Moritz Grossmann HORSE Seven, Unique Piece in Stainless Steel, Chinese Zodiac Collection

Part of Moritz Grossmann’s collection 12 unique pieces exclusively created for the Christie’s online auction, the HORSE Seven is a one-off piece made from stainless steel, and highlights a hand-painted dial with a miniature drawing according to the artistic design of Caroline Kortrijk.

Even as a child, the artist loved to draw horses most of all as she loved their grace and beauty. For her, horses are elegant and powerful, yet good-natured and peaceful. With the wild, smooth application of colour, the artist aims to express the activity and liveliness of the horse. The green colour in the picture and the calla lily in the horse’s mouth are intended to bring happiness to this sign of the zodiac.

The polished stainless steel hands, handcrafted in the manufactory, harmonise with the solid silver dial.

The horse is the seventh of the Chinese zodiac signs.
Years of birth under the sign of the horse: 1942, 1954, 1966, 1978, 1990, 2002, 2014,

Name of the artist: Caroline Kortrijk

The model was manufactured in High Artistic Finish with the calibre 100.1. The 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.
