This gift box, comprised of the Casio F91 Classic Digital Watch and a Pac-Man co-branded product, is a limited-edition collaboration between Casio and Bandai Namco in 2021. The watch retains the iconic square resin structure of the F91 series, featuring a unibody translucent black matte resin case with four neatly arranged function buttons on the side. The dial is printed with complete PAC-MAN arcade pixel elements, including a yellow Pac-Man outline with colorful ghost patterns in the corners, and displays the co-branded logo and water-resistant chronograph function. The screen can simultaneously display hours, minutes, seconds, day of the week, and date. It houses a quartz digital movement and features a 1/100-second stopwatch, alarm clock, LED backlight, and 10-meter water resistance. The integrated black polyurethane rubber strap is flexible and fits comfortably on the wrist, and the factory-installed battery provides stable power, with all functions functioning flawlessly. It comes with a dedicated black-themed collector's box, featuring a full-page pixelated print of the original 1980s Pac-Man maze, recreating the retro arcade game visuals. The bottom of the box has the original manufacturer's complete model number barcode, and the interior is lined with black flocked padding to secure the watch. It also includes a Japanese original button operation tag.
