Yes, it’s the 16550 made from roughly 1984 to 1989, and offered in both black and white dials.
The early white dials had white gold hands and hour markers. This made for poor legibility, so Rolex soon started making the white dial with the hands and hour markers painted black.
Some of the white dial versions (in both hand/marker configurations) turned cream over the years, but many, not all, collectors regard the white gold hand/marker version as the true cream dial Explorer II 16550.
The black dial version had white gold hands and markers for the duration of the run.
