Hemicube Dial (No Date)

See It On A Watch

LIMITED EDITION · 200 pieces only. Once this run sells out, this dial is retired for good — never remade.

Hemicube Guilloché Dial. Sandblast Ruthenium. No Date.

True guilloché is engraved on a rose-engine lathe by a handful of master craftsmen, and a single dial can run from roughly a thousand to tens of thousands of dollars — the technique is all but monopolised by luxury houses. We wanted that hand-engraved depth without the hand-engraved price.

So we recreated the look of guilloché: a repeating field of three-dimensional cubes — the hemicube — built from a precision sandblast texture that plays with depth, light and shadow. The illusion of carved geometry, at a fraction of the cost.

No logo, no indices, no numerals. Just a pure, illusionary cube field in cool Ruthenium Silver. This is the closed no-date version — a clean cube face from edge to edge.

A numbered run of 200.

A guilloché illusion.
A repeating three-dimensional cube field that reads as carved depth — the look of rose-engine guilloché, reproduced in a precision texture rather than hand-engraved.

Sandblast Ruthenium.
A matte, non-reflective sandblast finish in cool Ruthenium Silver. The lack of gloss is the point — the cubes draw their depth from shadow, shifting as light moves across the dial.

A clean, blank face.
No applied or printed indices, no numerals, no logo, no text. The cube pattern is the entire design; your choice of hands does the timekeeping.

Heads up — a dial is one part of the build

Hands. A dial needs a matching set of hands to tell time. This is a non-lume dial, so it pairs with any set of hands you like — for a night-time glow, choose lumed hands, since the dial itself carries no lume.

Movement. The No Date Hemicube ships with four dial feet and seats on a broad range of 3 o’clock or 4 o’clock calibres — 7S26, 7S36, 4R15, 4R35, 6R15, NE15, NH25, NH26, NH35, NH36, NH38, NH39 — clip the two feet you don’t need. A date or day movement works too; the disc simply hides behind the blank cube face.

Questions, Answered

Everything worth knowing before you build.

Is the Hemicube a real guilloché dial?

No — and we’re upfront about that. True guilloché is cut by hand on a rose-engine lathe, and a single dial can cost anywhere from around a thousand to tens of thousands of dollars, because only a handful of master engravers still do it. The Hemicube reproduces the look of guilloché — a repeating three-dimensional cube field that plays with depth, light and shadow — using a precision sandblast-textured pattern instead. You get the hand-engraved illusion at a tiny fraction of the cost.

What finish and colour is the Hemicube dial?

A sandblast-textured surface in Ruthenium Silver. The sandblast finish is matte and non-reflective, which is exactly what makes the 3D cube pattern read — the depth comes from shadow, not gloss. The ruthenium tone is a cool, gunmetal-leaning silver that shifts subtly as light moves across the cubes.

Does this dial have any markers?

No — it's a fully sterile dial. No applied or printed hour indices, no numerals, no minute track, no logo, and no "Automatic" text — just a clean, uninterrupted surface. Your choice of hands does the timekeeping, and the blank face also makes an ideal base for your own design.

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.

Which movement does this dial need?

This is a no-date dial, so a no-date caliber is cleanest — the NH38 (the NH70, NH71 and NH72 fit too). It also runs on a date caliber like the NH35 or NH36, and on the wider Seiko/TMI family (7S26, 7S36, 4R15, 4R35, 6R15, NE15, NH25, NH26); the date wheel just turns unseen behind the blank dial. In fact, many modders fit an NH35 or NH36 on purpose to future-proof the build — that way they can later swap to a date or day-date dial without changing the movement. One thing to expect if you do: the crown keeps its date-setting position, so you'll feel it click into that detent when you pull the crown partway out — but with no date window, nothing changes on the dial face.

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.

Why does the dial have four legs?

The dial ships with four legs so it fits two different crown positions. Seiko movements come in 3 o'clock and 4 o'clock crown layouts, and the dial feet sit in different places for each. Clip off the two legs that don't match your crown position — two stay, two go.

How do I fit this to a 3 or 4 o'clock crown movement?

Remove the two legs that don't match your movement's crown position by clipping or gently twisting them off, then seat the dial as normal — two legs stay, two go. Alternatively, set the movement's crown to the 3 o'clock or 4 o'clock position, superimpose the dial on top, and see how the feet line up — whichever way it aligns, note which two legs need cutting and proceed from there. See the How To Mod tab for the full fitting walkthrough.

Does this dial work with a normal or an ultra thin chapter ring?

Both our normal and ultra thin chapter rings fit this dial. Where a dial has applied (raised) indices, they sit within the clearance of either ring — so the choice is purely about looks: the ultra thin chapter ring sits low and discreet, while the normal sits a little more pronounced. Pick whichever suits your style.

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.

Customers praised this unique dial for its exceptional quality and captivating light-play effect. "It comes alive" when light shines on it, with appearance changing by angle. Shoppers noted "top notch quality" with no visible flaws under magnification. Many used it in custom watch builds, calling it "the best custom dial" they've seen.

Extraordinary Dial

This is a very special dial. In low light it is relatively dark, but when light shines on it, it comes alive. Its appearance changes with the angle and its captivating just to look at it.

The execution of the dial is as top notch as I’m used to from Lucius. There's not a single flaw visible under a magnifier. It took me some time to find a matching unusual case for this unique dial. I must say, I’m very happy with the result. Thanks for another watch nobody else has but me.

Hemicube Dial Review

I just opened the package and I was amazed at the quality of what I got. I have great plans for a build and this dial is the centerpiece of it. I showed the dial to other people that are into watches and everyone was surprised at the detail and execution. The price to quality ratio ot this product is outstanding.

Hemicube Dial

This is the best custom seiko dial I have ever seen. For reference, other dials I've used in the past include the snowflake dial and the seigaiha dial. This is by far my favorite and I'm very glad I was able to buy it.

Would this work with a NH34 movement (blocking out the date window, obviously)?

Adriel from LuciusAtelier.com

Hello Chris!

Thanks for expressing interest in our mod parts!

>> Would this work with a NH34 movement (blocking out the date window, obviously)?
No, it will not fit. Aside from the lack of date window, the centre hole is too small to fit onto the NH34 movement. NH34 movement requires a much bigger centre hole.

Hope this helps. Let me know if you have anymore questions.

Cheers,
Adriel

Are the dark non-guilloche sides of the hemicubes painted black, or are they silver and it's just the polish that is making them appear black?

Only the parallelogram is inked black. Every where else isn't.
