In 1960, the Accutron Spaceview changed how people looked at a watch by placing its inner workings at the center of the design. The newest Esterbrook x Accutron collaboration carries that idea into the Estie, creating a transparent writing instrument that allows its construction to be seen from every angle.

The Spaceview is the first transparent demonstrator Estie produced by Esterbrook. Its polished acrylic cap and barrel reveal the threads, connectors, filling system, and internal writing components that are usually concealed. An Accutron green acrylic grip draws from the signature color of the Spaceview watch, complemented by bronze-toned finials and gold-plated metalwork visible through the clear body.

Accutron's tuning fork emblem appears across the pen, including a lacquered emblem set into the top dome, the custom cap band, and the gold-plated fountain pen nib. Esterbrook branding is integrated across the design and packaging, bringing both names together without distracting from the transparent construction.
