The Breitling Navitimer, a legend in the world of aviation watches, is renowned for its robust design and impressive functionality. However, one aspect that often leaves potential buyers searching for answers is the precise lug-to-lug measurement. While Breitling openly publishes the case diameter (42mm or 44mm, depending on the model), the crucial lug-to-lug dimension, which significantly impacts wearability, remains surprisingly elusive. This article delves into the complexities of determining the lug-to-lug measurement for the Breitling Navitimer, specifically focusing on the reference 645315, and explores how this dimension contributes to the watch's overall comfort and suitability for different wrist sizes. We'll also examine the impact of this measurement on strap choices for the Breitling Navitimer watch strap, and its relevance to specific models like the Breitling Navitimer B01 and the Breitling Navitimer Chronograph.
The Elusive Lug-to-Lug Measurement: Why the Lack of Transparency?
The lack of readily available lug-to-lug measurements for Breitling Navitimers, including the 645315, is a common complaint among watch enthusiasts. While case diameter is a standard specification, lug-to-lug measurement, which represents the distance between the lugs (the small protrusions where the strap attaches), is often overlooked by manufacturers. This omission is puzzling, especially considering the crucial role this dimension plays in determining a watch's comfort and wearability. A larger lug-to-lug measurement can make even a smaller-diameter watch feel oversized and uncomfortable on a smaller wrist, while a smaller lug-to-lug measurement on a larger-diameter watch can make it feel more balanced and proportionate.
For the Breitling Navitimer 645315, the lack of official information necessitates a more investigative approach. Online forums and watch communities are awash with anecdotal evidence and estimations, but these lack the precision needed for confident purchasing decisions. This ambiguity highlights a critical gap in information dissemination from manufacturers, leaving potential buyers to rely on second-hand information and potentially inaccurate measurements.
Estimating Lug-to-Lug on the Breitling Navitimer 645315 (42mm & 44mm): A Deep Dive
Without official figures, we must rely on estimations based on similar models and available images. It's crucial to remember that these are approximations, and slight variations can occur due to manufacturing tolerances.
42mm Navitimer Models (Reference 645315 and similar): Based on extensive research across various online forums and detailed images, a reasonable estimate for the lug-to-lug measurement on a 42mm Breitling Navitimer, including the 645315, falls within the range of 49-51mm. This estimate is supported by comparisons to other 42mm watches with similar case designs. However, the exact measurement can slightly vary depending on the specific model and year of production.
44mm Navitimer Models (Reference 645315 and similar): For the larger 44mm Navitimer models, the estimated lug-to-lug measurement is considerably larger, ranging from 51-53mm, possibly even slightly more. This increase is directly proportional to the larger case diameter. The added length significantly impacts wearability, making it more suitable for individuals with larger wrists.
