Gold color case with brown leather. At 6 o’clock, the dial opens completely to reveal the co-axial tourbillon cage.

The oversized Arabic numerals (11, 12, 1, 3, 5, 9) are thick, applied elements in a brushed blue tone.

The exhibition caseback offers the clearest view of the movement’s mechanical logic. The two mainspring barrels are positioned symmetrically, flanking the gear train and transmitting energy forward to the escapement.

About St. Moritz Tourbillon

At 6 o’clock, the co-axial tourbillon dominates the visual field. The cage rotates continuously, carrying the balance and escapement in a gravity-neutralizing orbit. The cage architecture is multi-armed and polished, with thermally blued screws securing its structure.

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

Brushed wheels, polished screw heads, and cut-away structural bridges designed for structural clarity rather than ornamental excess. The caseback sapphire reveals the gear train in full, including not one but two barrels and transmission wheels, arranged in layered depth.

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 excellent standards of manufacture, production, and style motivate the Theorema'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.
