Nautilus Turquoise Dial (Day Date)

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.

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.

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).

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.

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.

This is a day-date dial, so it needs the Seiko NH36 — and only the NH36, the one caliber that drives both the day and the date. Don't fit an NH35 here: with no day disc to fill the day window, you'd see the bare movement through the cutout — unsightly.

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.
