Snowflake Dial (Open Heart)

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.

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.

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.

The fine minute markers can be. They're individually applied and extremely small, with a correspondingly tiny adhesive footprint, so they can shift or lift if pressed — handle the dial by its edges and never touch the marker surface. The logo and "Automatic" text are firmly applied and don't lift in normal handling. Because of this delicacy, dials with applied minute markers suit experienced modders.

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.

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.
