Clocks are one of the oldest design playgrounds, and yet most of us still live with the same two-hand layout we grew up with. Designers keep trying to find new ways to visualize time, sometimes at the cost of instant readability. The Trace Line Clock is a small desk piece that connects hours and minutes with a single, constantly changing line, turning the familiar dial into something that feels a little more like a drawing.

The Trace Line Clock is a minimal, 3D-printed desk clock by Hye-jin Park that uses one continuous hand to show both hours and minutes. The inner end of the line rides an inner circle for the hour, while the outer end rides an outer circle for the minute. As time passes, the line’s angle and length shift, so every glance shows a new geometric relationship between the two.

Designer: Hye-jin Park

The physical form is a white, wedge-like block that leans back slightly, with a circular recess on the front. Two concentric tracks are cut into that circle, and a single colored line spans between them. There are no numerals, logos, or extra markings, just the circles and the hand. It reads more like a small piece of graphic sculpture than a typical clock, especially on a clean desk.

The inner tip of the line points to the hour on the inner track, while the outer tip points to the minute on the outer track. It’s not as instant as glancing at a bold wall clock, but it’s also not inscrutable. With a moment’s attention, you can read it reasonably well, and the payoff is that you also get a little geometric drawing that changes every minute instead of just numbers.

Because the minute end moves faster than the hour end, the line is always stretching, shrinking, and rotating. The clock doesn’t just tick; it sketches. Checking the time becomes a small moment of noticing how the hand has reconfigured itself, not just a quick number grab. It’s the kind of object that rewards a second look rather than a drive-by glance at your phone or wrist.

The clock hides a standard movement and two internal hands behind the face, using magnets to couple them to the visible line. The front stays clean and uninterrupted, with the hand floating in the recess. The choice of a single accent color for the line against the white body keeps the focus on the changing geometry, not on branding or ornament that would clutter the composition.

The Trace Line Clock is not the tool you buy if you need to read the time from across the room in half a second. It’s a small, thoughtful piece for a desk or shelf where you don’t mind spending an extra beat to parse it. In return, it turns time into a quiet, evolving graphic that feels more like a living diagram than a static display.
