Part of the Moritz Grossmann Chinese Zodiac Collection created exclusively for Christie’s online auction, this one-off piece made from stainless steel features hand-painted dial with a miniature drawing according to the artistic design of Tony Käseberg. Including original painting of the artist.
The side view of the ox shows off the animal in all its glory. With his sketch style, the artist breaks up the familiar grid of a detailed drawing and gives the motif a ‘wild’ touch. The increasingly intense colour gradient shows the tonicity of the ox, which increases from the legs to the horns.
In line with its second position in the Chinese zodiac, the ox’s self-confident gaze is directed towards 2 o’clock. The ox is very hard-working, reliable, ambitious and determined. Oxes are extremely honest and sincere. Oxes work tenaciously and with a lot of patience until they reach their goal. But first they have to draw up an exact plan. The polished stainless steel hands, handcrafted in the manufactory, harmonise with the solid silver dial.
Years of birth under the sign of the ox: 1937, 1949, 1961, 1973, 1985, 1997, 2009, 2021
Name of the artist: Tony Käseberg
The artistically finished calibre 100.1 movement is visible though the generous transparent back made of sapphire crystal with an antireflective coating on one side. The pillar movement with well-proportioned components made of untreated German silver with various finishes forms different levels.
On the characteristic 2/3 plate with broad horizontal ribbing, the signet is engraved by hand. The Grossmann balance is visible in the curved plate cut-out and is borne by the stepped, hand-engraved balance cock with the typical fine micrometer screw.
