The Breitling Navitimer, a legendary chronograph celebrated for its iconic slide rule bezel and enduring design, has a rich history intertwined with various movements. While the in-house Breitling B01 caliber has taken center stage in recent years, the ETA movements, particularly the Valjoux 7750-based calibers, played a significant role in the Navitimer's accessibility and widespread popularity for decades. Understanding the differences between these movements is crucial for anyone considering a Navitimer purchase. This article will delve into the nuances of the Breitling Navitimer with ETA movements, comparing them to the B01 and exploring various aspects of this iconic watch.
Breitling Navitimer ETA vs B01: A Tale of Two Movements
The core distinction lies in the origin and manufacturing of the movements. The ETA movements, primarily variations of the highly regarded Valjoux 7750, are sourced from ETA, a Swiss movement manufacturer now a part of the Swatch Group. The Breitling B01, on the other hand, is a completely in-house manufactured movement, representing a significant investment in vertical integration and a testament to Breitling's commitment to horological excellence.
ETA-powered Navitimers: These watches often represent a more accessible entry point into the Navitimer family. The use of ETA movements allowed Breitling to offer the iconic design at a more competitive price point, making the Navitimer available to a wider range of enthusiasts. While not possessing the same level of prestige as the in-house B01, ETA-powered Navitimers are still highly regarded for their reliability and accuracy. Many collectors appreciate the historical significance of these movements, recognizing their role in the Navitimer's legacy. Common ETA movements found in Navitimers include modified versions of the Valjoux 7750, offering chronograph functionality with date display.
Breitling Navitimer 01 (B01): The In-House Powerhouse
The Breitling Navitimer 01 signifies a shift towards greater vertical integration and a renewed focus on in-house manufacturing. The B01 caliber is a high-quality, column-wheel chronograph movement known for its robustness, precision, and sophisticated design. It offers a higher level of finishing and features compared to the ETA movements, including improved power reserve and often more intricate decoration visible through the exhibition caseback. The B01 movement embodies Breitling's commitment to creating a truly exceptional watch, reflecting the brand's heritage and technical prowess. The higher price point reflects the significant investment in research, development, and manufacturing involved in producing this caliber.
Hands-On Breitling Navitimer B01 (Referencing Greg Bedrosian's Review):
Greg Bedrosian's July 21, 2021, review of the Breitling Navitimer B01 offers valuable insights into the experience of wearing a watch powered by this in-house movement. The dimensions he cites (43 x 14.2 x 49.1mm) highlight the substantial presence of the watch on the wrist, a characteristic often associated with the Navitimer's bold design. The stainless steel construction and 30m water resistance provide a balance between durability and practicality. While the review doesn't explicitly detail the movement's performance, it implicitly underscores the overall quality and craftsmanship expected from a watch featuring the B01 caliber. The review likely focuses on the design, wearability, and overall aesthetic appeal of the watch, aspects that are equally important to potential buyers.
