Looking back at the roots of the clock, rather than simply measuring the exact time, It served as an astronomical instrument to observe the motion of the moon and stars in the sky. 

This time, Harriot intends to create and present a moon phase design that contains the movement of the sky among many functions of the watch. 

 Have you ever heard of 'Angbu Ilgu' invented by Jang Young-sil in the Joseon Dynasty? Considering the principle that the sun in the sky moves, it is installed everywhere, It is a clock made so that people can easily recognize the time. The Ilgu (日晷) of Angbu ilgu means sundial, and it is easy to call and has a common point that expresses the movement of the sky. Although it means sundial, I thought what if I decided to name it Harriot's new collection.

The Ilgu collection is also available in 40mm. 

Moon phase literally means (moonphase / moon-face) and is a function that indicates the phase of the moon. It was a practical function mainly used by navigators and astronomers in the past, Currently, it is mostly mounted for aesthetic purposes rather than functional purposes. But for Harriot’s supporters who like classic watches, It was also the design and function I wanted to show first. 

To be precise, it rotates every 29.5 days, expressing the phases of the new moon, the upper moon, the full moon, the lower moon, and the old moon.
