Rolex 40mm Sport Automatic Watch | Swiss Luxury for Diving, Swimming & Outdoor Adventure

Rolex — Born for the Water, Built for Every Adventure

The Rolex 40mm sport automatic watch traces its heritage directly to the Oyster — the world’s first waterproof wristwatch, introduced in 1926. Today, that pioneering spirit lives on in a case that’s water-resistant to 100 metres, sealed by a screw-down Twinlock crown and protected by a scratch-resistant sapphire crystal. Whether you’re diving, swimming, sailing, or simply living life at full pace, the COSC Superlative Chronometer-certified self-winding movement keeps perfect time within +2/-2 seconds per day with a ~70-hour power reserve — no matter the conditions.
