Overview
A traveller’s watch with a split-flap second time zone
The Jacob & Co. Epic SF24, reference ES100.30.NS.LH.A, in a titanium case, 45 mm across, 13.65 mm high at the centre and 16.70 mm high on the second time zone display. It has a black opaline and sunray-finished dial with rhodium-plated PVD hour markers, on a black alligator strap with a titanium deployant buckle.
The time zone indications are rhodium-plated, as are the skeletonised hands, whose tips are filled with SuperLumiNova.
SF stands for split flap, the display boards once common in train stations and airports. Jacob & Co. built this watch for frequent travellers and says many GMT watches look alike and offer little function. The second time zone is housed in a case extension, inside a wide sapphire tube, and shows a reference city and the time there.
One set of flaps is printed with 24 reference cities and the other with the digits that tell the time. A pusher on the side of the tubular extension advances both. The crown at 4 o’clock sets the local time, and moving it also moves the second time zone. Self-winding calibre JCAA02 has 473 components and a 48-hour power reserve. This version is limited to 101 pieces.
