Steinhart has joined the semi-in-house movement crowd such as Dornblueth and Nomos (And even Panerai’s base movements for that matter) with some heavily modified and customized versions of the ETA Handwound Unitas movements that are so popular. Announced on their 10th Anniversary, these movements are very cool, with customized ratchet wheels, 3/4 bridges, swan neck regulator as well as a beautiful screw balance – all very German in their production.
