The Breitling Chrono-Matic Cal.11, a name that whispers of a bygone era of horological innovation and daring design, holds a special place in the hearts of vintage watch enthusiasts. This article delves deep into the world of the Breitling Vintage 70ies Chrono-Matic Cal.11, specifically focusing on the highly sought-after reference 7651, a testament to Breitling's pioneering spirit in the realm of automatic chronograph movements. Its rarity, coupled with its undeniable charm, makes it a true grail watch for collectors worldwide.
A Legacy of Innovation: The Chrono-Matic Cal.11
Before we delve into the specifics of the reference 7651, it's crucial to understand the significance of the Chrono-Matic Cal.11 movement itself. In the late 1960s and early 1970s, the watchmaking industry was on the cusp of a revolution. The quartz crisis loomed, threatening the dominance of mechanical movements. Breitling, however, refused to succumb to the tide of quartz. Instead, they spearheaded the development of the Chrono-Matic, a groundbreaking automatic chronograph movement.
Unlike previous automatic chronographs which relied on complex and often unreliable cam-based mechanisms, the Chrono-Matic Cal.11 utilized a revolutionary integrated automatic chronograph caliber. This meant that the chronograph functions were integrated directly into the main movement, rather than being added as a separate module. This resulted in a more compact, efficient, and robust movement, a significant leap forward in chronograph technology. This was achieved through a collaboration between Breitling, Heuer (now TAG Heuer), Buren, and Dubois-Dépraz, a testament to the collaborative spirit needed to overcome the technical hurdles of the time. The resulting movement was a marvel of engineering, showcasing the best of Swiss horological expertise.
The Chrono-Matic Cal.11 wasn't just technologically advanced; it was aesthetically pleasing too. The movement's intricate design, visible through the exhibition casebacks of many models, is a feast for the eyes. The bridges, screws, and other components are meticulously finished, reflecting the high standards of craftsmanship expected from a Breitling timepiece.
The Reference 7651: A Rare Gem Among Chrono-matics
Within the already exclusive world of Breitling Chrono-Matic Cal.11 watches, the reference 7651 stands out as particularly rare. This reference, typically identified as the "Yachting" model, embodies the style and spirit of the 1970s. Its design features often include a distinctive combination of features that set it apart from other Chrono-Matic models.
The 7651 typically boasts a robust stainless steel case, reflecting the sporty and functional nature of the watch. The dial, often in a classic black or blue, is beautifully proportioned, with clear and legible sub-dials for the chronograph functions (hours, minutes, and seconds). The hands, usually baton-style, are elegantly designed for optimal readability. The bezel, often a rotating bidirectional bezel, is a key feature, contributing to the watch's functionality and aesthetic appeal. This rotating bezel, often featuring a tachymeter scale, further enhances the watch's utility for timing events.
