Citizen Attesa Series LUNA Super Titanium Eco-Drive Solar Power Mens Watch BY1009-64Y. Limited Edition of 2100 pieces globally. Case size 41.5mm with a thickness of 11mm and a lug width of 21mm. Made in Japan.

In collaboration with their corporate partner, ispace inc., three new limited-edition models were created as part of the HAKUTO-R commercial lunar exploration program. Taking inspiration from their ultimate destination, the moon, the BY1009-64Y  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 Citizen 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 2,100 pieces worldwide.

It's been three decades since Citizen introduced the world's inaugural multi-station radio-controlled watch. Now, they're unveiling a limited edition model that evokes the allure of a captivating moonlit and starry night sky. This special edition is based on the H874 movement, featuring the innovative "Luna Program" automatic moon age calculation function.

The dial of the BY1009-64Y showcases a mesmerizing starry sky in black and gold glitter with a gold moon positioned at the 6 o'clock marker representing the moon phase automatically calculated by the Luna program. The two-tone case conjures the image of shining stars against a dark night sky, while the black band and bezel add to the exclusive appeal of this limited edition timepiece.

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. 

A two-tone Super Titanium™ case in two-tone and black DLC anchors the 41.5mm design of the BY1009-64Y. A matching bracelet expands upon the style and secures the watch to the wrist, while a fine mix of polished and brushed surfaces add dynamism to the modern style. Beneath a sapphire crystal, a cosmos-inspired display is on view, with a vertical-configured chronograph, moonphase, and 4 o'clock date window balancing technological utility with intrigue for the eye. Sustainably powered by Citizen’s proprietary Eco-Drive technology to provide light-powered vitality without ever needing a battery. Water resistant up to 100 meters. Caliber H874.

Additional features of the BY1009-64Y include a fold over clasp with push button Super Titanium bracelet, a Perpetual calendar, a power reserve of 2.5 years once fully charged and day & date functionality.
