A literary clock. Every five minutes, a passage from a book that names the time, with the time itself lit.

"You just let me have all your plans and sections, drawings and the rest of your fixings in time to catch the ten o'clock train to Pittsburg."

More than six hundred passages from classic novels, each chosen to fit your watch's screen, and a different one each morning and evening. The author and title sit below the passage and the time in figures above it. Round the edge runs a chapter ring, a mark for each minute with the minute now lit.

Black on white by day and white on black by night, or keep to one. The settings also turn off the figures and the ring.

Find out how fast or slow your mechanical watch runs. Wear it on one wrist and your Pebble on the other, and when its seconds hand reaches 12, press SELECT. Regulator times the press against the Pebble's phone-synced clock, asks which minute your watch showed, and keeps the offset.

Over a few days of checks it works out the rate in seconds per day, shows it on a regulator scale with the chronometer tolerance (-4 to +6 s/day) marked, and charts the run like a timegrapher. Two checks at least four hours apart give a first rate, marked provisional until the checks span a day.

"I just set it" starts a new run after you set the watch, and "Undo last check" takes back a slip. Keeps a separate record for up to four watches, named in the app's settings. The checks are kept on the Pebble.

A 24-hour astronomical watchface. The dial runs from midnight at the bottom to noon at the top, and its ring is coloured for today's day, twilight and night where you are, with a line along it while the moon is up. The sun's marker travels round the ring through the day.

Inside the ring, a pixel-art landscape under the sky as it is right now: blue by day, golden and then banded at sunset, twilight, then night with stars. The sun and moon stand at their real height and set behind the hills at the real minute, and the moon shows its phase the right way round for your hemisphere.

Below the hills: today's sunrise and sunset, the length of the day, and the moon's phase.

Everything is worked out on the watch, from NOAA's solar equations and a lunar theory, so midnight sun and polar night come out right.

Where you are: your phone's location, read at most once a day, or a latitude and longitude typed into the watchface's settings. 12 or 24 hours follows the watch.

A small creature lives on this watchface, under the time, and gets on with its day. Choose one of five:

- The raven hoards shiny things, now and then carries off a digit of the clock to sit on, and takes offence when you only look to check the time.
- The clockwork beetle winds its own key, polishes the digits and stamps the hour in.
- The cat sits in its box, hunts a toy mouse and pushes digits off the clock.
- The moth circles its lantern, takes the colon for a light and eats the date.
- The slime changes colour by the hour, splits in two and tries to be a digit.

It moves for a few seconds when the minute turns and when you flick your wrist to look, sleeps at the hours you set, and dreams. What it does comes from the time alone, so there is nothing to feed and nothing to lose, and the time stays readable throughout.

In the watchface's settings: the creature, the date on or off, its bedtime and the hour it wakes. 12 or 24 hours follows the watch.

The time in words, the way you'd say it: "twenty to nine", "quarter past eleven". FuzzyWatch rounds to the nearest five minutes and sets the phrase in up to three lines centred on the round screen, the hour in large type, with the date below.

When the words change, the lines that changed dissolve into scrambled letters and resolve back, left to right, one line after another.

Eight personalities, chosen in the watchface's settings:
- Spoken: "twenty to nine"
- Classic: "just after nine am"
- Shakespeare: "'tis half past three of the clock"
- German: "fünf vor halb zehn"
- Mission Control: "T-10 MINUTES, 1400 HOURS"
- Eldritch: "the stars are right, the twelfth hour"
- Latin: "viginti quinque ante hora XI a.m."
- Vague: only the part of the day, "after lunch"

The German and Latin styles write the date in their own language too. The date can be turned off. The face wakes once a minute and draws only when the words change.
