Watch Collection: Curation & Photography Guide

The Navitimer reference 806 is a notable early iteration of Breitling's slide rule chronograph, distinguished by its comprehensive circular slide rule bezel. This reference established many of the visual and functional characteristics that would define the Navitimer line for decades. It represents a foundational piece in the development of the brand's instrument watches, designed for calculations relevant to navigation.

The watch features a 40 mm stainless steel case, housing a manual-wind Venus 178 column-wheel chronograph caliber. This movement provides a power reserve of approximately 45 hours. The dial is black, protected by an acrylic crystal, and the watch offers a water resistance of 30 meters. The bi-directional rotating bezel is integral to the slide rule function.

For collectors, the reference 806 is significant as an early example of the Navitimer, appealing to those interested in the historical progression of aviation-related timepieces. Its production span saw variations in dial printing and sub-dial configurations, which are points of interest for specialized collectors. The model's enduring design has influenced subsequent generations of the Navitimer.

The Grönefeld 1941 Remontoire is a distinguished offering from the independent Dutch watchmakers, Tim and Bart Grönefeld. It represents their commitment to traditional haute horlogerie combined with a distinctive contemporary aesthetic, positioning itself as a significant piece within their limited production portfolio.

The timepiece features a constant force mechanism, or remontoire d'égalité, integrated into its hand-wound movement, ensuring consistent power delivery to the escapement for enhanced accuracy. The movement, visible through a sapphire case back, is meticulously finished with polished bevels, circular graining, and Geneva stripes. The case is typically crafted from precious metals, housing a dial designed for legibility and understated elegance.

For collectors, the 1941 Remontoire is valued for its technical sophistication and the brothers' dedication to artisanal craftsmanship. Its limited production numbers and the inclusion of a complex constant force complication contribute to its desirability and long-term appeal within the independent watchmaking segment.
