The sculptural tonneau-shaped case is crafted in warm 18-carat rose gold, displaying the refined architecture and elegant curvature characteristic of Parmigiani Fleurier’s early creations. The stepped bezel, finely fluted along its edges, adds depth and a strong neoclassical presence, while the polished surfaces and gently cambered profile emphasize the watch’s sophisticated proportions. The sapphire caseback reveals the movement in full, framed by a rose gold surround secured with visible screws, underscoring the technical and artisanal intent of the piece.
