How to read a GENUS watch—and who created the business behind it

GENUS is a confirmed Geneva-based watch brand co-founded in 2019 by Catherine Henry and Sébastien Billières. GENUS identifies Billières as watchmaker/co-founder and Henry as co-founder and COO responsible for business development.

The GENUS display uses revolving hour indices, a travelling tens-of-minutes indicator and a separate units-of-minutes disc. GENUS describes manufacture in its workshop and selected specialist suppliers; these claims do not establish that every component is made internally.

GENUS GNS1.2 received the 2019 GPHG Mechanical Exception Watch Prize. 12

The work and why it matters

Billières’ earlier contract-manufacturing activity began in 2007; GENUS’s own founding is dated 2019. The brand story says two patents were filed for the display architecture.

The official GENUS site presents GNS1.2 and GNS2 collections, including a GNS1.2 Dragon. The founder biographies identify business and technical leadership, but do not establish exact equity ownership or a legal-company continuity chain. 13
