Understanding this movement is key to appreciating the heritage and craftsmanship behind numerous vintage and even some modern Breitling timepieces. This article will serve as a comprehensive review of the Breitling Caliber 17, addressing its specifications, performance, common variations, and place within Breitling's horological history. We'll delve into aspects often overlooked in simpler reviews, providing a more nuanced understanding of this workhorse movement.
Breitling 17 Movement Review: A Legacy of Reliability
The Breitling Caliber 17 is an automatic mechanical movement, meaning it winds itself through the natural motion of the wearer's wrist. This eliminates the need for manual winding, a feature highly valued for convenience. While not a proprietary in-house movement like many of Breitling's more modern offerings, the Caliber 17 represents a solid foundation built upon a well-established base movement, often sourced from ETA, a renowned Swiss movement manufacturer. This sourcing allowed Breitling to focus on their expertise in watch design and functionality, offering high-quality timepieces at a competitive price point.
The movement's robust construction contributed to its longevity and popularity. Its reliability and relative ease of maintenance made it a favored choice for Breitling, ensuring consistent performance in their watches. While lacking the prestige of a completely in-house movement, the Caliber 17 provided a dependable core for many Breitling models, allowing the brand to concentrate on its signature aesthetic and functionality.
Breitling Caliber 17 Movement Review: Examining the Specifications
While precise specifications can vary slightly depending on the specific watch model and year of production, the core characteristics of the Breitling Caliber 17 remain consistent. Key features often include:
* Automatic Winding: The movement's automatic winding mechanism ensures consistent power reserve through the wearer's movement. This eliminates the need for frequent manual winding.
* Jewels: Typically featuring 17 jewels, although variations might exist. These jewels reduce friction within the movement, contributing to smoother operation and increased longevity. The number of jewels is a common indicator of the movement's complexity and quality. 17 jewels is a respectable number for a movement of this type, indicating a good level of refinement.
* Frequency: The balance wheel typically oscillates at a frequency of 28,800 vibrations per hour (vph), or 4 Hz. This frequency is standard for many automatic movements and contributes to the accuracy of timekeeping.
* Power Reserve: The power reserve, or the amount of time the watch can run on a full wind, generally ranges from 40 to 42 hours. This is a fairly standard power reserve for automatic movements of this era.
* Functions: The Caliber 17 primarily offers hours, minutes, and seconds functions. Some variations may include a date complication, adding a date window to the dial. However, this is not a universal feature across all Caliber 17 equipped watches.
* Finishing: While not typically showcasing elaborate finishing techniques found in high-end movements, the Caliber 17 exhibits a level of craftsmanship suitable for its purpose. The emphasis is on reliability and functionality rather than elaborate decoration.
