Pierre DeRoche TNT Royal Retro GMT ½ Hour
Swiss luxury watch maker Pierre DeRoche announces a new addition to its popular TNT Royal Retro line. The new TNT Royal Retro model is equipped with a GMT display adjustable to the nearest half hour not via a corrector, but instead using the crown.
To avoid any loss of precision during adjustments, the GMT hours and minutes hands advance in 30-minute increments to guarantee exact half hours, without the movement stopping. A third indicator appears on the white part of the subdial if it is daytime in the zone of the second time zone; or in the black section if it is night-time.
Meanwhile, the TNT Royal Retro signature retrograde seconds hands pursue their fascinating path. To spice up the overall effect, two of the six original hands vanish in the lower section of the dial to provide space for the GMT indicator. The TNT Royal Retro GMT ½ Hour is available in a 201-piece limited series.
