Product Features

• 42 mm Oyster case
The case is crafted from Oystersteel and features a monobloc middle case, a screw-down case back and a screw-down winding crown, providing strength, water resistance and a substantial wrist presence.

• Oystersteel construction
Rolex Oystersteel belongs to the 904L steel family. It offers excellent resistance to corrosion and is designed to retain its appearance even in demanding environments.

• Fixed 24-hour graduated bezel
The fixed bezel features clearly defined 24-hour graduations. Used together with the orange arrow-shaped 24-hour hand, it enables the wearer to distinguish daytime hours from nighttime hours.

• Second time-zone display
In addition to conventional hours, minutes and seconds, the dedicated 24-hour hand can display the time in a second time zone, making the watch especially practical for travellers.

• Independently adjustable hour hand
The conventional hour hand can be adjusted independently in one-hour increments without stopping the movement or affecting the minute, seconds and 24-hour hands. The date changes in accordance with local time.

• Date display with Cyclops lens
An instantaneous date display is positioned at 3 o’clock. The Cyclops lens over the date magnifies the numerals for improved readability.
