Global time reinterpreted through mechanical precision
A departure from traditional world time displays, this category introduces a mechanical system inspired by split–flap airport boards, where city names transition through a vertical aperture with instantaneous clarity. Developed by Jacob & Co, the Epic SF24 integrates this system into a wristwatch format, allowing the wearer to track global time zones through a dynamic, mechanically driven display rather than static indicators.
The mechanism operates through a series of rotating drums that control the progression of city names, synchronized with the primary timekeeping movement. This requires precise coordination to ensure accurate transitions and alignment with the selected time zone. In more advanced executions, such as the Epic SF24 Tourbillon, this display is combined with a regulating tourbillon, adding another layer of mechanical complexity. The result is a category that merges functional global timekeeping with a distinctive mechanical presentation, offering both clarity and innovation in how time across regions is displayed.

Precision across time zones
The split-flap display system relies on controlled mechanical sequencing, where each transition must align perfectly with the underlying movement to maintain accuracy across multiple time zones. This introduces a level of technical coordination not typically found in conventional world time watches.
Integration of this mechanism within a compact case requires careful engineering, ensuring that the display remains legible while preserving the stability of the movement. The result is a refined approach to global timekeeping, where clarity, mechanics, and functionality operate in complete alignment.
