<p>The Tetra is the only square watch face from Nomos. Quirky yet cool, this watch does not need any extra adornment. The 29.5mm square case is understated. The tempered blue steel hands pop against the plain white dial. This watch is powered by the Nomos in house Alpha movement with an approximate 43 hour power reserve. </p>
