Breitling, a name synonymous with aviation-inspired timepieces and robust construction, has a long and fascinating history interwoven with the Incabloc shock protection system. Understanding the role of Incabloc in Breitling watches requires exploring not only its historical significance but also its technical intricacies, particularly concerning its impact on jewel bearing functionality and, ultimately, the value of vintage and pre-owned Breitling Incabloc models on the secondary market. This exploration will delve into the mechanics of Incabloc, its impact on watch longevity and accuracy, and finally, analyze its influence on the price of second-hand Breitling Incabloc watches, referencing the LuxPrice-Index as a benchmark for valuation.
Incabloc Shock Protection: A Revolutionary System
Before the advent of Incabloc, the delicate balance staff – the heart of a mechanical watch's timekeeping mechanism – was highly vulnerable to shocks and impacts. Even minor jolts could misalign the pivots, leading to inaccurate timekeeping or complete failure. This fragility significantly limited the practicality of mechanical watches, particularly in demanding environments like aviation, where Breitling watches found their niche.
Incabloc, a system patented by the Swiss company Portier, revolutionized shock protection. Instead of the balance staff pivots resting directly in jewel bearings, Incabloc introduced a spring-loaded system. This system uses a small, curved spring that cradles the jewel bearing. When a shock occurs, the spring absorbs the impact, preventing the sudden, jarring movement that would otherwise damage the delicate pivots. This ingenious design significantly increased the watch's resistance to shocks and vibrations, allowing for greater durability and reliability.
Breitling's adoption of Incabloc marked a significant step forward in the robustness of their timepieces. It allowed their watches to withstand the rigors of flight, exploration, and other demanding activities, solidifying their reputation for dependable and resilient performance. The integration of Incabloc wasn't merely a cosmetic addition; it was a foundational element in Breitling's commitment to creating watches that could endure even the most extreme conditions. This commitment to robust construction is a key factor in the enduring appeal and value of vintage and pre-owned Breitling Incabloc watches today.
Incabloc Jewel Bearing: The Heart of the System
The Incabloc system's effectiveness is intrinsically linked to the quality and precision of its jewel bearings. These tiny, synthetic ruby or sapphire bearings are strategically placed to minimize friction and wear on the balance staff pivots. The smooth, hard surface of the jewels reduces friction, ensuring that the balance staff can oscillate freely and accurately, even under pressure. The Incabloc system protects these vital jewels from damage, extending their lifespan and maintaining the accuracy of the timepiece.
The choice of jewel material is crucial. Rubies and sapphires are preferred due to their exceptional hardness and resistance to wear. Their inherent properties minimize friction and ensure that the balance staff maintains its precision over extended periods. The precise placement and quality of these jewels are critical factors in the overall performance and longevity of a Breitling Incabloc watch. The meticulous craftsmanship involved in setting these jewels is a testament to the high standards of horological precision that Breitling maintains.
The interaction between the Incabloc shock protection system and the jewel bearings is synergistic. The Incabloc system safeguards the jewel bearings from damage, while the jewel bearings, in turn, ensure the smooth and accurate operation of the balance staff. This symbiotic relationship is key to the superior performance and longevity offered by Breitling watches equipped with this technology.
