The Omega Medicus from 1939 exemplifies practical wartime design, conceived to put legibility and function first. Its distinctive Sei Tacche dial and larger case proportions accommodate a central seconds hand — a feature introduced on this Medicus line to assist in timing pulses and checks in medical contexts. Powering the watch is the Cal. 23.4 SC T3, an early Omega movement with a central seconds configuration. For the modern collector, this piece speaks to a period when utility shaped aesthetics, offering a direct connection to the instrument watches used by medical staff during the Second World War.
