Limited to 50 pieces worldwide, the Terra Nova Jumping Hour Aventurine pairs a deep blue Aventurine dial with a frosted 904L stainless steel case, creating a striking play of light and texture. The cushion-shaped 40.5mm profile maintains contemporary field watch proportions, while diamond-polished Aventurine reveals constellations of sparkle beneath its midnight hue.
Offset apertures present the Jumping Hour's signature left-to-right flow, complemented by Super-LumiNova® accents and a luminous central seconds hand for clarity in any light. Powered by the exclusive BC634 calibre, the hour jumps instantaneously in under one tenth of a second, offering precision and mechanical drama with a 56-hour power reserve.
Finished on a quick-release blue gradient leather strap, this limited edition blends mechanical ingenuity with subtle luxury-an elegant statement within the Terra Nova collection.
