The observation tower is made by analogy with the ancient Indian observatory called "Jantar Mantar", and is a combination of an observation deck and a sundial.

 

The stairway is the hand of the sundial, and the half-ring located perpendicularly represents the dial, on which divisions are applied. The shadow from the stairs falls on the half-ring of the dial and shows the time.

The design is made with high precision so that the time is displayed to the nearest minute.

​

The observation staircase is located due north, and should be in a clearing free from nearby trees so that no additional shadow is created on the clock.
