Traveler's clock 24

Unlike a 12-hour clock, this watch features a 24-hour dial. Such a design provides significantly greater functionality than the traditional 12-hour format:

the ability to display multiple hands for different time zones,
no risk of confusing day with night in another part of the world,
representation of cardinal directions, including:
-- directions of sunrise and sunset,
-- directions of moonrise and moonset,
-- positions of stars,
-- a compass.

The watch displays a compass if the device has a built-in orientation sensor.
Changing the device's orientation also rotates the sun and moon icons, showing the times they will appear in the indicated direction, which is especially useful for photography.
The short gray hand represents the shadow of the moon (similar to how the hour hand shows the shadow of the sun) in the northern hemisphere.

The watch dial does not position 12:00 at the top but rotates proportionally to the distance from the center of the time zone. The top of the dial indicates midday (solar noon).
This is convenient during long journeys across oceans, as the top of the dial always points to midday, regardless of the set time zone.
When traveling west, the dial shifts left, and when traveling east, it shifts right.
A horizontal arc indicates sunrise and sunset times.
The transition between daylight saving and standard time is intriguing: the hands remain in place, but the dial rotates.

The weather forecast is sourced from http://open-meteo.com and covers the next 24 hours:

temperature (minimum and maximum),
rainfall and snowfall,
dew point (gray),
maximum wind gust strength.

To fetch the forecast for a specific location, the watch transmits the location to https://open-meteo.com approximately once an hour, without including any identifying data.
According to the https://open-meteo.com/en/features#terms declaration, this data is not stored.

Thanks to its design, the 24-hour watch with a rotating dial makes it easier to keep track of time and orientation when traveling between time zones. The top of the dial always indicates midday, providing intuitive usability no matter where you are in the world.
