Clock24h

Clock24h turns the watch into 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. Clock24h 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. THREE COLOUR SCHEMES Mies — white day, black night, one red marker. Corbu — warm amber day, slate blue night. Pesce — bright red day, bright blue night, yellow badges. 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. COMPLICATIONS Ring — the day/night ring on its own. Ring + Time — the ring with the current time inside it. Mini Dial — the whole 24-hour dial, shrunk. KEEPING THE DIAL UP Clock24h supports the always-on display. Leave it open and the dial stays up, dimmed, refreshing once a minute. To keep it up for longer, open the Watch app on iPhone, go to General, then Return to Clock, find Clock24h in the list, and choose a longer interval. Raise your wrist and the 24-hour dial is what you see. DETAILS The second hand ticks once a second, sixty steps to the turn. A smooth sweep is available in settings if you prefer it. Sunrise and sunset are worked out on the watch from your location. Nothing is sent anywhere.

Verdict
The clearest difference is in-app purchases: Clock24h at none against Disk Decipher's 8. Clock24h also leads on iOS requirement (15.0 vs 17.0). Disk Decipher's advantage is update cadence (weekly vs every 6 weeks) and chart position (#47 vs unranked). On ads and device support there is nothing between them.
