Chronomade

An enlarged flywheel at its core—drawing inspiration from mechanical time itself—turns energy into rhythm within a phone case.

Infuse Energy

Rotate the ridged ring around the MagSafe circle to wind the mainspring, storing energy within the mechanism.

Feel Heartbeat

Flick the lever. Release the flywheel. Experience every heartbeat.

MagSafe-Ready

We love the convenience MagSafe brings. That’s why we use a high-carbon iron composite steel to recreate a precise, reliable magnetic attachment—making it a breeze to grab your phone and go.

Note: MagSafe wireless charging isn’t supported, keeping the precision mechanism safe and perfectly tuned.
