<p>This Nomos Tetra Duo was launched at Baselworld 2019. The Tetra is the only square watch face from Nomos. Quirky yet cool, this watch does not need any extra adornment. The 27.5mm square case is understated. The white dial features the hours and minutes. This watch is powered by the Nomos in house Alpha.2 movement with an approximate 43 hour power reserve. </p>
