Thank you for viewing. This is a Casio F-91W series watch. It's commonly known as the "Bin Laden model." It's a product that boasts three key features: durability, accuracy, and affordability. There's even a story that one was buried underground for 20 years and still functioned with only a 7-minute time difference. This one is a rare skeleton color (light blue). Although listed as a men's watch, it's unisex. For those who need it, please consider. Unopened. Will be sent via anonymous postal service (post-in). Please be aware of this beforehand.
