Rolex Explorer II 42mm 226570 Watch

The Rolex Explorer II 226570 is one of the most distinctive models in the brand’s Professional watch collection, designed around exploration in demanding environments and clear, practical timekeeping. Its 42 mm Oystersteel case, fixed 24-hour graduated bezel and prominent orange 24-hour hand form the signature visual identity of the Explorer II, while delivering the robustness, legibility and functionality required for everyday wear. Available with a white or black dial, the watch takes on a different character with each option while retaining the bold, purposeful tool-watch aesthetic that defines the Explorer II.

Product Features

• 42 mm Oystersteel Case

The 226570 features a 42 mm Oyster case crafted from Rolex Oystersteel. Its monobloc middle case, screw-down case back and screw-down winding crown create a robust and reliable construction, with water resistance to 100 metres. Oystersteel belongs to the 904L steel family and offers excellent resistance to corrosion while maintaining a refined surface finish. The 42 mm dimensions reinforce the Explorer II’s Professional watch character and provide a spacious, highly legible setting for the dial and 24-hour display.

• Fixed 24-Hour Graduated Bezel and Orange Hand

The fixed 24-hour graduated bezel is one of the Explorer II’s most recognizable design elements. The distinctive orange arrow-shaped 24-hour hand travels around the dial once every 24 hours and points to the corresponding graduation on the bezel, allowing the wearer to distinguish clearly between daytime and nighttime hours. Under normal conditions, the display can also be combined with the independently adjustable hour hand to indicate a second time zone, providing practical functionality for travel, cross-time-zone work and everyday situations requiring simultaneous reference to two local times.

• Highly Legible Dial and Chromalight Display

The 226570 is available with either a white or black dial, with both versions designed to prioritize immediate readability. Prominent hour markers, broad hands and the orange 24-hour hand create a clear visual hierarchy, allowing different time indications to be distinguished at a glance. The hands and hour markers feature a Chromalight display that emits a long-lasting blue glow in dark conditions, continuing the Explorer II tradition of emphasizing legibility in low-light and demanding environments.

• Date Display and Cyclops Lens

A rapid-setting date display is positioned at 3 o’clock, while the Cyclops lens on the scratch-resistant sapphire crystal magnifies the date for easier reading. The durable sapphire crystal combines excellent resistance to scratches with visual clarity, allowing the date function to integrate naturally into the dial while adding everyday practicality to the watch’s professional tool-watch design.

• Calibre 3285 Self-Winding Movement

The watch is powered by the Rolex-manufactured calibre 3285, a self-winding mechanical Perpetual movement providing central hour, minute and seconds hands, a 24-hour display, second time-zone functionality, an instantaneous date and stop-seconds for precise time setting. The hour hand can be adjusted independently in rapid one-hour increments without affecting the minute, seconds or 24-hour hands, making time-zone changes particularly convenient when travelling.

The movement incorporates a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, enhancing stability when exposed to magnetic fields, temperature variations and shocks. Its bidirectional self-winding system uses a Perpetual rotor to wind the movement and provides a power reserve of approximately 70 hours, offering additional convenience even when the watch is set aside for a weekend.

• Oyster Bracelet

The three-piece solid-link Oyster bracelet creates a balanced and substantial proportion with the 42 mm case, reinforcing the watch’s sporty, professional character while providing the stability and comfort required for extended wear. Crafted from Oystersteel, the bracelet is fitted with an Oysterlock folding safety clasp designed to help prevent accidental opening.

The Easylink comfort extension link allows the wearer to increase the bracelet length by approximately 5 mm without tools. This provides greater flexibility when wrist size changes slightly due to temperature or activity, helping the Explorer II maintain a comfortable fit across travel, outdoor activities and everyday wear.

Summary

The Rolex Explorer II 226570 combines the heritage of a purpose-built exploration watch with the demands of modern everyday use. Its 42 mm Oystersteel case, fixed 24-hour graduated bezel, orange arrow-shaped 24-hour hand and Chromalight display create an instantly recognizable appearance, while the second time zone, date display, approximately 70-hour power reserve and Easylink comfort extension system ensure that these design elements are matched by genuine everyday functionality.

Rather than relying on elaborate decoration, the Explorer II draws its appeal from clarity, robustness and a distinctly functional design. The white dial delivers striking visual contrast, while the black dial offers a more understated and cohesive professional appearance. Both retain the signature orange 24-hour hand and unmistakable tool-watch character of the Explorer II. For those seeking a distinctive Rolex Professional watch capable of transitioning naturally between travel, outdoor activities and everyday wear, the 226570 offers a compelling combination of practical functionality, wearing versatility and enduring design.
