Key Features

• Stainless Steel Case and Oyster Bracelet: The 44mm round case and integrated Oyster bracelet are forged from high-grade stainless steel, offering exceptional strength and resistance to saltwater corrosion. This robust construction ensures the watch maintains its integrity and appearance even after prolonged exposure to underwater pressures and harsh conditions.
• Unidirectional Rotating Bezel with Black Top Ring: The bezel is engineered for safety and precision, rotating only in one direction to prevent accidental overestimation of dive time. Its black top ring enhances contrast and readability, especially in low-visibility underwater settings, allowing divers to track elapsed time with confidence.
• Black Dial with Luminous Hands and Markers: The analog black dial features highly legible luminous hands and dot hour markers, ensuring visibility in dark or murky waters. Minute markers along the outer rim provide additional reference points for accurate timekeeping during critical dive phases.
• Date Display at 3 O’Clock: A practical date window is positioned at the 3 o’clock location, offering everyday utility without disrupting the dial’s balanced design. This feature adds functional value for both professional and personal use.
• Automatic Movement: Powered by a self-winding mechanical movement, the watch delivers consistent and accurate timekeeping without reliance on batteries. This traditional yet advanced mechanism is a hallmark of Rolex’s engineering excellence.
• Scratch-Resistant Sapphire Crystal: The crystal covering the dial is made from synthetic sapphire, renowned for its exceptional hardness and resistance to scratches. It protects the dial from impacts and abrasions, preserving clarity and legibility over years of use.
• Screw-Down Crown and Solid Case Back: These critical sealing components ensure the watch’s internal mechanisms remain protected from water and pressure at extreme depths. The screw-down crown must be properly tightened after use to maintain water resistance.
• Oysterlock Clasp: The secure folding Oysterlock clasp prevents accidental opening, providing peace of mind during active use. It is designed for comfort and reliability, even when worn over a wetsuit or dive gear.
