The Dart Frog Blue dial changes character as light moves across its surface, shifting from soft powder blue to vivid blue depending on the angle and source. Unique applied and polished indices with cobalt colored infill, applied and polished numerals, and complementary hands with polished edges create depth and reflection, while the balanced layout keeps the dial clear, refined, and easy to read.

Design Inspiration & Charity
With every Trey Stone watch sold, 10% of net proceeds will be donated to charity. For the Dart Frog Blue model, the default charity is World Wildlife Fund (WWF), supporting the protection of wildlife, natural habitats, and ecosystems around the world. At checkout, you may keep WWF as your selected charity or choose from another of our list of charities.
The Dart Frog Blue model draws inspiration from the blue poison dart frog, Dendrobates tinctorius azureus, native to isolated rainforest habitats in southern Suriname. Kaieteur Falls in neighboring Guyana, one of the Guiana Shield’s most renowned geological landmarks, evokes the humid, mist-filled rainforest environment of the wider region. The frog’s vivid blue coloring and irregular dark markings are reflected in the dial’s light blue surface, deep blue accents, and black details, resulting in a design with vibrancy, contrast, and distinction, for a strong connection to its natural inspiration.
