Your calendar, on your watch face. Calendar lists your next appointments, with their start times, right under the clock, as many as fit your screen. Events come from the calendars already synced in the Pebble mobile app, so there is no account to link, no ICS URL and no separate app to set up.

Nice extras: a big 12-hour clock, the date, the current temperature with today's high and low, and sunrise and sunset. 

This needs "Use experimental plugins" turned on in the Pebble app (Settings > Debug>Use experimental plugins). You cant get the calendar without it!!!!!
