Sea-Dweller 43mm "50th Anniversary"

This Rolex Sea-Dweller Ref. 126600, introduced in 2017 to mark the 50th anniversary of the Sea-Dweller line, is a bold and modern evolution of a professional dive watch icon. This 2024 certified pre-owned example is in excellent condition, sold as a full set, and offers a perfect mix of heritage, performance, and presence.

Crafted in Oystersteel, the 43 mm case features a black Cerachrom bezel with platinum-coated numerals, a sapphire crystal with the iconic Cyclops lens over the date, seen for the first time on a Sea-Dweller, and a striking red “Sea-Dweller” text on the dial, a direct nod to the original 1967 model.

Inside, the watch is powered by the Rolex calibre 3235, a next-generation automatic movement with 70-hour power reserve, Chronergy escapement, and COSC certification, ensuring outstanding precision and durability.

The black dial is equipped with large Chromalight-filled markers and hands that glow intensely blue in low light, providing maximum legibility. Water-resistant to an impressive 1,220 meters (4,000 feet), the watch includes a helium escape valve and Triplock crown, making it a true tool watch for deep-sea explorers.

This model is fitted with a solid-link Oyster bracelet in Oystersteel, featuring the Glidelock extension system and Fliplock extension link for a secure and adjustable fit, even over a wetsuit.

Delivered as a full set, this certified pre-owned watch includes the original Rolex box, warranty card, instruction booklet, and hang tags. It has been professionally inspected, authenticated, and cleaned by our team of watchmakers.

The Rolex Sea-Dweller 126600 “50th Anniversary” is a standout among professional divers’ watches, offering solid performance, collectability, and unmistakable Rolex identity.
