The pre-owned Breitling Montbrillant Datora, specifically reference A21330, holds a special place in the hearts of many watch collectors. Its enduring appeal stems from a potent combination of factors: the instantly recognizable Breitling aesthetic, its impressive complication, its robust build quality, and its relative rarity in the pre-owned market. This article will delve into the specifics of this remarkable timepiece, exploring its design, functionality, history, and place within the broader context of Breitling Navitimer models. We will also touch upon factors to consider when purchasing a pre-owned example and provide guidance on navigating the market for the best price.
Unmistakable Breitling DNA:
The Breitling Montbrillant Datora, while not technically a Navitimer in the strictest sense (it lacks the iconic circular slide rule bezel), undeniably carries the Breitling brand's signature design language. The robust case, typically in stainless steel, exudes a sense of rugged elegance. Its substantial size (typically around 40mm to 42mm depending on the specific reference) commands attention without being overly bulky. The dial, often featuring a clean and uncluttered layout, is punctuated by clear, legible numerals and hands, a hallmark of Breitling's commitment to functionality. This clarity is particularly crucial given the Datora's complex functionality, ensuring ease of use despite its intricate mechanism. The finishing is typically of a high standard, with brushed and polished surfaces creating an appealing contrast.
The Datora Complication: A Perpetual Calendar with a Twist
The heart of the Montbrillant Datora lies in its impressive perpetual calendar complication. Unlike simpler date displays, a perpetual calendar automatically adjusts for the varying lengths of months, including February's leap year adjustments. This eliminates the need for manual corrections, a significant advantage for a watch intended for daily wear. However, the Datora takes this a step further. It's not just a simple perpetual calendar; it's a *rattrapante* perpetual calendar. This means it incorporates a split-seconds chronograph function. The rattrapante, or "split-seconds," mechanism allows the chronograph seconds hand to be stopped momentarily while the main chronograph hand continues to run, enabling precise measurement of intermediate times within a larger time interval. This double complication is what sets the Datora apart and contributes significantly to its collector value. The integration of these two functions within a single movement is a testament to Breitling's horological expertise.
Movement and Reliability:
The Montbrillant Datora typically houses a high-quality automatic movement, often a Breitling caliber based on a modified ETA or Venus base movement. These movements are known for their reliability and robustness, capable of withstanding the rigors of daily wear. While specific movements vary across different reference numbers, the level of finishing and precision is generally consistent with Breitling's reputation for producing durable and accurate timepieces. Regular servicing by a qualified watchmaker is essential to maintain the movement's accuracy and longevity. This is especially important for a complicated watch like the Datora, with its intricate perpetual calendar and rattrapante mechanism.
