The Breitling Navitimer, a watch synonymous with aviation history and horological excellence, demands respect and understanding. This comprehensive guide serves as a virtual manual, encompassing various aspects of owning and operating a Breitling Navitimer, particularly focusing on the manual-wind models. While specific instructions may vary slightly depending on the exact model and year of production (e.g., Navitimer Automatic vs. Navitimer 8, or variations within a specific generation), the core principles remain consistent. This article will cover general operation, time setting, potential issues, and resources for further assistance. The random sequence of numbers provided (Navitimer 4 2 4 6 4 2 4 6 6 2 10 8 Chronometre Navitimer 4 2 4 6 4 2 4 6...) appears unrelated to the functioning of the watch and will not be addressed directly within the operational instructions.
I. Understanding Your Breitling Navitimer Manual-Wind Movement:
The heart of your Breitling Navitimer manual-wind watch is a mechanical movement, a marvel of miniature engineering. Unlike automatic movements that wind themselves through the wearer's motion, a manual-wind movement requires you to manually wind the mainspring to power the watch. This process is typically performed using the crown, located at the right side of the case. The precise mechanism and number of turns required may vary between models, but the general principle remains the same. Regular winding ensures consistent power reserve and accurate timekeeping.
II. Breitling Navitimer User Manual: Essential Functions
* Winding the Watch: Locate the crown. Generally, unscrewing the crown (if it's screw-down) is the first step. Then, turn the crown clockwise until you feel resistance. Over-winding should be avoided, as it can damage the movement. Consult your specific Breitling Navitimer manual for the recommended number of turns. A fully wound watch typically provides a power reserve of approximately 40-70 hours, depending on the caliber.
* Setting the Time: Once the watch is wound, pull the crown out to the first position. Turning the crown clockwise will advance the time. Turning it counter-clockwise will move the time backward. Push the crown back into its original position to lock the time setting.
* Chronograph Functions (if applicable): Many Breitling Navitimers incorporate a chronograph function. This allows you to measure elapsed time. Typical chronograph controls include:
* Start/Stop: Pressing the pusher at the 2 o'clock position starts and stops the chronograph seconds hand.
* Reset: Pressing the pusher at the 4 o'clock position resets the chronograph hands to zero.
* Slide Rule Bezel: The iconic feature of the Navitimer is its rotating bezel with a slide rule. This allows for quick calculations related to aviation, such as flight time, fuel consumption, speed, and distance. Mastering the slide rule requires dedicated study and practice, and numerous resources are available online to assist in this.
III. Breitling Navitimer Owners Manual: Care and Maintenance
* Regular Winding: Wind your Breitling Navitimer regularly, even if you wear it daily. This ensures consistent power and prevents the watch from stopping.
* Avoid Shocks and Impacts: Mechanical movements are delicate. Protect your watch from strong shocks and impacts.
