Marathon Jumbo Self-Setting Wall Clock
Marathon Jumbo Self-Setting Wall Clock

Marathon Watch Company traces its roots to 1904, when Hersh Wein founded Weinstrum Watch. His son Morris Wein founded Marathon in Montreal in 1939, and by 1941 the brand was supplying wristwatches and timing instruments to Allied forces.
Today Marathon is headquartered in Vaughan, Canada, and assembles its watches in its own factory in La Chaux-de-Fonds, Switzerland. It still develops and supplies timepieces under contract to the Canadian, U.S. and British governments and other Allied forces.
The range is built around three families: the Search and Rescue (SAR) dive watches, the Navigator pilot watches and the General Purpose field watches, lit with tritium gas tubes and MaraGlo luminescence.

When the U.S. government needed a wall-mounted atomic clock for its offices—something large, legible, and always accurate—Marathon answered the call. Featuring a display that’s easily read from up to 30 feet away, the Jumbo Wall clock also provides a gold standard level of accuracy.
The clock's self-setting and self-adjusting functions use radio frequencies broadcast from NIST's Colorado Atomic Clock and the DCF77 transmitter near Frankfurt, Germany.
Over the years, thoughtful improvements have been made to the original design:
- A slimmer profile for easier wall mounting
- Option to display in six languages: English, French, Dutch, Italian, German, or Spanish
- More intuitive controls for simplified setup and adaptability for multiple time zones across the globe
- Temperature select in Celsius or Fahrenheit
- Date / Month or Month / Date display
- Dual antenna to support both North American and European radio signals—critical for U.S. operations overseas
- A split-display design that separates the time and other functions, reducing power usage without sacrificing visibility
With its oversized digital readout and automatic synchronization with radio signals, the Jumbo Self-Setting Wall Clock remains a trusted timekeeping tool—in offices, classrooms, operations centres, hospitals, and homes across the globe.
(W x D x H): 16.7 x 1.9 x 10.6 in (42 x 4.9 x 27 cm)
