Studio Underd0g series one, the watermel0n, go0fy panda, desert sky and mint ch0c Chip chronograph watches. The 01Series chronograph models feature a stunning mid-century silhouette while integrating a refreshingly modern dégradé dial. Each model has its own very unique inspiration for the colour and design scheme, whilst housing the ST-1901 mechanical hand-wound movement. This movement has a very rich history; starting life as a Swiss Venus Cal.175 before the tooling and technical drawings were sold to the Chinese Airforce in the 1960s. The latest version in the Gen2 01Series also features a silver coloured Swan Neck regulator.
