Key Components:
- Crown: Used for winding the watch and setting the time.
- Chronograph Pushers: Buttons located at 2 o'clock and 4 o'clock positions for operating the chronograph function.
- Main Dial: Displays hours, minutes, and seconds. Features a tachymeter scale on the outer rim.
- Sub-dials: Typically include a small seconds hand, a 30-minute counter, and a 12-hour counter for the chronograph.
- Sapphire Crystal: Scratch-resistant glass protecting the dial.
- Leather Strap: High-quality brown leather with a deployment clasp for secure fastening.
2. Setup and Initial Operation
2.1. Initial Winding
Although your Breitling Premier B09 is an automatic watch, it is recommended to manually wind it before initial use or if it has stopped due to lack of wear.
- Ensure the crown is in its fully pushed-in position (Position 0).
- Turn the crown clockwise approximately 30-40 times. This will build up a sufficient power reserve to start the movement.
2.2. Setting the Time
- Pull the crown out to Position 2 (the outermost position). The small seconds hand will stop, allowing for precise time setting.
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the desired time.
- Once the time is set, push the crown back into Position 0. The small seconds hand will resume movement.
3. Operating the Chronograph Function
The chronograph allows you to measure elapsed time independently of the main time display.
- Starting the Chronograph: Press the upper pusher (at 2 o'clock) once. The large central chronograph seconds hand will begin to move, along with the minute and hour counter sub-dials.
- Stopping the Chronograph: Press the upper pusher (at 2 o'clock) again. The chronograph hands will stop, indicating the elapsed time.
- Reading Elapsed Time:
- The central large hand indicates elapsed seconds.
- The sub-dial at 3 o'clock typically indicates elapsed minutes (up to 30 minutes).
- The sub-dial at 9 o'clock typically indicates elapsed hours (up to 12 hours).
- Resetting the Chronograph: After stopping the chronograph, press the lower pusher (at 4 o'clock) once. All chronograph hands will instantly return to their zero positions.
- Flyback Function (if applicable): This model may feature a flyback chronograph. If so, while the chronograph is running, pressing the lower pusher will instantly reset the chronograph and restart it from zero without needing to stop it first.
4. Maintenance and Care
Proper care will ensure the longevity and performance of your Breitling timepiece.
- Water Resistance: Your watch is water resistant to 100 meters (330 feet). This means it is suitable for showering, swimming, and snorkeling. Do not operate the crown or pushers when the watch is wet or submerged. Avoid exposing the leather strap to prolonged water immersion, as this can damage the material.
- Cleaning: Clean the case and metal bracelet (if applicable) regularly with a soft, damp cloth. For leather straps, wipe gently with a dry, soft cloth. Avoid using harsh chemicals or abrasive materials.
- Temperature Extremes: Avoid exposing your watch to sudden temperature changes or extreme temperatures (below 0°C / 32°F or above 50°C / 122°F), as this can affect the movement's accuracy and seals.
- Magnetic Fields: Keep your watch away from strong magnetic fields (e.g., speakers, refrigerators, MRI machines), which can magnetize the movement and affect accuracy.
- Shocks: While robust, avoid severe impacts or drops, which can damage the internal components.
- Service: It is recommended to have your watch serviced by an authorized Breitling service center every 3-5 years to ensure optimal performance and water resistance.
