This watch is accompanied by Thomas Engel Certificate No. 2 signed and dated 1980, Swiss Rating Certificate, original fitted presentation box containing a spare main-spring and a set of gold Breguet hour and minute hands and an alternative 18k gold engine-turned case back with three gold fishes on a central blue enamel disc
Professor Thomas Engel holds around 120 patents in organic chemistry and numerous honours and prizes in the field of researching polymers, including the 1972 "Diesel Prize" that was jointly won with Dr. Wernher von Braun, one of the most important rocket developers and specialist of space exploration. Not only a famous watch collector but also a passionate "self-made" maker of technically outstanding timepieces, he often incorporates many style elements from Breguet.
These watches, as exhibited in the present lot, are now known as the "Engel Breguets" and are considered to be highly important collectors' pieces.
