Breitling watches, renowned for their robust construction and aviation heritage, employ a sophisticated system of screw-down crowns and buckles. These components, often referred to as "screw pins," play a crucial role in the watch's water resistance and overall functionality. While generally reliable, these mechanisms can occasionally require maintenance or repair, necessitating a thorough understanding of their intricacies. This article will delve into the world of Breitling screw pins, exploring common issues, troubleshooting techniques, and the importance of proper maintenance to ensure the longevity and performance of your prized timepiece. We will also examine where to source replacement parts and tools, referencing the vast selection available online, such as eBay's extensive catalog of Breitling watch tools and repair kits offering free shipping on many items.
Understanding the Breitling Screw-Down Crown: The Heart of Water Resistance
The Breitling screw-down crown is a vital component responsible for sealing the watch case, preventing water ingress. Unlike push-pull crowns found in simpler watches, the screw-down crown requires manual screwing to secure it in place. This added step significantly enhances water resistance, making Breitling watches suitable for various activities, including swimming and diving (depending on the specific model's water resistance rating).
The mechanism itself is relatively straightforward: the crown threads onto the watch case tube. When screwed tightly, a gasket, usually made of a durable, waterproof material like Viton, compresses, creating a hermetic seal. This seal is critical to maintaining the watch's water resistance. However, the very nature of this mechanism, involving repeated screwing and unscrewing, makes it susceptible to wear and tear over time.
Breitling Screw-in Crown Repair: Addressing Common Problems
Several issues can arise with Breitling screw-down crowns, necessitating repair or replacement. Here are some of the most common problems:
* Stripped Threads: This is perhaps the most frequent problem encountered. Over-tightening the crown, using excessive force, or attempting to screw it in while it's misaligned can strip the threads on either the crown itself or the case tube. This renders the crown unusable and compromises water resistance. Repair involves replacing either the crown or the case tube, or both, depending on the extent of the damage.
* Gasket Failure: The gasket is the crucial element providing the waterproof seal. Over time, the gasket can deteriorate due to age, exposure to chemicals, or repeated compression. A failed gasket will compromise the watch's water resistance, leading to potential water damage. Replacing the gasket is a relatively straightforward repair, best performed by a qualified watchmaker.
* Crown Stem Issues: The crown stem is the internal component that connects the crown to the watch's movement. Damage or wear to the stem can prevent the crown from screwing in properly or can cause it to become loose. Repair often requires replacing the entire stem.
* Difficulty Winding or Setting: If the crown feels stiff, difficult to wind, or resists setting the time, it could indicate several issues, including a worn crown, a damaged stem, or problems within the movement itself. This requires professional attention.
