At the heart of the Sternenhimmel Green lies the hand crafted balance wheel, a defining element of the watch. Each balance is individually made and adjusted by hand, shaping both its precision and its character, and reflecting a level of independence beyond standard industrial solutions. Set against the vibrant depth of the green aventurine dial, the balance is held between two hand engraved bridges, with the front bridge visible from the dial side, creating a clear focal point within the composition.

The bridges are crafted from German silver, chosen for its warm tone and natural depth. Their tremblage finish creates a fine, matte surface that softens reflections and gives the movement a calm presence. This is contrasted by hand polished bevels, which define the edges with sharp clarity. The hand engraved balance bridge adds a final layer of detail, reinforcing the individuality of each piece without disturbing the overall harmony.

The winding system reveals a more technical aspect of the watch. The click mechanism is constructed with a distinct geometry, incorporating wolf tooth gearing to ensure a smooth and controlled transmission of energy. This specific profile improves engagement and reduces resistance during winding. The result is a precise and consistent interaction, where the mechanics can be felt as much as they are understood.
