With its groundbreaking city-time display, the Epic SF24 enters a bold new dimension entirely undiscovered by traditional watches. Named after its Split-Flap, 24-city, vertical second time zone display, the Epic SF24 is a jet-set world-traveler's watch that is unique in its complexity and utility. Remarkably challenging to engineer and manufacture, yet easy and intuitive to use: the functionality and design of the Epic SF24 render it prepared to take on the world.

The Exclusive JCAA02 Caliber powers the Epic SF24 and all its time indications. The time on the main dial is set via the crown located at the 4 o'clock position of the case. Once the hours and minutes have been set, the World Time Display is to be adjusted via the pusher dedicated to this purpose. With this done, the main dial and the second time zone display work together through a fully mechanical connection: as the main dial advances to the following hour, so does the split-flap hour display, making for a highly engineered audible and visible feat - not just when it is adjusted, but also once every hour, throughout its operation.

Comprising 473 components, including 163 for the Split-Flap display, the JCAA02 caliber's 48-hour power reserve is replenished by a self-winding rotor mechanism. Finished with high-end Cotes de Geneve, circular perlage graining and polished screwheads, it tastefully combines the values of traditional horology with the achievements only possible in cutting-edge, ultra-modern watchmaking.

The case of Epic SF24 measures 45 millimeters in diameter and 13.65 millimeters thick at its center, and 16.70 millimeters between the top of its World Time Display and the lowest point of its case. Its 18K Rose Gold or Grade 5 Titanium case with the case sides, pusher and crown in honeycomb pattern rubber. An anti-reflective sapphire crystal covers the main dial, and a specially curved sapphire crystal safeguards the Split-Flap display, allowing for unhindered viewing of its operation and the spectacular mechanisms inside. The case-back also features a sapphire crystal pane, here with a Jacob & Co metallized decor, proudly stating the name of the Epic SF24's creator.

The Epic SF24 comes with a high-contrast, solid anthracite opalin dial with Roman numerals to indicate the main time zone. Above it extends the Split-Flap display for the World Time's city name and its respective hour indication, with the minutes synchronized between the two. The skeletonized central hands and the hour indices have white luminescent coating for increased legibility under all circumstances.
