This Oyster Perpetual Explorer II in Oystersteel with an Oyster bracelet features a black 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.
