The Pip-Boy is a wrist-mounted computer device with a bulky, rugged design, featuring a large circular screen surrounded by a metallic casing with visible screws and seams. The screen displays a green monochrome interface, typical of retro-futuristic technology. The device has multiple buttons and dials on the sides, with a weathered and worn texture, suggesting heavy use in post-apocalyptic conditions. The strap is made of thick, durable leather, adjustable to fit various arm sizes, and shows signs of wear and tear.
