This the elegant lines of this early-1950s Veri-Thin captures everything I love about the Gruen’s post-war design language. Inside, Gruen’s caliber 423 manual movement keeps the profile thin. Gruen movements from this era are simple but beautifully engineered and consistent. With nothing more than a basic service, this one still delivers reliable, accurate timekeeping after 3/4 of a century.
