Troposphere Pilot Dial v2 (Date @ 6H)

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 dial's date window sits at 6 o'clock, so it needs the special-order Seiko NH35 Date @ 6H. Two things are set for that position on this movement: the date wheel sits at the 6 o'clock aperture, and the numerals printed on the wheel are oriented to read upright through a 6 o'clock window. No other NH35 will work: a standard NH35's date sits at the 4:30 position with its numerals oriented for that spot, and won't line up under this dial's 6 o'clock window. Same NH35 base movement; the date position and numeral orientation are what differ.
