KRONOS 24h

KRONOS 24h is a 24-hour dial. One full rotation is one full day: midnight at the bottom, noon at the top. A glance tells you where you stand in the day, not just in the hour. The dial is filled in with real daylight. KRONOS 24h computes sunrise and sunset for your location and paints daylight as the bright region, night as the dark one. The seam between them drifts through the year. Far north or far south, where the sun no longer sets or no longer rises, the dial simply turns to all day or all night. TWELVE COLOUR SCHEMES Mies — white day, black night, one red marker. The original face. Corbu — warm amber day, slate blue night, red cardinal badges, stencil numerals. Sigvaldi — yellow day, deep blue night, white marks throughout. G.Pesce — red day, blue night, yellow badges. The rim and the seam leave strict geometry, the way poured resin never quite closes on a circle. Árni Kím — amber day, indigo night. Every mark takes the opposite of the half it sits on. Högna — linen day, grey night, one dark ink for every mark. After Högna Sigurðardóttir. Gunta — madder rose day, deep green night, ochre only at night. After Gunta Stölzl. Marianne — nickel silver day, ebony night, a brass second hand and moon. After Marianne Brandt. Lilly — orange velvet day, black velvet night, gold-silk marks, a silver moon. After Lilly Reich. Lina — light blue day, deep blue night, red by day, garden green by night, a yellow moon. After Lina Bo Bardi. Charlotte — dusty blue day, black night, ivory badges, a rose moon. After Charlotte Perriand. Aalto — light brown day, black night, black and ivory only, stencil numerals, an ivory moon. After Alvar Aalto. The last seven carry the moon: a disc at the centre whose lit part follows the real phase, turned the way the moon looks from where you stand. Tap the dial to choose. Each row in the list is painted in its own scheme, so you pick by looking rather than by reading. CLOSE-UP Turn on Close-up in settings and the centre of the dial fills the screen — the moon, the seam and the hands, nothing else — with the time in small stencil figures in the corner. It works with every scheme. THE DIAL AS A WIDGET 24-Hour Dial brings the same face to the Home Screen on iPhone and iPad, and to Notification Centre on the Mac, in four sizes. It keeps the scheme and the location you chose in the app, and moves on once a minute. ON THE MAC The Mac app runs the same dial full screen, and its widget sits alongside your other desktop widgets.
