【Citizen】Alarm Date / 4H / Ref. 51301-Y / Made in 1965 / The "Citizen Alarm" was released as the first Japanese-made wristwatch with an alarm function. It was launched in June 1959, earlier than Seiko. This product is the second-generation Citizen Alarm "4H / Four Hand," a high-end model. At the time, it was sold as a high-end watch with 40m water resistance. The large 38mm case and the original black mirror dial create a striking appearance. There is some aging near the center of the dial, but overall, there are no noticeable damages. The exterior shows signs of use appropriate for its age, but it is in good condition without excessive damage or dents. The movement is equipped with a mainspring for the watch and a separate mainspring for the alarm. Wind the alarm mainspring with the crown on the 2 o'clock side, and pull it out to set. When the time comes, the arm strikes a bar on the back cover, producing a loud sound.
