The Rolex Sea-Dweller Ref. 126600, also known as the “Red Letter,” is a standout in the world of Rolex sport watches. With its bold 43mm case, black dial, and the iconic single line of red text, this piece nods to vintage Sea-Dweller heritage while packing modern performance. Powered by an automatic movement and water-resistant to a serious 1,220 meters, it’s built for deep-sea use but looks just as sharp on land. This 2019 pre-owned example fits up to a 7.75-inch wrist and comes with the original box and international warranty card. Light scratches are present but nothing major.
