Those who love the purist face of the Tangomat model by NOMOS Glashütte but don’t want to relinquish a second time zone may choose the Tangomat GMT Plus and do as follows: before landing in a foreign country, ask for the time difference, then press a button to set the new time zone. The difference (i.e. +2 or -3 hours) is shown in a window at the nine o’clock position. A time disc in the three o’clock position reminds you of the time at home. Movement: ξ (Xi) – manufactory caliber with automatic winding and world-time indicator; case: stainless steel, five parts; dial: galvanized, white silver-plated; hands: steel, tempered blue.
