Every so often, a watch surfaces that feels more like alchemy than horology, and this Omega “Trigold” Ultra Slim is precisely that.
Crafted in a shimmering blend of yellow, white, and pink gold, dressed in a Florentine finish and crowned with diamonds, it’s a masterpiece that blurs the line between jewelry and watchmaking.
Possibly unique and likely born from a special commission, it embodies Omega’s most imaginative era, a collector-grade dream where design, craftsmanship, and rarity unite in perfect harmony.
Please read the condition report carefully and refer to the high-resolution pictures to help you assess the overall condition of the watch.
