Design
- Case and Dial
- The timepiece is housed in a circular aluminum and iron case designed for integration into aircraft instrument panels. The mounting flange includes four holes, allowing the clock to be fixed directly into the cockpit. The front is dominated by a black dial featuring bold Arabic numerals. A rotating bezel surrounds the dial, marked for intervals, enabling the user to calculate flight time. The auction description notes that the clock glass is a replacement and identifies a crack in the bezel specifically at the 60-second marker. Despite these historical repairs and evidence of usage, the object remains in functional state.
