Rare Casio G-shock Gq-200 Muscle Time Alarm Clock

Hi Thank you for reading,
Here's a personal collection, one owner item. I had this since mid 90's and it works flawlessly. The residue you see in the pictures are actually not dirty but it's after I cleaned it with soap and dish soap but after set dry, it created a light coated layer. (see pictures for detail) The rubber has no damage and it's in good condition. You can either research on cleaning Casio rubber or paint it with a little DIY project. Functionality, everything works except the center "Time Set" button. Maybe the wire inside is off. so to set the time, you have to insert the batteries at 12 o'clock.(it's a one-time thing or everytime you change the batteries) It takes two AAs. The buttons to set up the alarm works great. Overall, the screen lights up well and the font super readable and the alarm sounds loud and clear. It's a collector's piece and Casio no longer makes this model. An awesome DIY project for the collector.
