This field guide project explores the evolution of wristwatches through a three-booklet series, designed to inform readers about their timeline and historical significance. Inspired by the visual language of blueprints, the identity features a blue-and-white color scheme, accented with bright yellow to add visual interest and energy. Each booklet uses a distinct layout grid system to establish a unique identity while maintaining overall cohesion. The final identity includes three booklets that blend technical precision with engaging, accessible design.
