In collaboration with our corporate partner, ispace inc., three new limited-edition models were created as part of their HAKUTO-R commercial lunar exploration program. Taking inspiration from their ultimate destination, the moon, these models are designed and equipped with the world’s first analogue light-powered radio-controlled moon phase movement. Featuring the state-of-the-art radio-controlled Eco-Drive Cal. H874 movement, it ensures outstanding accuracy of ±15 seconds per month. Crafted with our revolutionary Super Titanium™ material, these watches boast both durability and refined elegance. This collection is driven by CITIZEN's pioneering "Luna Program," a unique mathematical algorithm, the watch calculates the moon's phase daily using signals from multi-band radio transmitters. This data is seamlessly integrated to automatically adjust and display the moon's phase at the six o’clock position, offering an unparalleled level of precision. Additionally, it introduces the innovative "NS Shift" moon phase display switching function, allowing users to observe the moon's appearance from both the northern and southern hemispheres. Limited to 2,400 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.)
