After a fresh start in 1983 under JEAN-CLAUDE BIVER, the firm, which was founded in 1735 by JEHAN-JACQUES BLANCPAIN, continues today under the new and equally skilled leadership of CEO MARC HAYEK. The tradition for fine watchmaking continues in its premises in Le Brassus and Villeret in the Vallée de Joux, placing the emphasis on craftsmanship and tradition. In 1988 Blancpain presented the “Six Masterpieces of the Watchmaking Art”, classic and understated wristwatches symbolizing the essence of watchmaking and highlighting movement complications rather than merely fancy case designs. Intended as a tribute to the countless watchmakers and craftsmen who as farmers turned to watchmaking for additional income during the cold and harsh winters, and in doing so laid the foundations of watchmaking and tool-making that remain the basis of the horological culture today. Watchmakers never rest on their laurels, and 1991 saw the presentation of one of the most complicated wristwatches ever made until today - the “1735”. It took 6 years of research, development and testing before the highly complicated and complex masterpiece could be presented, uniting the complications of the “Six Masterpieces” in a single watch! “Calibre 1735” comprises 740 finely finished movement parts. Only 2 specialists assemble these extraordinary micromechanical wonder. This particular example appears to be the only example fitted with special blue hands to increase readability and as the watch carries a lifetime warranty, it was serviced recently and is still under warranty until September 2019, a wonderful complication ready to be worn and appreciated.
