Just picked up a used but beautiful Breitling Aerospace E79362. Lovely piece, but the backlight doesn't work. I know it's only supposed to come on for a few seconds when you… press the appropriate button, but mine remains stubbornly dark. This experience highlights a common concern among owners of this iconic watch: backlight functionality. This article will delve into troubleshooting this specific issue, exploring the intricacies of the Breitling Aerospace E79362, and comparing it to other models in the Aerospace family.
Understanding the Breitling Aerospace E79362 Backlight System
The Breitling Aerospace E79362, a quartz chronograph, boasts a sophisticated backlight system designed for quick and efficient illumination of the LCD display. Unlike many modern watches with constant-on backlights, the E79362 utilizes a momentary illumination feature. This means the backlight activates only for a short duration upon pressing a specific button, typically the lower-right button. This design choice extends battery life, a crucial factor in a watch packed with features.
The backlight itself is an electroluminescent (EL) backlight, a common technology in watches of this era. EL backlights produce a soft, even glow across the entire display. However, their lifespan is finite, and they are susceptible to failure due to various factors, including age, voltage fluctuations, and physical damage.
Troubleshooting a Non-Functional Backlight
Before assuming the worst, several troubleshooting steps should be taken to diagnose the problem:
1. Battery Check: The most common cause of a non-functional backlight is a low or depleted battery. The Breitling Aerospace E79362 uses a standard battery, typically a Renata 371 or equivalent. Replacing the battery is a relatively straightforward process, often achievable at home with the right tools and a bit of patience. However, it's always advisable to have a qualified watchmaker perform the replacement to prevent damage to the movement.
2. Button Functionality: Ensure the backlight activation button is functioning correctly. Try pressing it firmly and repeatedly. A faulty button might be preventing the signal from reaching the backlight circuit. If the button feels loose or unresponsive, professional servicing may be required.
3. Circuitry Issues: If the battery and button are fine, the problem likely lies within the watch's internal circuitry. A broken connection, damaged component, or faulty integrated circuit (IC) can all prevent the backlight from activating. This requires the expertise of a qualified watch technician, preferably an authorized Breitling service center.
4. EL Backlight Degradation: Over time, the EL backlight itself can degrade. This is a natural process, and replacement might be necessary. This is a more complex repair requiring specialized knowledge and equipment.
Breitling E79362 Price & Market Value
The price of a Breitling Aerospace E79362 varies significantly depending on its condition, age, and included accessories. Pre-owned models can be found at a fraction of the original retail price, making them an attractive option for budget-conscious buyers. However, it's crucial to purchase from reputable sellers and thoroughly inspect the watch before committing to a purchase. Factors influencing price include:
* Condition: A pristine, unblemished watch with original box and papers will command a higher price than a used watch showing signs of wear.
* Completeness: The inclusion of original accessories, such as the instruction manual, warranty card, and original packaging, significantly impacts value.
