The GoS01 is a hand-wound mechanical movement manufactured by ETA SA and released in 2013. It serves as GoS's first in-house caliber, notable for its bridge and balance cock crafted from damascus steel—a material choice requiring extensive hand-finishing. The movement features Glucydur shock protection. It powered the Winter Nights – For Purists, originally planned for 10 pieces but discontinued after only 5 were produced.
