Célestin Astronomical Moon 40

Precise moon phase, off by one day only after 122 years.

Ordinary moon phases drift by a day every two and a half years, this one only after 122 years. The gold moon sits in front of aventurine glass, where small copper crystals glitter like stars.

Célestin Carte du Ciel 42

Star chart of the northern sky that turns with sidereal time.

A sapphire disc with 600 stars turns once a sidereal day, about four minutes shorter than a solar day. A window shows which sky is above Lake Geneva right now.

Célestin Équinoxe 40

Equation of time with an annual ring and hints of sunrise and sunset.

A ring at the edge shows the whole year with equinoxes and solstices; a sun hand points to how far solar time differs from clock time today. For people who like to know why noon is not always at twelve.

Célestin Jour et Nuit 40

Day-night display with sun and moon in a semicircular window.

Through a semicircular window a gold sun passes by day and a moon among stars by night. A gentle complication with nothing to work out: you see at a glance whether it is 8 in the morning or evening.

Célestin Lune 36 Aventurine

Small moon phase watch on aventurine that sparkles like a starry sky.

The dial is aventurine glass in which tiny copper crystals sparkle like stars. A mother-of-pearl moon crosses it; only hours and minutes, so nothing distracts from the sky.

Versions: 18k white gold and 18k rose gold

Célestin Lune Australe 39

Moon phase for the southern hemisphere, with the Southern Cross on the dial.

In the southern hemisphere the moon waxes from left to right, mirror-image to the north. This watch shows it as you see it in Sydney or Cape Town. The brand's only steel case.

Célestin Marées 41

Tide display with moon phase and spring tide indication.

From the positions of moon and sun the watch shows high tide, low tide and spring tides. It is set once for a harbour; on other coasts the display shifts by a few hours.

Célestin Planétaire 42

An orrery on the wrist: six planets circle the sun in real time.

Mercury takes 88 days for a lap, Saturn almost 30 years: the movement follows the real orbital periods, and the planets are cut from stones such as lapis lazuli and carnelian. Twelve pieces.

Célestin Quantième Lunaire Perpétuel 41

Perpetual calendar with an astronomical moon phase accurate for 577 years.

The moon train is geared so precisely that it drifts one day only after 577 years; the calendar counts leap years until 2100. Together they make this the workshop's favourite piece.

Célestin Temps Sidéral 41

Shows solar and sidereal time side by side, for stargazers.

The stars rise about four minutes earlier each day; astronomers therefore work in sidereal time. The watch shows both, so there is no converting at the telescope.

Price: €74,000

Célestin Tourbillon Céleste 42

Tourbillon beneath a rotating star chart of the northern sky.

Above, the star chart turns once per sidereal day; below, the tourbillon cage once a minute. Two rhythms you can see: the sky and the heart of the watch.
