Here is one of my old Rolex Explorer II this is white dial version Ref 16570 a nice all round great watch with 2 time gmt function, this comes in white dial also black dial, i always liked the Explorer 2 it has been a round a long time it is very similar to a Rolex Gmtmaster II pretty much same movement same bracelet only difference is bezel is not rotatable on the Explorer, never been as popular as the Rolex Gmtmaster II. A nice everyday hard wearing Rolex that is good value for your money in the sports range. There is a nice picture shown the night luminova on dial hour plots.
