Esterbrook x Accutron Fountain Pen | Spaceview

In 1960, the Accutron Spaceview watch changed the way we look at timepieces—exposing the movement and making it the center of the design. The latest Esterbrook x Accutron collaboration brings that same idea to a fountain pen: a transparent demonstrator where the construction is visible from every angle.

The Spaceview Estie is the first transparent demonstrator pen in Esterbrook's history. The polished acrylic cap and barrel reveal the threads, connectors, filling system, and internal components of the writing mechanism—usually hidden from view. An Accutron green acrylic grip section echoes the signature color of the Spaceview watch, complemented by bronze finials and gold-plated details visible through the transparent barrel.

The Accutron tuning fork emblem appears in several places: as a lacquered logo on the top finial of the cap, on the custom cap ring, and on the gold-plated nib.

• Cap closure system: Esterbrook cushion-cap system
• Filling system: universal cartridges and converter (both visible through the transparent barrel)

About the demonstrator

• A demonstrator is a pen with a transparent or translucent body, allowing you to see the internal components
• Originally used by manufacturers to showcase filling systems and mechanics—today, they are prized by collectors for the visibility of their construction
• The interchangeable nib system allows for easy personalization: changing the size and type of nib without tools
