At first glance, the NOMOS watches Tangomat and Tangomat Date appear to be little more than an enlarged Tangente. In them, however, the first NOMOS automatic calibres are at work: these movements – Epsilon and Zeta – were designed, developed and manufactured entirely at NOMOS. It is thanks to them that NOMOS was knighted with the additional distinction "manufactory." In 2005 consumers and journalists tested the Tangomat and Tangomat Date models over a period of several months and both watches will now go into normal serial production.
Tangomat and Tangomat Date are watches, whose excellent accuracy are already highly commended. Their backs are fastened with six screws and the watches are waterproof to 30 metres.
