They are the Ochra, Terra, Salvia, and Basalt references, and together they form the Tetra Origins collection that feels just as playful as watches we’ve seen come before it, yet with a bit more subtlety in a more desaturated spin. To me, the Tetra often feels like the odd duck in the lineup. Obviously, the square-shaped case and Art Deco-inspired lugs are the brand’s most unique (or, alternatively, polarizing) design details. But at the same time, it’s a line that gets rarely updated and offers very few options to begin with. So when I saw these four versions a few months ago, back in Glashütte, it felt like a nice breath of fresh air.
