Founded in 2004, Romain Jerome built watches embedded with fragments of history, such as steel salvaged from the Titanic. Other pieces used lunar material from NASA's Apollo 11 mission and volcanic rock from Iceland's Eyjafjallajökull eruption. Under CEO Manuel Emch, from 2009 to 2017, the brand moved into pop culture collaborations with bold, steampunk-inspired designs like the Space Invaders and Batman-DNA collections. With oxidized finishes, arrow-tipped hands, and oversized cases, these limited-edition watches appeal to collectors who want wearable art with provenance.
