Slide Rule Bezel (Navitimer Specific)

The bidirectional rotating bezel of your Navitimer features a circular slide rule, a tool for performing various calculations. This function requires practice to master.

The slide rule consists of two logarithmic scales: a fixed scale on the dial (inner scale) and a rotating scale on the bezel (outer scale).

• Multiplication: To multiply A by B, align the "10" (or "UNIT") mark on the outer scale with the number A on the inner scale. Then, read the result on the inner scale opposite the number B on the outer scale.
• Division: To divide A by B, align the number A on the inner scale with the number B on the outer scale. Then, read the result on the inner scale opposite the "10" (or "UNIT") mark on the outer scale.
• Unit Conversion: The slide rule can also be used for various unit conversions (e.g., miles to kilometers, gallons to liters) by aligning known conversion factors.

Note: Mastering the slide rule requires understanding logarithmic scales and practice. Refer to specialized aviation slide rule guides for detailed instructions on complex calculations.

Maintenance and Care

1. Cleaning

To clean your watch, use a soft, damp cloth. For stainless steel parts, a mild soap solution can be used, followed by rinsing with clean water and drying thoroughly. Ensure the crown is fully screwed down before any contact with water. Avoid using harsh chemicals or abrasive materials.

2. Water Resistance

Your watch has a water resistance rating of 30 meters (3 ATM). This means it is suitable for splashes or brief immersion in water, but not for swimming, showering, or diving. Always ensure the crown is fully screwed down to maintain water resistance. Water resistance is not a permanent characteristic and may decrease over time due to aging gaskets or accidental impacts. It is recommended to have the water resistance checked periodically by an authorized service center.

3. Leather Strap Care

The leather strap is susceptible to wear and tear from moisture, sweat, cosmetics, and prolonged exposure to sunlight. To prolong its life, avoid prolonged contact with water and direct sunlight. Clean with a dry, soft cloth. Replace the strap if it shows signs of significant wear or damage.

4. Service Intervals

For optimal performance and longevity, it is recommended to have your Breitling watch serviced by an authorized service center every 3-5 years. Regular servicing includes cleaning, lubrication, and replacement of worn components, as well as checking water resistance.

5. Magnetic Fields

Avoid exposing your watch to strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices), as this can affect the accuracy of the mechanical movement.

Troubleshooting

• Watch not running or stopping frequently:

  Solution: Ensure the watch is sufficiently wound. Manually wind the watch by rotating the crown 30-40 times clockwise. If the issue persists, the watch may require servicing.

• Time inaccuracy:

  Solution: Check if the watch has been exposed to strong magnetic fields. If so, demagnetization by a professional may be necessary. Ensure the watch is fully wound. If inaccuracy continues, professional adjustment or servicing is recommended.

• Chronograph hands not resetting to zero:

  Solution: Ensure the chronograph is stopped before pressing the reset pusher. If the hands still do not align, a professional adjustment is required.

• Date not changing correctly:

  Solution: Verify that the time is set correctly for AM/PM. The date typically changes around midnight. Avoid setting the date manually between 9 PM and 3 AM. If the issue persists, seek professional assistance.
