In researching this article, I immediately thought of of NOMOS Tetra line, and began looking into some of the sizes they might offer. The NOMOS Tetra, I recalled, accounted for some eminently wearable square watches. While scanning the NOMOS site, I alighted on the recently released Tetra Neomatik 39 and eagerly dove into the specs. To be honest, I was shocked at the thought this company would make a 39 mm square watch. It just seemed so big for them. However, this watch does not actually measure 39mm at all. Its sides, it turns out, are 33mm each, yielding a diagonal measure of 46mm. It appears the name, Tetra Neomatik 39, isn’t based so much on any actual measurement of length, but rather how this watch wears. I asked Merlin Schwertner, the Vice President of NOMOS USA, if this is true, and he confirmed that it is.
