Meridian: Dual Time Watch Face

Meridian is a dual time zone watch face for Wear OS, with local time large in the centre and UTC (Zulu) or a second zone of your choice directly beneath it. A 24-hour bezel runs round the edge in the style of a flight instrument. It is made for pilots, travellers and anyone who works across time zones.

The second zone is yours to pick. It starts on UTC (Zulu), and you can change it to one of 17 cities from the watch's face editor: London, Paris, Athens, Johannesburg, Dubai, Delhi, Singapore, Tokyo, Sydney, Auckland, Honolulu, Anchorage, Los Angeles, Denver, Chicago, New York or Sao Paulo. Daylight saving is handled by your watch's own time zone data. An amber marker on the bezel shows where that zone's time sits on the 24-hour dial, and a white dot shows local time.

Two complication slots sit under the time. They start as sunrise/sunset and battery, and you can put any complication your watch offers in either one.

Every theme keeps all text at a contrast ratio of at least 7:1 (always-on mode is deliberately dimmer): Night Ops (warm white and amber on black), Cockpit (green on black), Polar (white and ice blue) and Red Line (red, for night flying).

In always-on mode the screen keeps just the local time and the second zone, dimmed, to protect your AMOLED display and your battery.

FEATURES
- 24-hour bezel with quarter-hour ticks and 00-21 numerals
- Large local time (12/24-hour follows your watch)
- Second time zone you choose: UTC or 17 cities, always shown in 24-hour time
- Bezel markers for local time and the second zone
- Day, date and month
- Two complication slots (sunrise/sunset and battery by default, changeable)
- Four themes, all text at 7:1 contrast or higher (always-on mode is deliberately dimmer)
- Always-on mode shows the two times only, dimmed

HOW TO USE
Install on your watch (or from the Play Store on your phone and choose your watch). Touch and hold the current watch face, swipe to Meridian, then tap the pencil icon. Use Theme for colours, Second time zone to pick the zone, and tap a slot to change its complication.

GOOD TO KNOW
- The zone list is fixed. Watch faces cannot take a typed-in zone, so a zone that is not in the list is not available.
- The bezel does not show a daylight arc. Watch faces get no sunrise or sunset data of their own, only what a complication provides as text.
- This is a watch face, not an aviation instrument. Do not rely on it for navigation or flight planning.
- Screenshots show sample complication data.

Requires a round Wear OS 4 or newer watch. This is a Watch Face Format watch face: it contains no code and collects no data.
