Catalogue Note

Professor Thomas Engel (1927-2015) was a distinguished scientific and inventive chemist in the international field of plastics and polymers.  He received many notable awards for his work, including the Diesel Prize in 1972, which he shared with the rocket and space technologist, Dr. Wernher von Braun.  Outside his field, Engel developed a keen interest in watches with a particular focus on the work of Abraham-Louis Breguet.  This interest led him to begin production of his own pocket watches, all of which were influenced by the watches of Breguet.  Engel developed a relationship with Zenith and relied on them to create the movements for his pieces.  Engel designed a prototype with a Breguet style dial for Zenith, using their cal. 68., which led to the production of seventy-five cal. 68 gold cased watches, including lots 156 and 157 in this sale.
