The Intra-Matic from Hamilton’s Basil 2012 collection. It features the reliable ETA 2892 movement and takes it’s design inspirations from vintage watches from 1950s. The 38mm will go for $845 and the beefier 41mm will go for $945 in either a natural steel or gold pvd finish. 

This is the watch I’d wear with a nice black suit or tuxedo for a night on the town. Simple and elegant.
