【Surfing & Fishing】CASIO G-SHOCK GULFMASTER Pepsi Wristwatch It's working and the operation has been confirmed. The backlight also works perfectly. This is the Gulfmaster Pepsi model. It has many functions such as tide graph, moon age, compass, and thermometer. Perfect for outdoor activities, and with its tide graph function, it's great for surfing, fishing, and marine sports. I think it has little wear, scratches, and minor imperfections. Comes with a box and instruction manual.
