The Breitling Navitimer, particularly the early Chronomatic models incorporating the date complication, represents a pinnacle of horological design and engineering. Its iconic slide rule bezel, combined with the sophisticated chronograph functionality and the often-overlooked date window, cemented its place as a classic pilot’s watch and a highly sought-after collector’s item. However, navigating the world of vintage Navitimers, especially those equipped with the Chronomatic movement, requires careful attention to detail. This article will delve into the intricacies of dating early Navitimers, focusing on subtle clues hidden within the bezel, dial, and movement, and addressing some common misconceptions found in popular literature. We will also explore the Navitimer and Cosmonaute timeline and touch upon pricing for similar Breitling models.
Dating Early Navitimers by Bezel Beads:
One of the most effective methods for dating early Breitling Navitimers is by examining the slide rule bezel. The beads, or markers, on the bezel are not uniformly sized or spaced across different production years. While there isn't a definitive, universally accepted chart correlating bead size and year, experienced collectors have developed a keen eye for these subtle variations. Early models often exhibit slightly larger or more irregularly spaced beads compared to later productions. The material of the beads themselves also provides clues; some early bezels used a different material composition that can show signs of wear or discoloration over time differently than later versions. Careful comparison with known dated examples, ideally through high-resolution images and detailed descriptions from reputable sources, is crucial for accurate dating through this method. This requires significant experience and access to a well-documented database of Navitimer bezels.
Identifying an Early Navitimer with Valjoux 72 Movement from the Dial:
The heart of many early Navitimers is the legendary Valjoux 72 movement. Identifying a Navitimer equipped with this movement requires a careful examination of the dial. While the movement itself is not directly visible without opening the case, certain dial characteristics are strongly associated with the Valjoux 72 era. These include specific font styles for the numerals, the arrangement and style of the subdials, and the overall layout of the date window. The color and patina of the dial also play a significant role. Early dials often exhibit a unique discoloration or aging pattern, distinct from later models. Again, comparison with well-documented examples is crucial, and access to detailed images of known Valjoux 72 Navitimers is invaluable for accurate identification. Variations in the printing techniques also provide clues; some early dials show more pronounced imperfections or variations in ink density, further aiding in dating and authentication.
Navitimer & Cosmonaute Timeline:
Understanding the broader context of the Navitimer's history is critical for accurate dating. The Navitimer’s evolution spans several decades, encompassing numerous variations in case size, movement, and features. Creating a precise timeline requires meticulous research into Breitling's production records, which are often not publicly available. However, key milestones, such as the introduction of the Chronomatic movement and the subsequent development of the Cosmonaute, provide significant reference points. The Cosmonaute, a special Navitimer variant featuring a 24-hour dial, debuted in the early 1960s, reflecting a specific period in the evolution of the Navitimer’s design and functionality. Tracing this evolution, and understanding the specific features introduced in each era, is essential for accurate dating of any given Navitimer model.
