Breitling, a name synonymous with aviation and precision timekeeping, has a long and storied history of developing and utilizing its own in-house movements. However, the brand has also leveraged the capabilities of third-party manufacturers, notably Sellita, to power some of its models. This article focuses specifically on the Sellita SW300 movement used in certain Breitling watches, exploring its specifications, comparing it to Breitling's own calibers, and addressing the broader context of Breitling's movement choices.
The Sellita SW300 is a workhorse movement, a reliable and cost-effective alternative to some of Breitling's more expensive in-house calibers. Its significance lies in its role as a bridge, offering a balance between affordability and the quality expected from a Breitling watch. Currently, the SW300 exists in a single variation, a significant departure from the diverse range of calibers Breitling itself offers. Understanding its place within the Breitling ecosystem requires examining both its advantages and limitations.
The Sellita SW300: A Closer Look
The Sellita SW300 is often described as a "copy" of the ETA 2892-A2, a highly regarded movement known for its robustness and accuracy. However, it's more accurate to describe it as a highly evolved and improved version based on the ETA's design. While sharing a similar architecture, the SW300 boasts several enhancements. One key difference is the jewel count: the SW300 features 25 jewels compared to the ETA 2892-A2's 21. This increase in jewels contributes to reduced friction and wear, potentially leading to enhanced longevity and performance. This is a significant improvement, especially given the increased demand for durability in watches intended for everyday wear.
The SW300's automatic winding mechanism is efficient and reliable, ensuring consistent power reserve. While the exact power reserve varies slightly depending on the specific implementation and usage, it generally falls within the typical range for automatic movements of this type. The movement's relatively high beat rate (28,800 vibrations per hour) contributes to smoother second hand movement and improved accuracy. The SW300 also incorporates features designed to improve shock resistance and overall robustness, making it a suitable choice for watches that might be subjected to moderate levels of impact.
Comparing the Sellita SW300 to Breitling's In-House Calibers
While the Sellita SW300 serves a crucial role in making certain Breitling watches more accessible, it differs significantly from the brand's own in-house movements, particularly those like the Breitling Caliber 17. The Breitling Caliber 17, for instance, represents a higher level of sophistication and often incorporates features not found in the SW300.
Breitling 17 Caliber Movement: The Breitling Caliber 17, often found in the Breitling Navitimer series, is a highly regarded chronograph movement. It is characterized by its superior finishing, more complex architecture incorporating chronograph functions, and often includes bespoke features designed and manufactured by Breitling. The Caliber 17 reflects Breitling's commitment to horological excellence and is generally associated with higher price points.
