Singer Karol G spotted wearing a Jacob & Co

Karol G was recently photographed wearing one of Jacob & Co.'s most diamond-saturated high-jewellery timepieces — the Boutique Watch Factory in full diamond configuration. The sighting aligns perfectly with the artist's well-documented affinity for maximalist fine jewellery, and this particular reference represents the upper echelon of what the New York-based maison produces outside its mainline complications.

The Jacob & Co. Boutique Watch Factory diamond edition is built around a square 18K white gold case set entirely in diamonds across three distinct cutting styles. The bracelet deploys 48 Ashoka-cut diamonds totalling 23.63 carats — the Ashoka being a proprietary modified rectangular brilliant cut originally developed by William Goldberg, delivering unusually high light dispersion from its 62 facets. Flanking these are 80 round brilliant-cut diamonds at 15.43 carats, while the dial itself is framed and populated by 16 Asscher-cut stones totalling 3.28 carats, lending the face a structured, geometric quality that references Art Deco sensibility. Total stone weight across the piece exceeds 42 carats. The movement inside is a Swiss quartz calibre — appropriate given that the watch is conceived first as a jewellery object, with timekeeping secondary to the display of stones.

From a collector standpoint, the Boutique Watch Factory occupies a niche that few manufactures attempt seriously: the fully gem-set jewellery watch at investment grade. Jacob & Co. has long operated at the intersection of entertainment culture and haute horlogerie, and pieces like this one are produced in extremely limited numbers, often as bespoke or near-bespoke commissions through the brand's Boutique Watch Factory atelier programme, which offers clients direct input on stone selection and configuration.

Karol G has become one of the most commercially successful Latin artists of her generation, with record-breaking tours and multiple Latin Grammy wins cementing her cultural reach. Her jewellery choices — consistently high-carat and bold — function as deliberate aesthetic statements that reinforce her public persona. Pairing this Jacob & Co. piece with a minimal black ensemble demonstrates restraint in styling while letting the watch's 42-plus carats do the visual work.

At a list price of $750,000 (approximately £610,000), this Jacob & Co. Boutique Watch Factory diamond configuration sits firmly in collector and ultra-high-net-worth territory. Secondary market activity on pieces of this specification is limited given production volumes, but comparable fully-set Jacob & Co. jewellery watches have held value well, with grey market premiums possible on particularly well-documented stones.
