This Arnold & Son Nebula is a 50 pc limited edition at 38mm size. The skeletonised movement is unique to this reference and is designed to represent a Nebula (an exploding star) so it radiates out from the center. Twin barrels provide almost 100h of power reserve. Hand finished bevelling and polishing. Even the spokes for all the wheels are bevelled and hand polished. The Arnold calf leather strap is actually a dark grey with hand applied patina and the Arnold signed buckle.
