The 1961 Junghans collaboration eliminated decorative numerals in favor of radical radial proportion and pure linework. Our teardown examines the unpolished case bevels and movement calibres defining early production runs.
Original convex acrylic crystals preserve the optical clarity intended by the Ulm school, pairing surgical legibility with slender baton hands.
Movement and case maintenance
Essential technical field notes covering mechanical movement conservation, factory acrylic crystal preservation, and authentic dial degradation standards for active collectors.
Calibre lubrication cycles

Tritium degradation markers
Synthetic horological oils degrade after five years regardless of runtime. Analyzing friction points, pallet fork escapements, and amplitude variances in manual-wind calibres.
Polywatch versus replacement: retaining factory tension-ring crystals protects dial seals while maintaining original refraction profiles across stepped Bauhaus bezels.
Differentiating stable atmospheric patina from moisture breakdown. Radiometric analysis and macro photography expose modern reluming attempts on unpolished collector references.
