+ * DAYS SINCE face (previously Day One)
+ *
+ * This watch face displays the number of days since or until a given date.
+ * It was originally designed to display the number of days you’ve been alive,
+ * but technically it can count up from any date in the 20th century or the
+ * 21st century, so far.
+ *
+ * Long press on the Alarm button to enter customization mode. The text “YR”
+ * will appear, and will allow you to set the year starting from 1959. Press
+ * Alarm repeatedly to advance the year. If your birthday is before 1959,
+ * advance beyond the current year and it will wrap around to 1900.
+ *
+ * Once you have set the year, press Light to set the month (“MO”) and
+ * day (“DA”), advancing the value by pressing Alarm repeatedly.
+ *
+ * Note that at this time, the Day One face does not display the sleep
+ * indicator in sleep mode, which may make the watch appear to be
+ * unresponsive in sleep mode. You can still press the Alarm button to
+ * wake the watch. This UI quirk will be addressed in a future update.
