This is a Casio Overlander. Functionality has been confirmed. The condition is relatively good. A titanium belt is included, but when I took it to a watch shop, they said the part for attaching it was bent and couldn't be attached. I'm a watch novice, so I don't understand it well, but they said it simply couldn't be attached. Regarding functions: Alarm, 10-bar water resistance, Super Illuminator. The main body is made of titanium. The belt is a rubber band that was replaced at a watch shop. Please check the photos for the condition. For those who only want the main body and the included titanium belt, I will send it with a 1000 yen discount. Please let me know if you'd like this. I will discount from the listed price. If you are looking for a sturdy and reliable watch, please take this opportunity.
