80's CASIO DATA BANK TIMETABLE Watch Battery replaced, operation confirmed. The light bulb also works perfectly. This is an 80s model. The TIMETABLE is a rare lineup within the DATA BANK series. A fully functional one is valuable. There are signs of use, scratches, and marks. The strap has been replaced with a new one, so it is clean and fresh. The length is also sufficient. The protective film is still attached.
