The Vanguard Sfumato Slim by Franck Muller is a masterpiece of artistry and horology, inspired by the Renaissance painting technique of Sfumato, which creates depth through subtle color transitions. Its dial features delicate gradients that darken at the edges and lighten toward the center, inviting calm and reflection. Powered by an in-house automatic movement with a 40-hour power reserve, the transparent sapphire caseback reveals exquisite finishes, including Geneva stripes, perlage, and a moonphase indicator. Each dial is hand-painted with layered colors and coated with lacquer for depth and protection. Available in a refined palette, it embodies elegance, precision, and timeless artistry.
