Stardust Dial v3 - Open Heart

LIMITED EDITION · 300 pieces only. Once this run sells out, this dial is retired for good — never remade.

The Stardust Dial. Glossy Black Enamel. An Open Heart.

A highly glossy black enamel ground scattered with iridescent flecks that catch the light like distant stars across a night sky, with angled, mirror-polished silver applied indices. The Open Heart cutout opens a window onto the movement's escapement — the mechanical heart of the watch, on display.

No two are ever quite alike — the flecks fall differently on every dial, so each piece carries its own constellation.

Part of the Stardust Series.
Limited enamel dials, never restocked. Browse the series .

Glossy black enamel, scattered with starlight.
A deep, highly glossy black enamel ground flecked with iridescent glitter — the celestial signature the Stardust line is known for.

An open heart onto the movement.
A cutout reveals the balance wheel beating beneath — an unobstructed view of the mechanical escapement at work.

Questions, Answered

Everything worth knowing before you build.

Will this dial fit my case?

Yes, almost certainly. This is a standard Seiko mod dial — 28.5mm in diameter and 0.4mm thick, the industry-standard size — so it fits most, if not all, Seiko cases. Where a dial is shown with a particular case, that's an aesthetic pairing, not a fitment requirement. If you're unsure, the surest check is to remove your current dial and measure it with a vernier caliper.

What is an open-heart dial / which movement does it need?

An open-heart dial has an aperture cut into the face to reveal the movement's balance wheel — the beating heart of the watch — through the dial. It's built for the open-heart NH family on a 3 o'clock crown: the Seiko NH38 (the NH70, NH71 and NH72 fit too), whose balance the opening is positioned to frame. Because it's matched to that one family, the dial comes with two feet already in position — nothing to clip.

Are the markers applied or printed?

Applied. The hour markers are applied (raised) indices — raised metal on the dial surface, not flat print. The relief is what gives the face its depth and light play as the wrist moves.

Does this dial have lume?

No — this dial carries no lume. If you want the watch to glow in the dark, pair it with a set of lumed hands; the glow then comes from the hands rather than the dial face.

What's the difference between the Stardust versions?

The Stardust face is shared; the versions differ by complication — Date, No Date, Day-Date (NH36), Open Heart (NH38), and GMT (NH34). Match the version to your movement; the comparison table on each page lays them out.

Can you remove the logo from the dial?

Our dials carry the logo on an adhesive backing rather than a stamped or engraved mark, so it isn't baked into the surface — but removing one cleanly isn't realistic. The adhesive doesn't release without scratching or marking the dial, and the risk is greatest on enamel. We sell our dials as-is and don't modify them. You're welcome to remove it yourself or have a modding specialist do it, just knowing the face will likely pick up some cosmetic marks.

Is this a limited edition / will it be restocked?

Yes, it's a limited edition, and it won't be restocked. Once the run sells out it's retired for good. The edition size is shown on the product page.

Are hands included with this dial?

No — dials and hands are sold separately. This listing is for the dial only; choose a matching handset to complete the build. If your dial is lumed, pairing it with lumed hands in the same lume type keeps the whole face glowing together.
