Inspired by the celestial beauty of the moon, this exceptional timepiece embodies the spirit of exploration and innovation. Drawing inspiration from the journey of the HAKUTO-R lunar lander, the design reflects both the moon’s serene elegance and the cutting-edge technology that makes such missions possible—serving as a tribute to discovery, precision, and the pursuit of the extraordinary. The watch features a yellow dial subtly accented with metallic pink highlights, offering an understated yet refined aesthetic. Enhancing its celestial theme, a moon phase window elegantly showcases a golden moon—rendered against a deep black background using pearl ink—rising from the darkness of a star-filled sky. Echoing the ethereal beauty of cherry blossoms, the case is crafted from Sakura Pink Duratect Super Titanium™, paired with a matching Duratect DLC bracelet. Powered by Citizen’s Eco-Drive technology and enhanced with Radio-Controlled precision, this special edition debuts the new H874 calibre. This innovative movement introduces the “Luna Program,” a unique lunar tracking function that enables accurate moon age calculation without the need for manual adjustment. Additional features include NS Shift functionality for toggling between northern and southern hemisphere moon phase displays, automatic station selection, scheduled and on-demand time signal reception, a perpetual calendar, Direct Flight for simplified time zone changes, 24-city world time, and water resistance up to 100 metres. Limited to 2,100 pieces worldwide. (Please note that the radio-controlled functionality will not work in Australia due to the absence of radio transmitting stations within range. These stations are exclusive to four regions: Europe, USA, China and Japan. However, this does not affect manual time adjustment. Please refer to your instruction manual for guidance.)
