28 KOHAN UNIQUE PIECE

Created and developed especially with a Finnish collector inspired by his love of his wife for her birthday, the Voutilainen 28 KOHAN Unique Piece embodies the symbiosis of Tatsuo Kitamura’s extraordinary lacquer Japanese artistry, the traditional hand-engraving techniques and enamel with the Voutilainen workshop’s philosophy of longevity, precision and classical watchmaking tradition. This one-of-a-kind piece is a complete work of horological art.

The one-of-a-kind timepiece highlights a mesmerizing case, a distinctive dial made using Urushi lacquering technique along with a movement whose bridges and ratchet wheel are crafted with the same meticulous art, requiring over a thousand hours of work. The raw materials used in this artwork include “Urushi” (tree sap), “Kinpun” (various gold powder), “Kirigane” (cut gold sheets) and ‘Kirigai’ (cut shells from the great green turban and New Zealand abalone).
