Roth was born into a watchmaking family in Nice, France. His grandfather and great-grandfather were both watchmakers and, following in their footsteps, he attended a three-year watchmaking course. Upon completion, he worked with several Swiss watch companies, including Jaeger-LeCoultre, Chaumet and Audemars Piguet. In 1973, he was instrumental in the revival of the French watch brand, Breguet, and stayed with the brand for fourteen years. In 1988, Roth launched his own brand and by 1992 he was already employing twelve watchmakers. However, production numbers were small, driven by the brand’s commitment to traditional production methods - for example, hand-finishing dials and painstakingly decorating movements. In 1994, he took on external investment and the new investors increased production numbers. Despite not being a majority shareholder anymore, Roth himself still remained involved. The company was eventually sold outright to Bulgari, with Daniel Roth leaving shortly after. A high level of hand-finishing is a feature of his work, from the dials to the movements themselves. He often chose to highlight this by creating open-work and hand-engraved versions of his models. He introduced a completely different case shape - one of his signature elements - and these were produced in yellow, rose and white gold, as well as platinum and occasionally steel. The dial variations were numerous, integrating colours from salmon to electric blue, with various different combinations found throughout his body of work. Today, Roth produces one-off creations, working closely with his wife and son, completing around three pieces a year.
