The world of luxury watches is filled with intricate mechanisms and finely crafted components. Breitling, a renowned name in the industry, is particularly known for its robust and functional timepieces, often featuring sophisticated crown and case designs. One common query among Breitling owners, particularly concerning older models or those experiencing issues, revolves around the crown and its interaction with the case – specifically, the "Possiur screw," a term often used (though perhaps not entirely accurate) to describe the mechanism securing the crown. This article will delve into the complexities of Breitling's crown systems, focusing on potential problems, repair options, and the importance of proper maintenance. We'll explore the "Possiur screw" concept in the context of Breitling's diverse range, examining the differences between integrated and separate case designs and addressing common issues like crowns that don't fully screw in.
The Breitling's Screw Lock Push: A Secure Feature
Many Breitling watches, especially those designed for professional use or water resistance, incorporate a screw-down crown. This isn't simply a crown that threads into the case; it's a carefully engineered system designed to ensure water tightness and protect the movement from the elements. The process typically involves unscrewing the crown counter-clockwise before adjusting the time or date, and then screwing it back clockwise until it's firmly secured. The "click" or resistance felt during this process indicates a proper seal. This screw-down mechanism, sometimes referred to (inaccurately in some contexts) as a "Possiur screw" system, is a critical feature for maintaining the watch's water resistance rating.
The design and execution of this system vary across Breitling's models. Higher-end models might use more complex and robust systems, potentially involving multiple gaskets and precisely machined components. More affordable models, like some Aeromarine series watches, may employ a simpler, yet still effective, design. The key difference often lies in whether the crown tube is an integrated part of the case or a separate component. This detail is crucial when it comes to repairs.
Crown Doesn't Fully Screw In: A Common Problem
One of the most common problems reported by Breitling owners is a crown that doesn't screw in fully or smoothly. This can be caused by several factors:
* Damaged Threads: The threads on the crown or the case tube can become damaged due to wear and tear, accidental impacts, or improper handling. Over-tightening the crown is a frequent culprit. Damaged threads prevent the crown from screwing in properly, leading to a compromised seal and potential water ingress.
* Dirt or Debris: Dust, dirt, or other debris can accumulate in the threads, hindering smooth operation. This is particularly common in watches exposed to harsh environments. Cleaning the threads carefully can often resolve this issue.
* Worn Gaskets: The gaskets, which are crucial for maintaining water resistance, can degrade over time due to age, exposure to chemicals, or compression. A worn gasket will not provide a proper seal, even if the crown screws in fully. Replacing the gaskets is essential for restoring water resistance.
