The Great Oak Dial - Ice Blue (GMT) [For NH34]

The Great Oak is a “Grande Tapisserie” guilloché dial — a dense pyramid-grid pattern machined into the surface in two levels, not printed on top. The two depths catch light at different angles, so the face throws a shifting sunburst as the wrist moves. It’s finished in a cool ice blue, and each blank is CNC-embossed over roughly an hour before it’s decorated. The hour markers are polished-silver applied (raised) indices filled with 100% Swiss Super-LumiNova® BGW9 Grade A — white by day, a cool ice-blue glow by night. It’s an oblique homage to the iconic octagonal integrated-sport dial, reimagined at the 28.5mm Seiko mod standard.

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.

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.

Yes — the applied indices are filled with 100% Swiss Super-LumiNova® BGW9 Grade A: a cool blue glow by night, white by day, lasting up to eight hours on a full charge. For maximum glow, pair it with hands that also carry BGW9 so the whole face glows together (hands are sold separately).

This is a GMT layout, so it needs the Seiko NH34 — and only the NH34. The dial uses the wider 2.7mm centre hole the NH34's 24-hour GMT pinion passes through. It will physically sit on an NH35 or NH36, but a standard hour hand often won't cover the wider bore, so the movement shows through — for a clean result, use the NH34.

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.

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.

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.

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.

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.
