The Hamilton Thin-O-Matic series was born in the 1960s, with its first model making a big splash in the watch world. Today, the new edition carries on the legacy with a modern twist on classic designs. Think smooth, curved dials and second hands, along with snap back closures and a special engraved Hamilton logo on the case back. This logo features the brand's iconic crest, adding an extra touch of heritage to this already prestigious line.
