Citizen Alarm Date Manual Winding Men's Wristwatch, Working Currently working via manual winding. Accuracy over extended periods is unknown. The alarm also functions without issue. This is a Showa-era retro vintage item, but I believe it's in good condition. Please understand that this is a used item that has aged over time. Please be sure to carefully examine the images before purchasing. - Winding the crown at the 4 o'clock position will start the watch. - Winding the crown at the 2 o'clock position and pulling it out, then turning it downwards, allows you to set the alarm. It makes a sound like a cricket. - The calendar can be adjusted by turning the hands. Case: Approximately 42mm (length and width) Lug width: 18mm The bracelet is aftermarket. The wrist circumference is approximately 18cm, but please check the images. (Each notch is 1cm) No box included. As this is a vintage item, we recommend an overhaul if you intend to use it regularly. We appreciate your understanding of used and vintage items.
