Today Berlin, tomorrow London, the day after tomorrow New York - for business people, globetrotters and pilots it has long been part of everyday life to move back and forth between different time zones. With the display of two time zones, gmt watches meet the complex requirements of the age of global communication. Precision is ensured by the Laco 330 calibre, a mechanical movement with automatic winding. It is based on the well proven caliber Sellita 330-1 and ticks behind a solid steel case back, which is decorated with an airplane relief.
