The dial of the Daniel Roth Tourbillon Rose Gold is crafted in collaboration with Kari Voutilainen’s workshop, where each vertical line is hand-engraved using a straight-line engine. A highly respected figure in haute horlogerie, Voutilainen’s career began in Switzerland, where he trained as a watchmaker and refined his craft at some of the most prestigious workshops in the industry, like Parmigiani Fleurier. In the early 2000s, he established his own workshop, gaining recognition for his mastery of complex complications like tourbillons and unique time displays, as well as his exceptional finishing techniques, which often feature hand-engraving and guilloché work.
