"Modern Mechanical" in its purest form, aimed at people who have the courage to leave the beaten ways to explore their own paths. The Aurora combines a color changing & CVD-coated hand guilloché dial with the brand's classic style elements, such as the fluted bezel, onion crown and straight lugs.
Open Gear ReSec Aurora
The ReSec Aurora features a 3-dimensional regulator construction with a retrograde second and exposed mechanics. The massive Super-LumiNova ceramic blocks shine bright and bring light to the darkness of icy polar nights.
