With two new interpretations of his most complex watch, the Tourbillon Titanium and the Tourbillon Tremblage, Moritz Grossmann continues to expand on his vision of Glashütte watchmaking. These two new versions are mechanically identical to the original model, first introduced in 2013, when the Grossmann caliber 103.0 established the brand's first in-house tourbillon, distinguished by its three-minute rotation and Alfred Helwig-inspired flying architecture. Nevertheless, the new versions reinterpret the classic Glashütte form through contrasting materials and textures, one emphasizing modernity and lightness, the other emphasizing depth of craftsmanship and traditional engravings.
The new Tourbillon Titanium features a three-piece case measuring 44.5mm in diameter and 13.9mm thick, with a slim bezel and a softly darkened metallic sheen. The solid silver dial is decorated with a fine guilloché pattern in d'orge grain, hand-cut on vintage rose machines. The decentralized subdials for hours and seconds are recessed and frame the large opening at 6 o'clock, in which the flying tourbillon rotates once every three minutes. All fonts and scales are printed in black, while the in-house hands are handcrafted and annealed in a brown-purple hue.
Presented in an 18-karat white gold case, the Tourbillon Tremblage houses a salmon-colored solid silver dial finished using the historic tremblage technique, in which a burin is passed by hand over the surface in trembling motions to create a soft, matte grain. White printed Arabic numerals, minute scales and the 19th century “M. Grossmann” cartouche add texture, while polished steel hands provide contrast and legibility.
The dials retain the characteristic regulator-style display with central minutes, small seconds at 9 o'clock and off-centre hours at 3 o'clock, arranged around the large flying tourbillon at 6 o'clock. The tourbillon interrupts the lower minute scale so that the long minute hand extends beyond the central axis and can read minutes 25-35 on a separate semicircular scale.
Both versions are powered by the hand-wound caliber 103.0, which was developed and completed in-house. The construction of the column work consists of untreated plates and bridges made of nickel silver with wide Glashütte flutes, polished bevels and hand engraving on the plate and the tourbillon cock. The ratchet wheel carries a three-band worm gear, and white sapphire jewels sit in raised gold chatons secured with polished screws. The 16mm diameter cage supports a 14.2mm Grossmann balance wheel that oscillates at 18,000 vibrations per hour, with a Nivarox 1 balance spring and a Gustav Gerstenberger end curve.
The hand-wound caliber consists of 245 components (186 for the movement and 59 for the cage), including 30 jewels, four of which are set in screw-down gold chatons. The power reserve is 72 hours. Patented features include the stop-seconds mechanism with a real hair brush on the balance ring and the manual winding with pusher that separates hand setting from activation.
The Tourbillon Titanium comes with a black alligator leather strap with white stitching and a titanium butterfly clasp, limited to 12 pieces, priced at 165,700 euros. The Tourbillon Tremblage, limited to 8 pieces, is made of black alligator leather with a white gold folding clasp and costs 207,900 euros.
