A luxury timepiece featuring Rolex's iconic Submariner design in solid 18K yellow gold with a vibrant blue dial and matching blue ceramic bezel insert. The watch displays the classic Mercedes-style hour hands, luminous hour markers, and a date window at 3 o'clock with Cyclops magnifier. Text on the dial reads 'SUBMARINER', '1000ft = 300m', 'SUPERLATIVE CHRONOMETER OFFICIALLY CERTIFIED', and 'SWISS MADE'. The unidirectional rotating bezel has white numerals and markings for diving timing, while the Oyster Perpetual case ensures water resistance up to 300 meters. Paired with a matching 18K gold Oyster bracelet with Glidelock clasp, this model exemplifies precision engineering, robust construction, and timeless elegance. Ideal for formal events, business settings, or as a statement piece for collectors and connoisseurs of horology. Its high-polish and brushed finishes create dynamic light play, enhancing its luxurious presence on the wrist. The automatic movement (Caliber 3235) offers ±2 sec/day accuracy and 70-hour power reserve. This is not a smartwatch but a mechanical chronometer certified by COSC.
