About Rio

Fully Skeletonized Mechanical Movement. You can see the entire inner mechanism working—gears, balance wheel, escapement—everything displayed through both the front dial and the transparent caseback. No battery. No electronics. Just pure mechanical watchmaking.

Tufina has been an independent family owned watch company since 1828. Theorema Germany hand-sketches and hand-assembles all their watches.

Hand drawing sketch of the collection Rio by Theorema Germany

A perfect fusion of classic and modern look. The Rio uses a traditional mechanical hand-wind movement. Watch enthusiasts love this because it creates a connection between the wearer and the watch.

Mechanism

With attention, planning, and careful execution, hundreds of little parts come together to make each timepiece a scientific marvel, as well as a work of art. One could not mistake the singular modernity of our products - the high standards of manufacture, production, and style motivate the Tufina's aesthetic. From the precision of our sketches, the meticulous detail of our watches, and the quality of our skeletal mechanisms, we’re building our practice on a long-renowned set of engineering standards from this part of Europe.
