Design your own 3D watch
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
One of a kind — a watch that's truly yours.
Horogium is an app for designing your own wristwatch. From dial patterns and hand shapes to cases, bezels, and straps, just pick the parts and combine them. No watchmaking knowledge needed — design a photorealistic 3D watch in five minutes.
Recreate the design you've always dreamed of, or try a combination no store has ever sold. "What if that dial had those hands..." — if you love watches, you've had that thought. Now you can bring it to life, right in your hands.
■ Just pick and combine
Guilloché dials, a wide variety of hands, Roman numeral indices, coin edges. Combine the parts, and anyone can build a piece that looks the real deal. Not sure where to start? Let AI mode assemble a first draft for you.
■ Photorealistic 3D
The gleam of metal, the shadows in the dial's engraving, light playing across the crystal — rendered like the real thing. Spin it, tilt it, admire it from every angle. Turn off the light and watch the lume glow in the dark.
■ When it's done, take time to admire it
In viewing mode, savor your watch as the light shifts around it. It becomes a piece you'll keep coming back to, long after you've finished designing.
■ Your watch, on your Home Screen
Place your favorite piece on your Home Screen as a widget. The watch you designed actually keeps time — a one-of-a-kind watch widget.
■ Share and remix via URL
Publish your finished watch as an image and a URL. Anyone who receives it can open the design in the app and rework it into their own. Start from a friend's watch, end up with yours.
Now, go create your ideal watch.
