The Breitling Navitimer, a horological icon celebrated for its slide rule bezel and enduring design, is available with two distinct movements: Breitling's in-house caliber and the ETA movement. While both share the same aesthetic appeal, a malfunctioning chronograph – specifically a 6.76-second hand that refuses to operate correctly – can be a source of significant frustration for owners. This article will delve into the potential causes behind a malfunctioning 6.76-second chronograph hand on a Breitling Navitimer, regardless of its movement type, and offer guidance on troubleshooting and potential solutions. We'll also touch upon finding authorized Breitling watch stores near you for professional servicing.
Understanding the Navitimer's Chronograph Function:
Before addressing the problem, let's understand the Navitimer's chronograph function. The 6.76-second counter is a distinctive feature, offering a unique subdivision of the chronograph minute counter. This smaller counter allows for highly precise timing measurements. Its malfunction indicates a problem within the chronograph mechanism, irrespective of whether the watch is powered by an in-house or ETA movement.
Possible Causes of a Malfunctioning 6.76-Second Hand:
Several factors can contribute to the failure of the 6.76-second hand on your Breitling Navitimer:
* Mechanical Issues: This is the most common culprit. Within the intricate mechanism of a mechanical watch, numerous components interact to control the chronograph function. A problem with any of these, such as:
* Worn or damaged chronograph gears: Over time, repeated use can wear down the tiny gears responsible for driving the 6.76-second hand. This wear can lead to slippage or complete failure.
* Broken or dislodged levers: The chronograph mechanism relies on a series of levers to engage and disengage the various counters. A broken or dislodged lever can prevent the 6.76-second hand from moving.
* Spring issues: Weak or broken springs within the chronograph module can hinder its proper operation.
* Lubrication problems: Insufficient or improperly applied lubrication can cause friction and impede the smooth movement of the chronograph components.
* Dust or debris: Dust and debris accumulating within the movement can interfere with the delicate mechanisms of the chronograph.
* Movement-Specific Issues: While the external manifestation is the same, the internal causes can differ slightly depending on whether you have an in-house or ETA movement. In-house movements, being more complex and often featuring more advanced technologies, might have slightly different failure points compared to the ETA movements, which are known for their reliability but can still suffer from the mechanical issues mentioned above.
* Impact Damage: A significant impact to the watch, even if seemingly minor, can dislodge components or cause unseen damage within the chronograph mechanism.
* Water Damage: Exposure to water, especially under pressure, can lead to corrosion and damage to the delicate components of the movement, affecting the chronograph's functionality.
* Improper Handling: Rough handling or incorrect operation of the chronograph pushers can also contribute to mechanical issues.
Troubleshooting Steps:
Before rushing to a watchmaker, you can try these basic troubleshooting steps:
1. Check the Chronograph Pushers: Ensure the chronograph pushers are operating smoothly and that they return to their original position after use. A sticky or unresponsive pusher could indicate a problem with the mechanism.
