Explorer II

Oyster, 42 mm, Oystersteel

This Oyster Perpetual Explorer II in Oystersteel with an Oyster bracelet features a white dial with an arrow-shaped 24-hour hand and hour markers in Chromalight.

Its highly legible dial, extremely resistant Oystersteel and waterproofness have made it the watch for the extremes.

24-Hour Bezel

Reliability in the toughest conditions

The Explorer II is equipped with an additional 24-hour display; a dedicated hand circles the dial in 24 hours rather than the usual 12, pointing to a fixed bezel with 24 hour graduations.
