Configuració
Enrotllant el rellotge
Your Breitling Navitimer is an automatic mechanical watch. It is powered by the motion of your wrist. If the watch has stopped or has not been worn for an extended period, it may need to be manually wound to initiate operation.
- Unscrew the crown (if it is a screw-down crown) by turning it counter-clockwise.
- In position 1 (crown pushed in), turn the crown clockwise approximately 40 times. This will fully wind the mainspring.
- Empenyeu la corona cap enrere i enrosqueu-la en sentit horari per garantir la resistència a l'aigua.
Configuració de l'hora i la data
- Unscrew the crown (if applicable) and pull it out to position 2 (first click). Turn 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.
- Pull the crown out to position 3 (second click). The seconds hand will stop. Turn the crown to set the hour and minute hands. To ensure precise time setting, synchronize the seconds hand with an official time signal.
- Once set, push the crown back in and screw it down (if applicable) to secure water resistance.
Funcionament del cronògraf
The chronograph function allows you to measure elapsed time. Your Navitimer features two push-pieces on the side of the case, typically at 2 o'clock and 4 o'clock.
- Inici: Press the upper push-piece (at 2 o'clock) to start the chronograph. The large central seconds hand will begin to move.
- Atura: Press the upper push-piece again to stop the chronograph. The central seconds hand and the minute/hour counters will display the elapsed time.
- Restablir: After stopping the chronograph, press the lower push-piece (at 4 o'clock) to reset all chronograph hands to zero.
- Intermediate Times (Flyback): Some models may feature a flyback function, allowing immediate restart without stopping and resetting. Consult your specific model's detailed instructions if applicable.
Using the Circular Slide Rule (Navitimer Specific)
The Navitimer's iconic bidirectional rotating bezel features a circular slide rule, enabling various calculations such as multiplication, division, speed, distance, fuel consumption, and currency conversions. This function requires practice to master.
- The outer scale (fixed) is the "reference scale," and the inner scale (rotating bezel) is the "movable scale."
- Multiplicació: Align the "10" (or "1") on the inner scale with the first number on the outer scale. Read the result on the outer scale opposite the second number on the inner scale.
- Divisió: Align the divisor on the inner scale with the dividend on the outer scale. Read the result on the outer scale opposite the "10" (or "1") on the inner scale.
- For detailed instructions on specific calculations (e.g., speed, distance, rate of climb/descent), refer to Breitling's comprehensive Navitimer slide rule guide available on their official weblloc.
Manteniment i cura
Neteja
Regular cleaning helps maintain the appearance of your watch.
- For metal bracelets and water-resistant cases, use a soft brush and soapy water. Rinse thoroughly with clean water and dry with a soft cloth.
- For leather straps, avoid prolonged contact with water, moisture, direct sunlight, and cosmetics. Clean with a dry, soft cloth.
Resistència a l'aigua
Your Navitimer has a specific water resistance rating. Ensure the crown and push-pieces are fully screwed down (if applicable) before any contact with water. Do not operate the crown or push-pieces underwater.
- Water resistance is not a permanent characteristic and can be affected by aging gaskets or accidental impacts.
- It is recommended to have the water resistance checked annually by an authorized Breitling service center.
Manteniment
Like any precision instrument, your watch requires periodic servicing to ensure optimal performance and longevity. Breitling recommends a complete service every 3-5 years, depending on usage and environmental conditions.
- Only entrust your watch to an authorized Breitling service center for maintenance and repairs. Unauthorized interventions can void the warranty and compromise the watch's integrity.
Emmagatzematge
When not wearing your watch, store it in a cool, dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields. The original watch box provides excellent protection.
