Verdict
Choose the Explorer if you want the most distilled, wearable tool watch Rolex makes — slim, symmetrical, and quietly perfect. Choose the Explorer II if you want a bigger watch with a date, a distinctive 24-hour function, and the option of the striking Polar dial. The Explorer is the purist's pick; the Explorer II does more and wears larger.
Comparison FAQ
The Explorer is a time-only 36 mm field watch; the Explorer II is 42 mm and adds a date, a fixed 24-hour bezel, and a 24-hour hand for distinguishing day from night. The Explorer II also offers a white 'Polar' dial.
On modern versions, effectively yes — the local hour hand is independently adjustable, so the 24-hour hand and bezel can track a second time zone. The original 1655 had a fixed 24-hour hand used only as a day-night indicator.
The Explorer II is larger, at 42 mm versus the Explorer's 36 mm.
