The Breitling SuperOcean collection, renowned for its robust build and exceptional water resistance, has long been a favorite among divers and watch enthusiasts alike. But beyond its striking aesthetics and impressive functionality lies the beating heart of the watch: the movement. Understanding the movement powering your SuperOcean is crucial to appreciating its performance, longevity, and overall value. This article delves deep into the mechanics powering the various SuperOcean models, focusing primarily on the Breitling Caliber 17 and its foundation in the ETA 2824-2. We'll explore the differences across various case sizes, like the Breitling SuperOcean 42 vs 44, and examine the performance of this reliable workhorse in models such as the Breitling SuperOcean Automatic 42, Breitling SuperOcean Automatic 46, and the smaller Breitling SuperOcean 36.
The Heart of the Matter: The Breitling Caliber 17
At the core of most Breitling SuperOcean models lies the Breitling Caliber 17. This automatic movement isn't a proprietary Breitling design; instead, it's a modified version of the highly respected ETA 2824-2. This base movement is renowned for its reliability, robustness, and widespread use within the watchmaking industry, providing a solid foundation for Breitling's modifications. The ETA 2824-2 is a workhorse, known for its resilience and accuracy, making it an ideal choice for a dive watch that needs to withstand significant stress.
The Breitling Caliber 17 builds upon the ETA 2824-2's strengths, adding Breitling's own finishing touches and incorporating a quick-set date complication. This allows for easy adjustment of the date without having to cycle through the entire day, a practical feature for everyday wear. The modifications made by Breitling often include enhanced decoration, such as Côtes de Genève (Geneva stripes) and perlage, which are visible through the exhibition caseback on many SuperOcean models. These decorative elements elevate the Caliber 17 beyond a simple workhorse movement, showcasing a level of craftsmanship that reflects Breitling's commitment to quality.
Breitling Caliber 17 Automatic Movement: A Closer Look
The Breitling Caliber 17 is an automatic movement, meaning it winds itself through the natural movement of the wearer's wrist. This eliminates the need for manual winding, offering convenience and ease of use. It boasts a power reserve of approximately 40 hours, meaning it will continue to run for about two days after being removed from the wrist. This power reserve is perfectly adequate for most users, ensuring the watch remains operational even if it's not worn consistently.
The movement operates at a frequency of 28,800 vibrations per hour (4 Hz), contributing to its relatively smooth sweep of the second hand. While not as high a frequency as some higher-end movements, this frequency provides a good balance between accuracy and power efficiency. The accuracy of the Caliber 17 is generally within acceptable COSC (Contrôle Officiel Suisse des Chronomètres) standards, though not all Breitling SuperOcean models are COSC-certified. COSC certification guarantees that the movement meets stringent accuracy standards, a testament to the precision of the watchmaking.
