Welcome!! Thank you for viewing. This is a working LUKIA wristwatch. (Ultrasonic cleaning + compound polishing done) It's a very lovely watch. (Brand) SEIKO LUKIA (Face) Approximately 3.5cm (excluding the crown) (Model) 7T92-OAAO (Wrist size) Approximately 15.3cm (Movement) Quartz / Battery-powered (Functions) 3 hands (Accessories) Watch only This product has a chronograph function, so the second hand moves with the stopwatch function. The second hand will be stopped upon arrival, but the watch function is working. It is working properly, so please be aware of this. I do not have the instruction manual, so if you want to use the chronograph function, please purchase it if you know how to use it, or if you can look up how to use it online. Please refrain from purchasing if you are overly concerned about details.
