Jaquet Droz is honoring the day of love with a new Petite Heure Minute which has a dial made of cuprite. The watch will be limited to only 28 pieces. Each dial will look unique as the stone never looks the same. This is a wonderful horological creation with cuprite, a precious stone which was first found in the middle of the 19th century. This mineral is very difficult to treat and work with as it easily breaks. The hour and minute hand are made of mother of pearl. The case is made of 18 carat rosegold. This is a treasure reflecting passion, love and emotion.
