Jacob & Co. Five Time Zone Steel Diamond JCM-30

The Jacob & Co. Five Time Zone Steel Diamond JCM-30 commands attention with its bold 44mm stainless steel architecture, elevated by a mesmerizing bezel set with meticulously selected brilliant-cut diamonds. Each stone is hand-placed to maximize fire and scintillation, creating a luminous frame for the complex multi-time zone dial. The integrated bracelet, crafted from solid steel links with a refined brushed and polished finish, flows organically from the case, ensuring a luxurious tactile experience. The sapphire crystal, treated with anti-reflective coating, offers unimpeded views of the layered dial, where applied indices and luminous hands provide optimal legibility across all five zones. This seamless fusion of high jewelry and robust engineering defines the Jacob & Co. aesthetic.

At the heart of this horological instrument beats an automatic movement enhanced by a proprietary five-time-zone module, a complication developed exclusively for the discerning traveler. The mechanism allows simultaneous tracking of five distinct time zones via independent sub-dials, each adjustable via the crown and dedicated pushers — a feat of mechanical ingenuity that transforms global timekeeping into an intuitive art. The rotor, visible through the exhibition case back, bears the Jacob & Co. insignia and is finished with Côtes de Genève and perlage, reflecting the brand’s commitment to haute horlogerie standards. With a power reserve of approximately 42 hours, the movement ensures reliable performance across continents, making it as functional as it is spectacular.
