The Ressence Type 1, launched in 2013, is a watch with no hands or crown in the traditional sense. Its time is shown on a set of small orbiting discs driven by the Ressence Orbital Convex System (ROCS), with the hours and minutes on discs that move over a domed dial, and the time is set through the case back. The case is titanium and the movement is based on an ETA calibre with a Ressence module on top; I did not find reliable official figures for the first model’s dimensions.

The brand was founded in 2010 by the Belgian designer Benoît Mintiens, and the Type 1 was the first model sold under it. The convex dial and the orbiting discs give the watch a very flat, instrument-like look.

Reviewers and collectors admire the Type 1 as one of the most original new watch designs of the 2010s, although its unusual display takes time to read. The Type 1 family remains in production in updated versions.
