A Deep Dive into the Breitling Caliber 17:
The Breitling Caliber 17 isn't a proprietary movement developed entirely in-house by Breitling. Instead, it represents a modified version of a well-regarded ETA base movement, specifically the ETA Valjoux 7750. This robust and reliable automatic chronograph movement has served as the foundation for countless watches from various brands, and Breitling's Caliber 17 builds upon its strengths. The modification process typically involves adding Breitling's own finishing touches, decorations, and potentially minor adjustments to functionality or aesthetics. This strategy allows Breitling to offer a high-quality, feature-rich chronograph at a comparatively accessible price point, without the significant R&D investment associated with developing a completely in-house movement from scratch.
Technical Specifications and Features:
The Breitling Caliber 17, based on the ETA Valjoux 7750, boasts the following key specifications:
* Automatic Winding: The movement utilizes an automatic winding system, ensuring consistent power reserve through the wearer's natural movements. This eliminates the need for manual winding, offering convenient and effortless timekeeping.
* Chronograph Functionality: As a chronograph, the Caliber 17 offers precise timing capabilities, including independent start, stop, and reset functions for measuring elapsed time. The chronograph typically features three sub-dials, displaying seconds, minutes, and hours of elapsed time.
* Jewels: While the exact number of jewels may vary slightly depending on specific implementations, the Caliber 17 typically features around 25-27 jewels. These jewels minimize friction within the movement, contributing to its smoothness, accuracy, and longevity. Searching for "Breitling 17 jewels" might lead to some confusion, as this doesn't accurately reflect the jewel count of the Caliber 17; it's a detail often misrepresented or misunderstood.
* Frequency: The balance wheel typically oscillates at a frequency of 28,800 vibrations per hour (vph) or 4 Hz, a standard for many high-quality automatic movements. This frequency contributes to better accuracy and smoother second hand movement.
* Power Reserve: The Caliber 17 usually offers a power reserve of approximately 42-48 hours when fully wound. This means the watch will continue to function for a couple of days without being worn.
* Date Display: Most watches featuring the Caliber 17 include a date window, typically positioned at 3 o'clock. This practical feature provides a quick and easy way to check the date.
