The Breitling Chronomat GT's dial is more than just a pretty face; it's a meticulously designed instrument panel, a testament to Breitling's long history of crafting high-performance timepieces for professionals. This article will delve into the intricacies of the Chronomat GT dial, focusing specifically on its prominent tachymeter scale and its interaction with the chronograph function. We’ll also explore the broader context of the Chronomat line, touching upon pricing and availability to provide a comprehensive understanding of this iconic watch.
The most striking feature of the Chronomat GT dial is undoubtedly the tachymeter scale. This graduated scale, positioned on the rehaut (the inner bezel ring), is a crucial element for measuring speed. Unlike many tachymeter scales that run from 60 to 500, the Chronomat GT's scale is inverted, running from 500 to 60. This might seem counterintuitive at first, but it's a design choice that enhances readability and contributes to the watch's overall aesthetic. The numbers are clearly marked and easily discernible, even at a glance. This inverted scale, coupled with the dial's clear layout, makes reading the tachymeter incredibly intuitive.
The tachymeter's functionality is intrinsically linked to the chronograph function of the watch. The chronograph's central seconds hand acts as the primary indicator for speed calculations. To use the tachymeter, you start the chronograph when an object begins its measured journey (e.g., a car passing a fixed point). You then stop the chronograph when the object reaches a predefined distance. The position of the chronograph seconds hand on the tachymeter scale will then indicate the speed of the object over that distance, usually expressed in units per hour. For example, if the chronograph hand points to the "100" marking after one minute, the speed is 100 units per hour. If it points to "500" after one minute, the speed is 500 units per hour. This functionality is crucial for various applications, from motorsport to aviation, where precise speed measurements are paramount.
The inverted scale on the Chronomat GT, running from 500 to 60, reflects a common practice in high-end chronographs. While a scale running from 60 to 500 might seem more logical at first glance, the inverted scale offers several advantages. Firstly, it provides a more visually balanced presentation on the dial, integrating seamlessly with the other elements. Secondly, it often results in a more precise reading, as the higher numbers are generally easier to read accurately. The precision of the tachymeter reading is, of course, dependent on the accuracy of the chronograph movement, a factor that Breitling consistently prioritizes in its manufacturing process.
