Breitling A17320 Specs:
The Breitling A17320 is a self-winding (automatic) chronograph movement. While Breitling doesn't publicly release detailed specifications sheets for all its movements in the same way some manufacturers do, information gathered from various sources paints a clear picture. Key features generally include:
* Caliber: A17320 (often referred to as a modified ETA 7750)
* Jewels: Typically 25 jewels, a standard number for high-quality automatic chronograph movements. Jewels reduce friction and wear on the movement's components, contributing to longevity and accuracy.
* Power Reserve: Around 42-48 hours. This indicates how long the watch will run on a full wind before needing to be rewound. Variations might exist depending on usage and winding efficiency.
* Frequency: Typically 28,800 vibrations per hour (vph) or 4 Hz. This represents the speed at which the balance wheel oscillates, influencing the accuracy of the timekeeping.
* Functions: Hours, minutes, seconds, chronograph (stopwatch) with independent seconds hand, and date. The chronograph function allows for precise time measurement up to 12 hours.
* Decoration: While not typically visible through the dial, Breitling movements usually feature some level of decoration, enhancing the overall quality and aesthetic appeal for those who might later service or own a movement.
Breitling A17320 Review:
The A17320 movement's performance receives generally positive reviews from owners and watch enthusiasts. Its reliability is often highlighted, with many reporting accurate timekeeping and dependable chronograph functionality. As a modified ETA 7750, it benefits from the robust design and proven track record of the base movement, a workhorse known for its durability and relatively easy serviceability. This makes it a desirable choice for a watch intended for daily wear and potentially more rigorous activity.
However, it’s important to note that, being a modified ETA, it is not a fully in-house Breitling movement like the manufacture calibers found in some of their higher-end models. This distinction is important for those seeking a watch with a completely bespoke movement. The modifications Breitling implements often improve the movement's finishing, adjust its performance characteristics, and integrate it seamlessly with the specific design of the Superocean Heritage line.
