I Built a Mechanical Watch Face for Garmin—and Solved a Real Gear Train for a Watch That Has No Gears

I build a mechanical watch face: a real gear train for a watch with no gears

I design mechanical watch faces for Garmin, and people often ask if the wheels are just a picture. They are a picture, but behind them sits a calibre I had to solve like a real one: tooth counts, positions, and a train that actually runs. This is why I bother, and what I learned about making a digital dial that could pass for a watchmaker's work.
