In March 2022, Wongu-ilyeong, a globe-like sundial made during the 19th century in the Joseon Dynasty, was repatriated from the United States through the efforts of the Korea Heritage Service and the Overseas Korean Cultural Heritage Foundation. This sundial has a total height of about 228 mm, and has time lines and a T-shaped gnomon on its spherical surface with a diameter of approximately 112.2 mm. This sundial is known to have been made by Sang Jik-Hyeon (尙稷鉉, 1849–?), as he carved his seal and the manufacturing date onto its spherical surface. This study investigated Sang, Jik-Hyeon's records from royal governmental literature, and also analyzed the structure of Wongu-ilyeong to understand its usage. We restored the Wongu-ilyeong’s design drawing and manufactured a prototype, with which we measured daytime hours in Jeju, Daejeon, and Seoul. The experimental measurements from three cities showed that the time accuracy of the Wongu-ilyeong, whose minimum time scale is 15 minutes, could be measured within ±7.5 minutes. Wongu-ilyeong is a very rare type of sundial-relic in Korea and overseas, and it is considered to have significant value in the history of science and technology.
