Nomos Glashütte Tangomat Ruthenium Datum Ref. 604

Tangomat is similar to Tangente, just a tick larger: Powered by a self-winding caliber and, like its little sister, it has long been a classic. In this version, the dial has been coated with ruthenium—a metal in the platinum group—turning it into a deep black. The watch features a patented NOMOS date indicator, while the in-house built Zeta movement inside ensures the highest rate accuracy.
