The Richard Mille RM 019 'Celtic Knot' Ladies' Tourbillon is a masterpiece that seamlessly blends artistry with horological precision. Its intricate design features a diamond-studded Celtic Knot motif that elegantly weaves through the movement, connecting the winding barrel, power reserve indicator, and tourbillon in an endless cycle. This symbol, dating back to the 5th century, represents the timeless nature of the spirit and the uninterrupted flow of life. The watch is housed in a tonneau-shaped case crafted from 18K white gold, measuring 45 x 38.3 mm, and is complemented by a black leather strap. The baseplate is made of black onyx, a stone believed to deflect harmful energy and provide stability. The manual-winding tourbillon movement offers a power reserve of approximately 48 hours. This exceptional timepiece was introduced in 2009 and has been recognized for its innovative design and craftsmanship.
