Brandt Jeanrenaud et Robert (also known as Robert Brandt et Jeanrenaud) was an early 19th century Swiss watchmaking firm based in La Chaux-de-Fonds. The company operated from the 1800s to the 1820s/1840s and was best known for pieces made between 1810 and 1820.
–
Brandt Jeanrenaud et Robert made high quality pocket watches and clocks with remarkably complex mechanisms, always distinguished by interesting or unusual features, such as visible dials or independent jumping seconds.
 –
The company was presumably renamed Robert Brandt & Cie, continuing family and business traditions into the later 19th century.

Some of the company’s historical timepieces are preserved in institutions like the Musée d’Art et d’Histoire de Neuchâtel.
