Datejusts in white gold are very rare birds. And when they come with the beautiful glossy, black gilt dial they really make incredible watches. They were mostly ref 1601, although very few sapphire crystal ref 16019 do exist. Here is a beautiful example from 1961, featuring a mint MKI tightly fluted bezel.

Case – 18K white gold, fluted bezel, excellent condition.
Movement – Automatic, Rolex caliber 1560, butterfly rotor.
Dial – Black gilt, rhodium background, flawless.
Band – Black shell cordovan strap.
