The next step in chronometer evolution: Zeitmeister, the only wristwatch chronometer that is presently certified according to the German industrial norm. As a sign of its uniqueness, the back of each watch in this new collection is adorned with a relief engraving of Glashütte Observatory, where our models undergo a rigorous, 15-day testing procedure to verify that they indeed keep time with to-the-second precision. Only after passing these tests do they earn the right to adorn themselves with the official chronometer certificate.
