Full-Cataloguing
• Exceptionally complicated model with equation of time, sunrise, and sunset calibrated with perpetual calendar
• Discontinued Collection
-Launched in the 1990s and named after founder Jules Louis Audemars (1851-1918), the Jules Audemars Collection was a conscious decision by the brand to move away from the sportif appeal of the Royal Oak model to a traditional timeless design featuring complicated timepieces in round cases. Jules Audemars was a technical innovator, known for making complex movements and this collection honored his skills and craftsmanship. The line includes complications from perpetual calendars, tourbillons, minute repeaters and like the present timepiece, Equation of Time.
-The reference 26003BC combines a perpetual calendar with moon phase and equation of time - one of the rarest complications found in timepieces. The watch shows the difference between the time on the watch (mean time) and the true solar time shown by the sun in the sky. Due to the Earth’s elliptical orbit and tilted axis, a solar day is not exactly 24 hours, with solar time varying by plus 15 minutes to minus 15 minutes throughout the year. It uses an independent hand with sun symbol and outer scale on the dial to calculate the number of minutes to add or subtract. The present model is calibrated to Rostov-on-Don and its solar zenith of 12h21, indicating the time of sunrise and sunset with remarkable accuracy for each day of the year linked with the perpetual calendar.
-The Jules Audemars Equation of Time is a legacy watch reflecting exceptional Swiss watchmaking acting as a bridge between the past and the future. The watch is offered with at no reserve.
