Titanium or Tremblage…the New Versions of the Moritz Grossmann Tourbillon

Moritz Grossmann continues to explain its vision of watchmaking from Glashütte with two new interpretations of its most complex watch, the Tourbillon Titanium and the Tourbillon Tremblage. These two new versions are mechanically identical to the original model, introduced initially in 2013 when the Grossmann calibre 103.0 established the brand’s first in-house tourbillon, notable for its three-minute rotation and flying architecture inspired by Alfred Helwig. Still, the new versions reinterpret its classic Glashütte form through contrasting materials and textures, one emphasising modernity and lightness, the other artisanal depth and traditional engraving. 

The new Tourbillon Titanium comes in a three-part case measuring 44.5mm in diameter and 13.9mm in thickness, featuring a slim bezel and a softly darkened metallic sheen. The solid silver dial is decorated with a fine grain d’orge guilloché pattern, cut by hand on historical rose engines. Its off-centred hour and seconds sub-dials are recessed, framing the large aperture at 6 o’clock where the flying tourbillon rotates once every three minutes. All typography and scales are printed in black, while the in-house hands are manually crafted and annealed to a brown-violet hue.

The Tourbillon Tremblage is presented in an 18k white gold case, housing a salmon-toned solid silver dial finished with the historic tremblage technique, where a burin is guided by hand across the surface in trembling motions to create a soft, matte grain. White-printed Arabic numerals, minute scales, and the 19th-century “M. Grossmann” cartouche complement the texture, while the polished steel hands add contrast and legibility.

The dials retain the signature regulator-style display with central minutes, small seconds at 9 o’clock, and off-centre hours at 3, designed around the large flying tourbillon at 6 o’clock. The tourbillon interrupts the lower minute scale, so the long minute hand extends beyond the central axis to read minutes 25–35 on a separate semicircular scale.

Both versions are powered by the manually wound Calibre 103.0, developed and finished in-house. The pillar movement construction uses untreated German silver plates and bridges with wide Glashütte ribbing, polished bevels, and hand engraving on the plate and tourbillon cock. The ratchet wheel carries three-band snailing, and jewels in white sapphire sit in raised gold chatons secured by polished screws. The cage, 16mm in diameter, carries a 14.2mm Grossmann balance oscillating at 18,000 vph with a Nivarox 1 balance spring and a Gustav Gerstenberger terminal curve.

The hand-wound calibre comprises 245 components (186 for the movement and 59 for the cage), including 30 jewels, four of which are set in screwed gold chatons. Power reserve is 72 hours. Patented features include the stop-seconds mechanism, featuring a human-hair brush on the balance rim, and the manual winder with a pusher that separates hand-setting from activation.

The Tourbillon Titanium is delivered on a black alligator strap with white stitching and a titanium butterfly clasp, limited to 12 pieces, priced at EUR 165,700. The Tourbillon Tremblage, limited to 8 pieces, comes on black alligator leather with a white-gold folding clasp and retails for EUR 207,900.
