Introducing the newest addition to the Attesa Lunar range by Citizen: a groundbreaking model that embodies sophistication and innovation. This remarkable timepiece marks a significant advancement as the world’s premier analogue light-powered radio-controlled moon phase watch. 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. 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. — (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.)
