What is the background? A tablecloth? It's a fine example of wonderful collection of tessellating shapes!
A beautiful collection of all the Zeitwerks in all the metals (except YG). Standard ZW in WG, Striking Time ZW in PT, and Minute Repeater ZW in RG (or is it HG?). A fine collection, and a fine tessellating pattern! Exquisite taste, not only in watches too!
