Introducing the Citizen 'Tsuki-yomi' Radio-Controlled Moon Phase - the world’s first light-powered radio-controlled moon phase movement. To celebrate the 30th anniversary of the first CITIZEN radio-controlled watch we are debuting the world’s first fully analogue moon phase function for light-powered watches. The Tsuki-yomi collection (directly translating to “reading the moon”) features a new radio-controlled Eco-Drive Cal. H874 movement that provides ±15 seconds accuracy per month, revolutionary proprietary Super Titanium™ material and artfully crafted moon pattern dials. Based on a unique mathematical formula developed by CITIZEN called “Luna Program”, the watch calculates the phase of the moon each day from signals received from multi-band radio transmitters. The phase of the moon at the six o’clock position is then automatically adjusted and displayed. With a striking red pattern of the moon’s surface on the dial paired with a black outer ring, and date display at the 4 o’clock position. Sustainably powered by any light, including moon light, with our proprietary Eco-Drive technology, this timepiece never needs a battery.\u003c\/p\u003e","brand":"Archive","offers":[{"title":"Default Title","offer_id":45779623411869,"sku":"CZ-749","price":582.5,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0193\/3758\/files\/cz-749-citizen-watch-tsuki-yomi-radio-controlled-moon-phase-by1018-55x_9683ccdb-848b-4359-8ac2-a5747efc61d0.jpg?v=1732715934","url":"https:\/\/whamond.com\/en-us\/products\/citizen-watch-tsuki-yomi-radio-controlled-moon-phase-by1018-55x","provider":"W Hamond - The Original Whitby Jet Store Est.1860","version":"1.0","type":"link"}
