Rolex Explorer II, 40mm, Calibre 3185, automatic, chronometer-certified, 16570 D-serial

The Rolex Explorer II 16570 White Dial, widely known as the “Polar”, combines a 40mm stainless steel Oyster case with a distinctive white dial, black-surrounded hour markers and a red 24-hour hand. Its fixed steel 24-hour bezel and restrained proportions give this discontinued reference a practical, understated character. This D-serial example dates to circa 2005–2006, offering the familiar five-digit Rolex sports-watch design with useful everyday functionality.

Inside is the Rolex Calibre 3185, a self-winding, chronometer-certified movement with a date display and independently adjustable local-hour hand. This allows the wearer to change local time without stopping the watch or disturbing the minutes, while the red 24-hour hand maintains a reference time against the bezel. It is a useful arrangement for travel, combining straightforward operation with the established appeal of Rolex’s mechanical GMT movements.
