The primary challenge was to achieve a truly minimalistic design without sacrificing essential functionality or readability. The difficulty lay in deciding what to remove, not what to add. A watch's purpose is to tell time at a glance, and in a digital format, this requires carefully balancing negative space with legibility. The task was to make the watch feel intuitive and complete, rather than empty or unfinished, all while avoiding a single superfluous pixel or button. The design had to be both a tool and a clean aesthetic statement.
