===CERN silver non-lume===

[[File:Ref 1019 cern-dial.webp|thumb|right|320px|alt=Silver CERN non-lume 1019 — silver dial with black-infilled hand interiors, no tritium plots at the indices, foot text "T SWISS T" despite the dial carrying no actual tritium. Image via Monochrome.|Silver CERN non-lume 1019 — silver dial with black-infilled hand interiors, no tritium plots at the indices, foot text "T SWISS T" despite the dial carrying no actual tritium.

Silver dial with black-infilled hand interiors and no tritium plots at the indices. Foot text reads "SWISS" (earliest production) or "T SWISS T" (later production); the latter has been read by some collectors as a Rolex catalogue inconsistency given that the dial carries no actual tritium regardless of the marking. The practical reason for the lume omission is documented in the [[Reference:milgauss#CERN provenance|hub's CERN section]]: tritium plots produce scintillation background that disturbs low-statistics measurements, and removing the plots removes the failure mode.
