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 grey 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":"Citizen","offers":[{"title":"Default Title","offer_id":52590944354570,"sku":"BY1010-57H","price":699.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0926\/5276\/5450\/files\/citizen-mens-tsuki-yomi-radio-controlled-moon-phase-watch-p50372-93296_image.jpg?v=1781656532","url":"https:\/\/www.francisandgaye.co.uk\/products\/citizen-mens-tsuki-yomi-radio-controlled-moon-phase-watch-by1010-57h","provider":"Francis \u0026 Gaye","version":"1.0","type":"link"}
