The Breitling Navitimer Handaufzug 806 is a legend, a cornerstone of horological history, and a highly sought-after piece among vintage watch enthusiasts. Its iconic design, coupled with its robust mechanical movement, has cemented its place as a timeless classic. But one element often overlooked, yet critically important to the watch's aesthetic integrity and overall experience, is the plexiglass crystal. This article delves deep into the world of the Breitling Navitimer Handaufzug 806 plexiglass, exploring its significance, characteristics, and the importance of sourcing the correctly domed crystal for an authentic and optimal experience.
The Significance of the Plexiglass Crystal:
The original Breitling Navitimer Ref. 806 and its close cousin, the Cosmonaute Ref. 809, were fitted with a specific type of plexiglass crystal: a correctly domed, subtly curved piece that perfectly complements the watch's design. This isn't just a matter of aesthetics; the dome itself contributes to the overall feel and character of the timepiece. Modern sapphire crystals, while scratch-resistant, lack the subtle warmth and gentle distortion of light that the original plexiglass provides. This subtle distortion, a characteristic of the material and its curvature, adds a vintage charm and a unique visual depth that's often described as "organic" or "alive." It's a characteristic that many collectors actively seek out, appreciating its contribution to the watch's character.
The plexiglass crystal on the 806 isn't just about looks; it also played a crucial role in the watch's functionality and durability in its era. While less scratch-resistant than sapphire, plexiglass is significantly more impact-resistant. This was a vital consideration given the intended use of the Navitimer as a pilot's watch, where accidental bumps and knocks were a real possibility. Furthermore, if damaged, plexiglass is relatively inexpensive and easier to replace compared to sapphire, making it a practical choice for a tool watch.
Correctly Domed – A Matter of Precision:
The term "correctly domed" is crucial when discussing the plexiglass crystal for the Breitling Navitimer 806. It's not simply a matter of finding any old plexiglass dome; the curvature, thickness, and overall profile must be accurate to match the original specifications. Improperly domed crystals can alter the watch's appearance significantly, creating an unnatural look that detracts from its vintage appeal. A poorly fitted crystal can also lead to issues with water resistance and even affect the functionality of the chronograph pushers.
Finding the correct plexiglass crystal requires meticulous attention to detail. Reputable suppliers specializing in vintage watch parts meticulously measure and reproduce the original specifications, ensuring the replacement crystal perfectly matches the original in terms of curve, thickness, and overall dimensions. They understand the nuances of the 806's design and the importance of preserving its historical accuracy.
