In collaboration with Huckberry, UNIMATIC presents Earthform Collection, a limited-edition trio of Italian-made tool watches inspired by Earth’s natural Beauty.
This is the first-ever UNIMATIC collaboration with the men’s brand and digital magazine Huckberry.
The new UNIMATIC x Huckberry Earthform Collection includes three Quattro U4S models: Lichen, Redwood and Sandstone.
For this collection, the Italian watch brand drew inspiration from the orange striations of the Grand Canyon, passing through the soft teal lichen that grows all over Yosemite, and ending with the sun-drenched leaves of the towering redwoods that line the West Coast.
Each watch features an automatic Swiss movement Sellita SW200-1 fitted in a 12.4mm sandblasted stainless steel case. The co-branded screw-in steel case-back features limited edition number and the texture dedicated to the particular model.

The Lichen Modello Quattro ref. U4S-HG features a lichen grené dial with Super-LumiNova®C5 and cool gray open second rail and dial trims.

The steel case-back highlights a granite texture engraving. This model comes fitted on a pale blue TPU two-piece strap and extra gray nylon NATO strap.
The Redwood Modello Quattro ref. U4S-HM features a redwood grené dial with Super-LumiNova® light green and cool gray open second rail and dial trims.
It comes fitted on a meadow green TPU two-piece strap and extra gray nylon NATO strap. This model’s case-back spotlights a moss texture engraving.

The Sandstone Modello Quattro ref. U4S-HS feature a sandstone orange gradient grené dial with Super-LumiNova®C1 and brown open second rail and dial trims.
It comes fitted on a sandstone orange TPU two-piece strap and extra gray nylon NATO strap. The stainless steel case-back of this model has a Sandstone texture.

Each reference is available in a limited edition of 75 pieces priced at 850 EUR before taxes.
