Writer Giorgia Mondani spotted wearing a Jacob & Co

Milan-based watch author and collector Giorgia Mondani — whose books on Rolex and Patek Philippe have become essential references in the collector community — was recently photographed wearing a Jacob & Co Epic X Chrono in Black DLC titanium with full lime-green trim. The color-coordinated shot, posted to social media, showed Mondani pairing the watch deliberately with a matching green silk shirt, underlining her status as someone who wears watches as a genuine expression of personality rather than mere status signaling.

The Jacob & Co Epic X Chrono is built around the brand's in-house JCAM37 automatic movement, a column-wheel chronograph calibre beating at 28,800 vph with a 48-hour power reserve. The 44mm case is crafted from grade-5 titanium and finished with a Black DLC (Diamond-Like Carbon) coating that drops the weight dramatically while delivering exceptional scratch resistance. The bi-compax dial architecture places subsidiary seconds at 9 o'clock and a 30-minute chronograph counter at 3, flanked by a skeletonized central bridge that exposes the movement architecture beneath. The vivid green accent package — inner tachymeter bezel, crown, pushers and injected rubber strap — is one of several colorway options Jacob & Co offers across the Epic X family.

The Epic X Chrono launched as Jacob & Co's most credible entry into the sport-chronograph segment, earning respect from collectors who had previously viewed the brand primarily through the lens of its diamond-set fashion pieces. The use of a proprietary movement, rather than an ebauche, shifted the conversation. The case architecture, with its angular lug system and helmet-style bezel, draws clear inspiration from motorsport and extreme-sport aesthetics without resorting to parody.

Giorgia Mondani brings significant horological credibility to any watch she chooses to wear publicly. As the author behind the most comprehensive published guides to vintage Rolex references, her endorsement of a contemporary independent brand carries weight among serious collectors who might otherwise overlook Jacob & Co.

At a retail price of $28,000, the Epic X Chrono in Black DLC green sits in competitive territory against established sport chronographs from Hublot and Richard Mille's entry tier. Grey market values have remained relatively stable, reflecting steady rather than speculative demand — a sign of a watch bought to be worn.
