Collection ofthe Stars

Astronomical watchmaking expressed through celestial displays, distinctive materials and different ways of reading the sky.

Astronomy,Seen Differently

The Collection of the Stars explores astronomy through a wider range of mechanical indications and design. A rotating planisphere follows the stars above the Northern Hemisphere, moon phases track the changing lunar cycle, while chronographs and calendar indications introduce another way of measuring time.

Across the collection, these complications are combined with materials and finishes that reinforce their celestial character. Aventurine, meteorite, sapphire and carefully considered colour bring depth to the watches without losing sight of the mechanics beneath them.

Ariadne

Ariadne brings together a chronograph, complete calendar, 24-hour indication and moon phase within a 40 mm case. Across its different interpretations, changing dial materials and finishes give the familiar complication a remarkably different character.

Lady Orion

The Lady Orion brings the celestial design language of CVDK to a more compact 32 mm format. Aventurine and meteorite dials place natural and celestial materials at the centre of the design, with selected references complemented by diamond detailing.

More Than OneWay to Read the Sky

Astronomy is not expressed through a single complication. The Orion maps the stars as the Earth turns beneath them, while the Ariadne and Hypernova follow the changing appearance of the Moon alongside the familiar measurements of a chronograph and calendar.

Together, these different displays show how celestial time can become part of a mechanical watch without every model speaking the same visual or technical language.

Materials with aCelestial Character

The identity of the collection also comes from its surfaces. Aventurine evokes the irregular depth of a star-filled sky, meteorite introduces material formed far beyond Earth, while transparent sapphire reveals layers normally hidden beneath the dial.

Used with restraint, these materials become part of the astronomical expression of the watch rather than decoration added around it.

Across theCollection

Celestial displays, unusual materials and mechanical details give each model its own interpretation of astronomical watchmaking.
