The visionary
behind the machine.

One person who could never find the watch he wanted — so he made it.

What's on your wrist
matters.

"There's a moment between every tick when nothing happens. That's the moment I've been chasing my whole life."

When I was a kid, my grandfather wore a watch he never set down. I was fascinated by it — but not for the reason you'd think. I was fascinated by the seconds in between: the gap between one tick and the next, the space where time is but nothing happens. Most people look at a watch to see the hour. I looked at one to see everything else.

I joined the military on a coin flip — it was between that and film school. In boot camp I broke my Fossil on the butt of my gun during training, and chose not to replace it. I liked the idea of keeping a reminder of the exact time my watch died.

I built Mercier Prototype because that fascination never left. I could never find a watch that was exactly what I wanted — so I decided to make them.

Every Mercier is designed by me. Each case is serial-numbered. Each component is thoughtfully sourced for one reason: to do its job, and then a little more. There is no heritage premium. There is no boutique markup. There is the watch, the math behind it, and the person who made it.

That's the watch. That's the whole story.
