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 an anecdote about one that was buried underground for 20 years and only lost 7 minutes of time. This one is a rare clear color. Listed as a men's watch, but it's unisex. For those who need it, please consider. The box is unopened. It will be sent via anonymous postal service. Please be aware of this beforehand.
