A series of just twelve numbered, authenticated pieces: this exceptional watch was designed and developed by Philippe Lebru. At the heart of this improbable project… The fragment of a 4.5 billion-year-old meteorite been cut, polished and machine-finished (in the Jura) to form a watch dial. The additional movement plate, of Franche-Comté manufacture, enables the indication of a big date calendar in the 12 o’clock position and a dual zone with hours and minutes at 6 o’clock. The movement is Swiss-made. The watch comes with a certificate of authenticity and a Besançon Viper stamp which guarantee its chronometric quality.
