About
Set your mechanical watch to the second.
Pull the crown. Watch the countdown. The phone taps in your hand at zero, so your eyes never have to leave the dial. No mental arithmetic, no settling for close enough.
Then there are the other four faces. A GMT that tracks a second timezone, a dive bezel you can actually rotate, a chronograph that runs, a moonphase that knows what tonight looks like. Each one comes with a short guide to what the complication does and how to use it — the parts a watch manual assumes you already know.
What's inside
A countdown to the exact second, with a tap in your hand at zero
Five faces: Day-Date, GMT, Moonphase, Dive, Chronograph
Controls that behave like the real thing — pick a second timezone, turn the bezel, run the chronograph
Plain-language guides to every complication, including how to set a date without hurting the movement
A Home Screen widget in the same style, that opens straight to the face you tapped
No account, no analytics, nothing to sign up for.
Go set your watch. Then stop thinking about it.
