TAP TOP-RIGHT FOR CONTROLS · TAP DIAL TO HIDE

Palette ?The muted whole-sky-average model, as on the watch.

Twilight

Warm near horizon — dawn ?How much the pre-dawn warming concentrates at the horizon. At 0 it spreads over the whole dial, as built; raised, the zenith stays cool blue-grey while the dawn horizon keeps its colour. Watch 05:40 in August. off Warm near horizon — dusk ?The same confinement for the evening. 0 is the as-built acceptance look: the dusk warming floods the whole dome. A sine of the hour blends smoothly between the dawn and dusk values across the day. off Warmth follows the sun ?Through twilight the warm light gathers where the sun is, and the opposite sky goes cool and blue — the Belt of Venus and the earth's own shadow. This tilts the warming toward the sun's own hour and away from the anti-solar side, so it rotates clockwise down the dial as the sun sets, and is right at dawn without a second rule. Active only through the twilight band: nothing at midday, nothing in deep night. Not part of the as-built spec — set to 0 to reproduce an acceptance face. 100% Anti-solar cool ?How cool the sky goes directly opposite the sun through twilight. This is where the earth's own shadow rises, with the Belt of Venus above it — in life a desaturated blue-grey rather than a saturated violet, so most of this slider runs below its opening value. Separate from the warm concentration because the two do different jobs. 100% Plateau ceiling ?The warming the plateau receives is the crossfade's progress times whatever the slider above leaves through, and that progress keeps climbing all through dusk — so one fixed value drifts, and what looked right at sunset looks too warm half an hour later. This caps how warm the plateau is ever allowed to get and raises the suppression on its own to hold it there. Off at 0, and it never lowers the slider above, only raises it. off Gradient spread ?Widens the blue → white → warm sequence across the dial. The sun's position never moves; only the palette's altitude mapping stretches.1.00x

Beyond the watch ?Impossible on the Garmin. Turn them off to see the watch face, on to see what the screen affords. Sweep and the ember only move — use Run to watch a whole day pass in seconds.

Sun bloom ?Scales the aureole's whole falloff, so the definite sun, the glow and the long faint tail all move together and the profile still reaches exactly zero at its edge. 0 is off. Past about 150% the core saturates before it falls away and the sun flattens into a disc, which is worth seeing but is not what air does.100% Bloom toward horizon ?At 0 the aureole fades out across the last four degrees before sunset, as built — weakest exactly when a real one is strongest, because low sun means the longest path through air. Raise it and the envelope instead peaks around +2.5° and cuts to nothing only in the final degree, so the glow leans into sunset while the night stays as clean as before. The sun's own body is untouched.off Star field ?Wheel and Dome are both the sky itself: the Yale catalogue to magnitude 4, the five naked-eye planets, and the moon's light (not its face) thinning the faint stars, appearing brightest-first as the sun sinks. WHEEL is the dial's law: everything at its hour angle, Polaris pinned at the centre, the heavens as mechanism. DOME is the window: zenith at the centre, the horizon around the rim — what you see lying on your back. North up, east on the left, as on every looking-up chart; the bezel becomes your horizon. Designed is the v4 texture, kept for comparison.

Star size 100% Planet size ?The wanderers, sized apart from the stars. They carry their own hue and shine steady rather than twinkling, and Saturn wears his ring — which needs roughly 200% before it reads at dial scale. 100% Stars below the horizon ?Off, the horizon is honoured: a star is drawn only while it is truly up, as outside. On, the whole rigid wheel shows — stars currently below the horizon included, slightly dimmed — so the dial reads as the full celestial mechanism turning about the pole. Wheel mode only — in the Dome the sky ends at the horizon, so this has no effect. Crystal reflection Surface grain Sweeping hand Hand only at night ?On: the hand fades out as the sun rises and back in as it sets, on the same 0 to −6° handover the sun uses. Off: the hand is always drawn, as before.

Dial

Ticks Ember to dawn Sunrise / sunset marks ?A checking aid, not a dial feature. Thin marks at the two horizon crossings with their local clock times, so a render can be verified against a published almanac. The object itself shows no times.

Shabbat ?A POSED demonstration layer, not a zmanim implementation. The moments are drawn from this demo's own solar model at the set place and date — they are plausible, not authoritative, and no rounding, elevation, refraction custom or community convention is applied. All four are off by default and none of them touch the face. The three evening marks are told apart by their form, not by their colour: candle lighting carries one point, sunset carries none, and Shabbat ends carries three — the three stars.

Sunset and sunrise lines Digital time in the night ?Sits at a fixed point in the night region of the ring, which is the bottom of the dial at every hour of the day. It does not follow the hand and it does not wait for dark. Candle lighting ?Eighteen minutes before sunset. Drawn with a single point. Shabbat ends ?Forty-two minutes after sunset, the three-stars moment. Customs vary — 42 and 72 minutes are both in use, and this demo poses 42. Drawn with three points.

Acceptance states ?The six states milestone 3 is accepted against. Set one, screenshot it, and compare with the developer's hardware screenshot of the same state.

Export ?Generates the 13 precomputed colour tables the watch build needs, so the perceptual blend never has to run on the device. The tables come from the two ramps alone, so this file is identical no matter what is set on this panel — use Settings below to capture a tuning session.

Settings ?Lists every control that differs from the as-built defaults, then the full state as a one-line code. The code is copied to the clipboard and written to the address bar, so a bookmark restores this exact face. Paste a code back to restore it anywhere.

Reset returns every control to the as-built values — what the spec says the face does today — and clears the code out of the address bar, which is the one way this file can appear to have changed its own defaults. Tuning candidate loads warm 60 / ceiling 20, the values your own two evening observations solve to; it is a candidate, not a decision, and it leaves the time and place alone.
