The Universal Geneve 884100/02 maintained was produced with the same set of hands throughout its short life.
Main hour, minute hands and chronograph seconds hands are all blued steel, with baton shaped (not tapered) tritium lume. These hands may appear black in images, however this is simply due to lighting/angles, they are all blued.
The thick baton register hands, both running seconds and minute counter, are steel (not blued or painted, so silver in color), and also with baton shaped lume. In images you may see these hands appear black or white, but in all cases they are steel without additional color.
