Beautiful, unique, likely commissioned from Maison Belga d'Longueville. The domed hour hand is characteristic of d'Longueville, as seen in other models. d'Longueville is a contemporary Belgian brand founded by Didier Longueville, known for creating watches that blend Swiss engineering with a distinctive artistic aesthetic. This specific model emphasizes the skeletonized movement, a visual complication that requires the meticulous removal of excess material from the bridges to reveal the watch’s beating heart. The choice of dials with elaborate textures and vibrant colors is a hallmark of the brand, making each piece a unique style statement. Never worn except to see the effect in person on the wrist; it was impossible not to admire it.
