Christiaan van der Klaauw

Astronomy is the stated focus

Christiaan van der Klaauw says astronomy is the source of inspiration for its watches and describes the business as devoted to designing and producing hand-made astronomical watches. This gives the brand a clear thematic context.

It does not establish the complication set or originality of an individual watch. 1

The official chronology begins in 1974

The atelier says that Van der Klaauw started his own business in 1974 and presented a first clock with astronomical complications. That date belongs to the brand's stated origin story.

Use period documentation when assigning a production period to a particular wristwatch. 1

Current models are named collections

The official collection presentation names the Grand Planetarium Eccentric Manufacture, Planetarium, Real Moon Joure, Real Moon Tides, Real Moon 1980, Titan Perpetual and Venus. These names help distinguish the current families.

A family name alone does not supply a complete technical specification. 1

The atelier locates current work in Naarden

Christiaan van der Klaauw says its mechanical pieces are designed and manufactured at its atelier in Naarden, Netherlands. Treat that as a current official production statement.

It should not be projected automatically onto every earlier example without date-specific evidence. 1

Astronomical claims need reference evidence

The official material associates Planetarium and Real Moon models with specialised astronomical displays. Exact functions, adjustment procedures and operating condition must be confirmed against the watch's own documentation.

Complex mechanisms especially should not be assessed from collection-level language alone. 1

Keep the conclusion source-bounded

The official source supports a 1974 origin and an ongoing astronomical-watch identity. It does not authenticate a watch, prove all-original parts or determine its value.

Use the exact reference, serial information and specialist inspection for consequential decisions. 1

Independent research update

A Dutch astronomical-watch atelier rooted in Christiaan van der Klaauw's 1974 independent workshop; current brand material places production in Naarden.

No independent ownership filing was located in this pass; treat present ownership/control as unresolved.

The 1974 atelier origin and the modern astronomical-watch atelier are presented as a continuing brand story, but corporate-control continuity was not independently established.

Current official material says mechanical pieces are designed and manufactured at the Naarden atelier; exact reference specifications still require model documentation. 23
