The Breitling SuperOcean collection, renowned for its robust build and diving capabilities, often features the Breitling Caliber 17 (A17390) movement. This seemingly simple designation belies a fascinating story of modification and refinement, showcasing Breitling's approach to leveraging established base movements to create their own distinct calibers. This article will delve into the specifics of the A17390, exploring its origins, specifications, performance, and its place within the broader context of the SuperOcean line, particularly the Steelfish models.
Breitling A17390 Specs:
At the heart of the A17390 lies the ETA 2824-2, a highly regarded and widely used automatic movement known for its reliability and accuracy. However, Breitling doesn't simply slap its name on an off-the-shelf component. The ETA 2824-2 undergoes significant modifications before it earns the designation "Breitling Caliber 17." While the exact nature of these modifications is often proprietary information, we can infer certain enhancements based on Breitling's reputation and the overall performance of the A17390.
These modifications likely include:
* Decoration: Breitling is known for its meticulous finishing. The A17390 will feature Côtes de Genève (Geneva stripes), perlage (circular graining), and possibly other decorative elements visible through the exhibition caseback (depending on the specific SuperOcean model). This enhances the visual appeal and reflects Breitling's commitment to quality.
* Regulation: Breitling likely performs rigorous testing and regulation of the movement to ensure accuracy and chronometric performance within their specified tolerances. This meticulous process contributes to the overall reliability and precision of the watch.
* Components: While the base architecture remains that of the ETA 2824-2, Breitling may incorporate higher-grade components or materials in certain areas to improve durability and longevity. This could include enhanced lubricants, stronger springs, or other subtle yet impactful changes.
* Testing: The movement undergoes extensive testing to meet Breitling's stringent quality control standards. This ensures that each watch leaves the factory meeting the high expectations associated with the brand.
The key specifications of the Breitling Caliber 17 (A17390) generally include:
* Movement Type: Automatic, self-winding
* Base Movement: ETA 2824-2
* Jewels: 25
* Frequency: 28,800 vibrations per hour (4 Hz)
* Power Reserve: Approximately 38-42 hours (depending on usage and modifications)
* Functions: Hours, minutes, seconds, date
* Finishing: Decorated with Côtes de Genève, perlage, and other embellishments.
It's important to note that these specifications are general; slight variations might exist depending on the specific year of production and any further internal modifications Breitling may have implemented.
