The GMT complication watch is intrinsically linked to the brand’s history and pioneering spirit. In 1911, Longines filed a patent for the first pocket watch displaying two time zones. And as early as 1908, a model designed for the Ottoman Empire (Turkey) could convert Turkish time into Western time. In 1925, the brand produced for the first time a series of wristwatches displaying a second time zone. This history is still being written today, with several flagship models such as the Longines Spirit Zulu Time, the Longines Master Collection GMT and the HydroConquest GMT.
