The Rolex Explorer II is meticulously designed to take you all around the world in classic style.
The case and bracelet are made of Rolex's Oystersteel, a proprietary 904L stainless alloy produced in their in-house foundry. 904L alloys are low-carbon steels with nickel, chromium, copper, and molybdenum. These alloys are commonly found in the aerospace and chemical industries, where their durability and corrosion-resistance are necessary for precision operations. While Oystersteel is expensive to produce and difficult to shape, it is exceptionally rugged and can take on a higher polish than other steel alloys.
The Explorer II also has an unusual 24 hour bezel, with a dedicated hand that indicates the time on a 24 hour cycle, instead of the traditional 12 hours. This 24 hour function differentiates day from night, and is a great feature for the explorers the watch is named for. A 24 hour hand is necessary for world travelers who may lose track of time zones, or for adventures where it can be hard to tell day from night, like the depths of a cave or at extreme polar regions. An independent hour hand also lets you keep track of two time zones, another great feature for travelers.
As you would expect from a Rolex, every feature of the Explorer II is crafted with care, precision, and superb quality, from the scratch-resistant sapphire crystal to the 18 carat gold hour markers on the dial. This chronometer can go anywhere that your adventures take you, crafted for superior style, reliability, and accuracy.
