High Jewelry Meets High Watchmaking Jacob & Co. built its reputation on the seamless integration of extravagant gem-setting and ambitious watchmaking. The Brilliant collection, introduced in 2017, serves as the ultimate canvas for this philosophy. This reference is a premier example, taking a classic rose gold case and transforming it into a spectacle of light and color. The "Rainbow" execution is a signature for the brand, requiring an expert eye to source and set a perfect gradient of natural sapphires. It is a watch that completely blurs the line between a timepiece and a piece of world-class jewelry. A Masterpiece Of Gem Selection The success of a rainbow setting is entirely dependent on the quality and arrangement of the stones. Each sapphire on the bezel is selected not just for its own merit, but for how it flows into the next, creating an unbroken spectrum. The dial is a second showcase of skill, with a glossy white finish serving as the backdrop for a pave diamond center and sapphire hour markers that echo the bezel. This is not simply a watch with gems added. It is a complex composition where every element is chosen to amplify the others, a skill Jacob & Co. has perfected since its founding. Excellent, Complete, And Barely Worn This 2017 example is in excellent overall condition, showing minimal signs of wear. The 18k rose gold case is sharp, appears unpolished, and the numerous sapphires and diamonds on the bezel, dial, and buckle are flawless. The glossy white dial is clean and vibrant. The original leather strap and rose gold buckle are present and in fine shape. This piece is offered as a full set, complete with its original box and papers. As with every watch we offer, this piece has been verified as mechanically sound and is ready to wear. The Definition Of A Statement Piece This is not a watch for someone who wants to fly under the radar. It is an unapologetic display of craft and confidence, made for an owner who appreciates the technical skill required to create such an object. While it is a sizable watch, the Brilliant case was designed to be versatile, and its seamless construction allows it to wear comfortably. It is the ultimate expression of modern horological luxury, perfect for a collector who understands that sometimes, more is more.
