Graduated from the watchmaking school of Paris in 1981, Vianney Halter spent the first ten years of his professional life with the restoration of old clocks, pocket- and wristwatches. This enabled him to acquire a broad knowledge of horology. Independent since 1994, he imagined and realized various timepieces for famous brands. Strong of this background, he realizes his own watch in 1998, the Antiqua. This perpetual calendar has been presented at the Basle Fair in 1998 at the AHCI boot, which he is member of since 2000.
