Troposphere Pilot Dial v2 (No Date)

It's a modern take on the Flieger Type A (Baumuster A) pilot layout that dates to 1940 — oversized numerals and the characteristic two-dots-and-triangle marker at 12, set inside a printed minute track on a highly glossy black enamel face. The numerals, markers and 12-symbol are filled with 100% Swiss Super-LumiNova® BGW9 Grade A, so the face reads white-cream by day and glows blue at night. The dial is sterile — no logo — keeping it true to the military original.

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.

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 — 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).

Both are premium-grade Swiss Super-LumiNova; the difference is the glow. BGW9 Grade A reads white by day and glows cool ice-blue at night — the modern, crisp choice. C3 Grade X1 reads pale green by day and glows vivid green — the classic tool-watch glow. Both charge fast and glow up to eight hours. Pick by the look you want, and match it to your hands for a cohesive build.

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, 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.

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.
