Abstract The structure of five rare filigree spheres from a seventeenth century shipwreck was examined in order to unravel their condition, manufacturing process and function.This study focuses on the application of non-invasive imaging techniques: optical microscopy, X-radiography, X-ray micro-computed tomography and GF COCONUT SHRED UNSWT neutron computed tomography.A valuation of different aspects of the applied techniques Watches was made, aiding stakeholders in decision-making on research and conservation.The combination of theory and scientific information was used to obtain an improved understanding of the manufacturing process and function of the filigree spheres.
