Catalogue description
Dealer description — Analog/Shift
If you’re a constant traveler, a dual-time watch is one of the handiest pieces of kit you can keep on your person. But if two time zones are handy, then five would be positively life-altering, no? Well, there’s one way to find out: Strap on the Jacob & Co. H24, which does, in fact, display the time in five separate locations simultaneously — with a mechanical movement! When Jacob Arabo came to the U.S.A. from the U.S.S.R, his father gifted him a timepiece that displayed two time zones against a gold-plated map of the world. Thus, the idea of the Five Time Zone was born, which Arabo ultimately learned to execute following hard work apprenticing in jewelry design and watchmaking. Originally a quartz watch — the Swiss initially refused to work with him — Arabo eventually found suppliers and began making a mechanical version. This particular H24 Five Time Zone is indeed a Swiss-made marvel: Housed in an imposing 47mm stainless steel case with a sapphire crystal, a polished bezel, and five (!) signed crowns, it features a handsome, sunburst blue dial with applied ‘Roman’ indices, a date window at 3 o’clock, and four subdials displaying the time in Los Angeles, New York, Paris, and Tokyo, each of which is calibrated in 24-hour time. A bright red “feuille” handset rounds out the dial, ensuring good legibility despite the multitude of time-telling displays. Powering this incredible ensemble of time-tellers is an automatic ETA A07.111 movement adjusted to display five time zones. Paired to a blue alligator leather strap with a signed, stainless steel deployant clasp and dating to the 2010s, it’s the type of watch that’s going to spark questions from passersby, so be prepared!
Historical context
Contemporary Horology (2010 – Present)
Silicon components, connected watches, optical-lattice research clocks and a thriving independent scene.
Smartwatches became the world's best-selling watches, while mechanical watchmaking focuses on craft, innovation (silicon components, new escapements) and independent makers.

Wristwatches
Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.
After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.
What to look for
- The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
- The calibre: its maker and number are often stamped under the dial or on the bridge.
- Originality of dial, hands and crown — refinished ('redial') dials are common.
- Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.
Dating clues
- Wire-lug cases: before c. 1925.
- Water-resistant screw-down cases: from 1926.
- Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
