The Breitling 24, or more accurately, the movements designated as utilizing the Caliber 24, represent a significant chapter in the brand's history, showcasing their commitment to reliable and robust chronographs. While not a single, uniquely Breitling-designed movement, the Caliber 24 designation encompasses a family of automatic chronograph movements, primarily sourced from ETA and Sellita, which have powered numerous Breitling watches across various collections. Understanding this Caliber 24, its variations, and its place within the broader landscape of Breitling movements is key to appreciating the brand's horological heritage and its current offerings.
This article will explore the intricacies of the Breitling 24 caliber, examining its technical specifications, variations, reliability, and its position within the wider context of Breitling's watchmaking philosophy, encompassing their commitment to chronometry, their movement warranties, and comparisons with other Breitling movements like the in-house B20.
Breitling 24 Caliber: Technical Specifications and Functionality
At its core, the Breitling 24 caliber is an automatic chronograph movement. This means it winds itself through the natural movement of the wearer's wrist, eliminating the need for manual winding. The "chronograph" function allows for precise measurement of elapsed time, typically using a central chronograph seconds hand and subsidiary dials for minutes and hours of elapsed time. The Caliber 24 also often incorporates a second time zone function, a highly practical feature for frequent travelers.
The key specifications commonly associated with movements under the Caliber 24 umbrella include:
* Automatic Winding: Self-winding mechanism for convenient operation.
* Chronograph Function: Enables precise timekeeping of elapsed intervals.
* Second Time Zone: Displays a second time zone simultaneously.
* Approximate Power Reserve: Around 42 hours, meaning the watch will continue to run for approximately 42 hours after it's fully wound before needing to be wound again. This is a fairly standard power reserve for automatic movements in this class.
* Frequency: 28,800 vibrations per hour (VPH), or 4 Hz. This is a relatively common frequency for automatic movements, contributing to accurate timekeeping.
* Jewels: Typically 25 jewels. Jewels are synthetic rubies used in the movement to reduce friction and wear, thus increasing longevity and accuracy.
Breitling Watches Utilizing the Caliber 24:
The Caliber 24, due to its versatility and robust construction, has been employed across a range of Breitling watch collections over the years. Pinpointing the exact models is challenging, as Breitling's model naming conventions and internal movement designations can be complex. However, many mid-range to entry-level chronograph models from Breitling have historically utilized variations of this Caliber 24. Researching specific Breitling watch model numbers will reveal whether they utilize this movement.
