Here the current Moon phase is shown with more convenience for observers of southern hemisphere.

If holding the Pebble watch parallel over ground and turning it so the hour hand is pointing towards the sun then top of the watch face will always point in north direction and bottom of watch face in south direction on southern hemisphere (Compass feature).

Mind the observer's orientation and location: The compass feature is basically depending on the user's (or better the observer's) orientation and position on Earth - respectively the latitude of the observing position. At higher latitudes the compass feature is easier to use and more fail safe. The Earth's orbital plane around the sun projected onto the celestial sphere is called ecliptic. The Earth's equatorial plane projected onto the celestial sphere is called celestial equator. The ecliptic and the celestial equator are oblique by an angle of approximately 23.5 degrees currently. This means that an observer standing at any position close to the Earth's equator will lack a preferred view during noon (close to standing directly perpendicular under the sun called the sun is in observer's zenith) to point the hour hand towards the sun holding the watch parallel over ground. Meaning the compass feature is either not working at observer positions with smaller latitudes or the compass feature is at least hard to apply.

Mind the difference of southern hemisphere and northern hemisphere: On northern hemisphere top of the watch face will indicate south direction while bottom of watch face is oriented north.

Additionally the current Moon phase is shown for southern hemisphere. Moon phase display is expected to work until end of Unix Time (overflow on Jan 19th, 2038 03:14:07 GMT) at least as implemented here. For simplicity the axis of the Moon is shown vertically on the watch face only.

Mind that observer will have a preferred viewing direction: The Moon's view on the sky might vary from upright vertical orientation being rotated by a certain amount of degrees depending on observer's latitude and the current position of the sun. Regarding the observer's location/latitude it shows itself close to upside down between both hemispheres in direct comparison. The inclination of the Moon's orbital plane towards the plane of the Earth's equator has an angle of approximately 5 degrees. For simplicity assume that the Moon's orbital plane equals the plane of the Earth's equator neglecting the about 5 degrees angle. Such that on northern hemisphere the Moon will always appear in south direction with an observer usually and conveniently looking southward. On southern hemisphere vice versa just the other way around. Due to symmetry reason with an observer being near equator there is less preference or convenience for choosing a observation direction. The orientation of the crescent Moon can simlpy be swapped by an upwards looking observer turning towards opposite direction then.

Anyway the Moon's crescent always points towards the sun.
