What a two-tone Explorer means in concrete terms is that the bezel crown hands applied
link dial markers and center bracelet links are made of 18k yellow
link gold. The case and outer bracelet links are steel. The Oysterlock clasp is mostly steel with a yellow gold stripe running down the center to visually match the bracelet links. This is all right in line with how Rolex typically executes two-tone
link watches from Subs to Datejusts. Nothing crazy here.
