Alterum Worldtimer Horizon

$3,650.00 USD
The Alterum story starts with a lesson in simplicity — designing less, cutting away the chaos. The result is a fresh, original-looking watch — the Alterum Worldtimer — which won the inaugural Dubai Watch Week × Grail Watch competition in 2024. Its calling card lies in a pared-back dial that does away with conventional hands.
Following the sold-out edition of the Alterum Worldtimer and our New York and LA editions, our fourth and final iteration the Alterum Worldtimer Horizon completes the quartet with a pure white dial. “Singapore” is highlighted in red on the city disk, an intentional detail created to honor the partnership and collaboration between Revolution and Alterum.
As in earlier editions, there are no hands on the dial. Instead, time is told via four concentric disks: the innermost dial tracks minutes; the next tracks hours and the following displays the 24-hour time with a day/night indicator. The outermost disk features 24 cities that allow wearers to easily track each time zone.
Keep going past the dial, and you'll notice a stepped bezel that completes the circular motif that runs throughout the Worldtimer. Two crowns sit at 2 and 4 o’clock, slightly recessed into the case and bearing a white line and the Alterum logo respectively. The former lets you set the bidirectional city disk while the latter winds the watch and sets the time. Both case and bracelet are vapor-blasted for a softer, more contemporary finish

BOLD MINIMALISM

The dial consists of four concentric circles: the innermost dial tracks minutes; the next tracks hours and the following displays the 24-hour time with a day/night indicator. The outermost disk features 24 cities that allow wearers to easily track each timezone. Instead of traditional hands that mark the passing of time, printed graphic elements are instead employed to maintain visual cleanliness.

Architectural Influence

The architecturally-minded will draw a line from the concentric motifs on the watch to the tiered structure of New York's Guggenheim Museum, the sculptural masterpiece by American architect Frank Lloyd Wright. An icon of American design, Wright's blueprints for the museum served as a key reference for the Alterum Worldtimer, from the multi-ringed dial to the grooved bracelet links that mirror the interior and exterior experiences of the Guggenheim.

American Design, Swiss Made

To help bring his vision to life, founder Justin Walters partnered with the Swiss specialist manufacturer, Roventa-Henex. Even if the name is unfamiliar, chances are you’ve tried on or even owned one of the watches they manufacture. They are Switzerland’s most renowned 'white label' watch factory and manufacture timepieces for some of the biggest brands in the industry. The resulting tactility of the Worldtimer — from the engaging jumps on the city disk to its supple articulating links — stands up to the most discerning collector.

Customized Calibre

Powering the Worldtimer is the SW330-2, a well-loved GMT varient of Sellita's workhorse that has been further customized by Roventa-Henex. Gone is the superflous date wheel and central seconds; the GMT module is modified to display a 24 city disk on the outermost ring, instead of a central GMT hand.
