NOMOS Glashütte Ludwig 38 Reference No.: 234 Also in a more modern size of 38 millimeters, this watch speaks Latin-or at least looks as if it could, and this quickly rubs off on the wearer: Ludwig 38 with its Roman numerals expands our great new range of 38 millimeter models. You can watch the manual winding Alpha movement, which was built in-house in Glashütte, ticking away through the sapphire crystal glass back. It's a pleasure-every day.
