Story

With its groundbreaking city-time display, the Epic SF24 Tourbillon 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 Tourbillon 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.

Split-flap World Time Display

The patented World Time Display of the Epic SF24 Tourbillon comprises a total of 163 components, allowing it to work at a press of a button, on demand, with exceptional feel and reliability. Inspired by traditional split-flap timetable displays seen on airports and in evergreen cinema classics, every press of the button integrated into the left hand side of the Split-Flap extension turns it to the next city name - and, along with it, also advances the Arabic hour display by one.

Designed to boldly stand out among traditional 2nd time zone indications so omnipresent in modern watchmaking, the Split-Flap display is a spectacular engineering achievement unto its own not simply for its complexity, but for its singular ability to bring a smile of appreciation to even the most tired of world travelers.

Epic Sf24 Tourbillon Caliber

The Exclusive JCAA03 Caliber powers the Epic SF24 Tourbillon 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 528 components, including 163 for the Split-Flap display, the JCAA03 caliber's 48-hour power reserve is replenished by a self-winding rotor mechanism. Finished with high-end Cotes de Geneve, circular graining and anglage decoration techniques, it tastefully combines the values of traditional horology with the achievements only possible in cutting-edge, ultra-modern watchmaking.

Flying Tourbillon

Whereas the tourbillon was originally invented to be a single-axis, rotating cage secured from above as well as below to carry the regulating organ of a mechanical pocket watch for improved timekeeping performance, the Epic SF24 Tourbillon presents this two-century old invention in a yet more spectacular way.

The one-minute flying tourbillon of the Epic SF24 Tourbillon features a delicately decorated cage that encapsulates the balance wheel, hairspring, escape wheel and a number of other crucially important components. This openworked cage not only features an elaborate web-pattern in its architecture, but is only secured from underneath, allowing for an unobstructed and full view at the ultimate refinement of its detailing and operation. It is a constellation of superbly finished components that, when assembled and fine-tuned expertly, allows the JCAA03 to keep accurate time throughout its 48-hour power reserve.

Caseback

The Epic SF24 Tourbillon Baguette Green shows a little more of its true nature when looked from the backside. Under the transparent sapphire caseback, a printed golden globe reminds of the timepiece's main function. It's a multiple timezone watch, able to tell the time it is where you stand and somewhere else, wherever you wish among the 24 main time zones on Earth.The complex details of the case also come to light, such as the honeycomb pattern inside the hollowed lugs and caseband, the graphic caseback structure made of 18K Rose gold, and the green pusher designed to set the second time zone.

Case & Crystal

The case of Epic SF24 Tourbillon 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 case is crafted from 18K rose gold, set with 79 baguette-cut white diamonds. The case sides, pusher and crown are inset with 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, with a Jacob & Co metallized decor, proudly stating the name of the Epic SF24 Tourbillon's creator.

DIAL & HANDS

The Epic SF24 Tourbillon comes with city name or honeycomb pattern dial in green opalin, with baton hour markers for the main dial. Above it extends the Split-Flap display for the World Time's city name and its respective hour indication, in matching green. The skeletonized central hands and the hour indices have green luminescent coating for increased legibility under all circumstances.
