SEIKO セイコー KINETIC AUTO RELAY キネティック オートリレー Movement The built-in rotor rotates and generates/charges power when the watch is shaken. The main feature is that if the watch is not moved for a long time, the hands stop and enter power save (sleep) mode, but when the watch is shaken again, the hands automatically fast forward to the internally memorized current time and resume. While maintaining the high accuracy of quartz, it has a driving capacity of about 4 years (in power save mode) when fully charged. 【Model Number】5J22-0D50 【Color】Silver, Black Dial 【Size】 Case: Approximately 3.5cm (height) Approximately 4cm (width, including crown) Wrist circumference: Approximately 19cm 【Condition】 Operation confirmed.
