HZ.03 Blue Marble - Aventurine

The HZ.03 is a reflection of time and perspective, inspired by the first full portrait of Earth captured in 1972 -The Blue Marble. Beneath its domed sapphire crystal, an orbiting Earth on the seconds sub-dial traces a steady path around the dial, mirroring our planet’s orbit in space.

Machined from grade 5 titanium, the 36mm case is lightweight and enduring, housing a precise Seiko VD78 quartz movement.

Available in enamel lacquer and aventurine dials, each variant offers a distinct play of light; from the deep shimmer of the stars to the clarity of daylight on Earth.

Compact, durable, and effortlessly wearable, the HZ.03 brings cosmic perspective to the wrist; a reminder that every second is part of something greater.
