Rolex has unveiled a brand new Sea-Dweller at Baselworld 2019. The last Sea-Dweller was in 2017, in celebration of the model's 50th anniversary, and was equipped with a Cyclops lens for the first time.

The new watch's overall specs remain the same, only now it carries a more luxurious two-tone Oystersteel and 18-karat yellow gold combination of materials that Rolex is calling "Yellow Rolesor." The 43mm case is waterproof to a depth of 4,000 feet and features a helium relief valve. In addition, the molded, recessed graduations and numerals on the dial are now coated with yellow gold. The Cyclops lens at 3 o’clock is there to magnify the date.

Adding contrast to the yellow and steel composition is a black dial with a gloss, satin finish. The luminescent hour markers and hands are also rendered in gold to match the case. Additionally, unlike the traditional Oystersteel version that bears "Sea-Dweller" branding in red, this edition turns out the branding in yellow gold for an added touch of luxury.

Inside, the timepiece is equipped with the automatic caliber 3235 movement, which features a precision of +2/-2 seconds per day and a power reserve of 70 hours. Finally, the watch's bracelet is a three-piece solid link with the middle portion in yellow gold secured with an Osyterlock folding clasp and Glidelock extension system.

The watch retails for 15,300 Swiss francs (approximately $15,400). Head over to Rolex’s website for more details.
