Considered to be one of the most remarkable contemporary watchmakers, Daniel Roth trained in his early career with high-end brands like Audemars Piguet and played a crucial role in the revival of Breguet. Offering his creative take on traditional Breguet-inspired watches, of which this piece is an enduring testament, he designed his double-faced Tourbillon, reference C187, in 1988 and released it the following year as a way to announce his independence and the creation of his eponymous brand.

Upon launch of his brand, Roth immediately established his personal design language, the most obvious being the unusual ellipsocurvex shape, hands with pointed tips and dials with guilloché patterns, all elements you can find in the present white gold Regulateur Tourbillion. The Daniel Roth reference C187 is probably one of the watchmaker's better-known creations. On the front side, taking center stage, is the large tourbillon escapement with an original triple arm seconds hand featuring three hands of different lengths that indicate the seconds on three different seconds registers, each calibrated for 20 seconds. The caseback features a retrograde power reserve and date indications.
