De Grisogono was founded in Geneva in 1993 by Fawaz Gruosi, a designer who had previously worked at Harry Winston and Bulgari before starting his own house. Gruosi built the brand's reputation on a then-unconventional material — black diamonds, largely overlooked by the jewellery world until he made them the house's signature — earning him the nickname "King of Black Diamonds." De Grisogono entered watchmaking in 2000 with the Instrumento No Uno, and over the following two decades became known for bold, asymmetric case designs and jewellery watches that treated horology as an extension of high jewellery rather than a separate discipline.
The original De Grisogono company filed for bankruptcy in 2020; the brand was acquired by Dubai's DAMAC Group in 2022. Watches from the Gruosi era (1993–2019) — the period the brand's design language and reputation were built on — are today only accessible through the pre-owned market.
