WHAT AN OPEN-HEART IS
An open-heart watch features a cutout in the dial — usually at 6 or 12 o'clock — that exposes the balance wheel of the movement beneath. Every oscillation is visible. You're watching the watch keep time in real time.
It's a complication in the horological sense — an additional feature beyond simple time display. But unlike a chronograph or moon phase, the open-heart requires no extra mechanism. It's the movement itself, made visible.
THE NH70 MOVEMENT
Valusis open-heart models run on the Seiko NH70 — a 21-jewel Japanese automatic movement. It beats at 21,600 vibrations per hour. Through the aperture, you can count the oscillations: the balance wheel completes three full swings per second.
The NH70 was designed with display in mind. Its finishing — the perlage on the plates, the bevelled edges on the bridges — is visible quality. It's not decorative. It's proof of engineering.
THE PHILOSOPHY
Other brands at this price point hide cheap movements behind solid dials. The open-heart configuration is a statement of confidence: the movement is worth looking at. We want you to see it.
Valusis open-heart models are available in black, brown, and silver dial variants. Each shares the same movement, same case, same 10ATM water resistance. The difference is aesthetic.
WEARING MECHANICAL ART
A watch with a visible balance wheel changes the way you think about time. You don't just check it — you watch it. The oscillation is constant, patient, precise. That's what you're carrying on your wrist.
No extra markup for the complication. Same honest price. The movement does the work — you just have to look.
