This is a popular CITIZEN Attesa model, an Eco-Drive radio-controlled watch with a moon phase function. Purchased in Tokyo on August 29, 2024, and only used once. Comes with the box, presentation box, instruction manual, and warranty. The dial, case, and band are all in beautiful condition with no scratches. The band has not been adjusted, but I can adjust the links and ship it after purchase if you contact me. The following is a product description: The watch calculates the moon phase for the day using a unique formula within the movement based on the date information received by radio waves. The moon phase is automatically displayed at the 6 o'clock position. It also features the "NS Shift" function, which allows you to switch between displaying the moon's appearance from the Northern Hemisphere and the Southern Hemisphere. The case shape is sporty yet elegant with flowing lugs. The dial layout is clean despite having multiple hands, and the deep black dial is impressive. *As of August 2023, according to Citizen Watch.
