Aventurine Open-Heart Watch

Aventurine Open-Heart Watch – In-House Movement with Visible Balance Wheel

The Aventurine Open-Heart Watch brings together a starry dial and our own in-house mechanical movement in a design that’s clean, reliable, and a little special.

The dial is made from genuine blue goldstone aventurine glass — deep navy with thousands of tiny copper flecks that catch light and sparkle like stars in the night sky. The surface has a subtle, three-dimensional glow that shifts gently when you move your wrist — quiet depth without being flashy.

At 6 o’clock, an open-heart window shows the balance wheel beating steadily. This is the heart of our self-developed automatic movement — visible proof of the mechanical action that keeps the watch running smoothly day after day.

The movement is fully designed and assembled in our factory. It runs at 28,800 vph for smooth seconds, holds a solid power reserve, and delivers consistent accuracy with everyday wear. We focused on reliability and simplicity so the watch feels dependable and easy to maintain.

The case is solid 316L stainless steel with brushed sides and a polished bezel — it looks sharp but handles real life without showing every mark. It comes with a black leather strap that’s comfortable from the start and wears in naturally over time.
