- Description:
- This heliochronometer, called a Gard Clock Hybrid Sundial, is a precision instrument constructed by 3D printing. The dial featured in the photos below has a large equatorial ring 7.7 inches (19.5cm) in diameter with an inner geared ring of 144 teeth. The teeth engage a planetary gear system to a secondary minute dial for accurate time reading. It also uses a curved analemma and nodus vertical plates. The nodus is an oculus with tilt adjustment, casting a ring and spot of light onto the rear analemma. Separate equatorial ring and analemma are made for the Northern and Southern hemispheres. The heliochronometer has longitude adjustment and with the analemma, converts local solar time into civil time. Measured accuracy is less than one minute of time.

- The main hour & latitude crescents are loosely based on the look of the J. D. Gard Heliochronometer.
