The Breitling Navitimer, particularly the reference 1806, holds a revered position in the world of horology. Its distinctive slide rule bezel and robust design have captivated enthusiasts for decades. While the movement and case garner much attention, a crucial, often overlooked component contributes significantly to the watch's integrity and aesthetic appeal: the plexi armierungsring, or crystal retaining ring. This article explores the significance of this seemingly small part within the context of the 1969 Breitling Chrono-Matic 1806, delving into its function, material, potential issues, repair costs, and the overall impact on the watch's value and collectability.
The Breitling 1806, a 48mm behemoth for its time, is a prime example of the brand's commitment to precision and functionality. Its Chrono-Matic Caliber 11 movement, a landmark achievement in automatic chronograph technology, is justly celebrated. However, the watch's overall aesthetic is inextricably linked to its acrylic crystal (plexiglas) and the metal ring that secures it. The armierungsring, typically made of stainless steel, sits beneath the crystal, creating a secure and even pressure distribution. This prevents the crystal from popping out due to pressure changes or impacts, a crucial feature given the watch's size and intended use.
The Function of the Armierungsring:
The primary function of the armierungsring is to firmly hold the acrylic crystal in place. Acrylic, while possessing excellent scratch resistance compared to some modern materials like sapphire, is inherently more susceptible to cracking under significant impact. The armierungsring acts as a buffer, distributing the force of an impact across a wider surface area, reducing the likelihood of the crystal shattering or cracking. It also ensures a consistent and secure fit, preventing dust and moisture from entering the case and potentially damaging the delicate movement. A properly fitted armierungsring is essential for maintaining the watch's water resistance, although the 1806 is not known for exceptional water resistance compared to modern divers' watches.
Material and Construction:
The armierungsring on a vintage Breitling 1806 is typically crafted from stainless steel. This material offers a robust and durable solution, capable of withstanding the stresses associated with daily wear and tear. The ring itself is usually a simple, precisely engineered component, designed to fit snugly within the case and securely grip the crystal. Its construction is critical; imperfections in the machining or material can lead to issues with crystal retention and overall watch integrity.
Common Issues and Repair Considerations:
Over time, the armierungsring on a vintage Breitling 1806 can suffer from several issues:
* Corrosion: Exposure to moisture and atmospheric elements can lead to corrosion, particularly on the underside of the ring where it contacts the crystal. This can weaken the ring, making it less effective at holding the crystal in place.
* Damage: Impacts or accidental drops can deform or damage the armierungsring, compromising its ability to provide adequate crystal retention.
* Loose Fit: Over time, the ring might loosen, leading to a poorly secured crystal and potential water ingress.
These issues necessitate repair or replacement. Finding a genuine Breitling 1806 armierungsring can be challenging, and sourcing replacement parts is a significant aspect of vintage watch ownership. This leads us to the crucial topic of Breitling parts prices and service costs.
