While Eterna Movement SA started its operation as an independent watch movement manufacturer in 2012, they are rooted in the more than 150 years history of Eterna SA as a watchmaking company. The manufacture of watch movements has always played an important role in the history of Eterna. To begin with the company only manufactured ébauches, however Eterna already revolutionised the automatic movement in 1948 with its invention of the ball-bearing-mounted rotor system. Originally fitted in the Eterna Matic, this watch is now regarded as a benchmark. The use of ball-bearing mountings is de rigueur for Eterna Movement today – a fact also reflected in the depiction of ball bearings in the company logo.

Key milestones and pioneering innovations in the history of Eterna Movement SA to date already include the recently developed ball-bearing-mounted ‘Spherodrive’ barrel design which has set new standards for the quality and durability of a mechanical movement and the calibre 39 family, the unique design of which allows 88 different movement versions to be produced.

As a graphic designer, I'm fascinated by the crossroads between technology and aesthetics. Horology is one of these crafts, where art and engineering come together to produce mechanical wonders that grace the eye. WatchPaper was born from the desire to create an online tool where I can share my passion for watches.
