But Maurice Grimm did more than that - he developed 3 tourbillon watches (almost) single-handedly: - The ultra-thin automatic tourbillion for Audemars Piguet (caliber 2870) in 1986 - The Audemars automatic tourbillon with the crown on the back of the case, date and power display (caliber 2875) in 1991 - The first central tourbillion, for Omega (caliber 1170) in 1994 I have seen the prototypes of these tourbillon watches when I met Mr. Grimm... and they were breathtaking!
How did he get to design tourbillons? As
Mr. Grimm had quite some freedom within Omega due to the respect he had
earned as a watchmaker over the years, he was allowed to develop the
first design (caliber 2870) more or less as he wished, and Audemars
Piguet bought the ready watch concept since Omega, by 1985 a part of the
Swatch Group, did not find a fitting place for it in its product range.
Audemars kept the watch almost as it was, even the dial design. The
only thing they changed was the place of the little opening which shows
the hammer winder of the automatic movement.
