A luxury dive watch featuring a solid 18K yellow gold Oyster case and bracelet, paired with a iconic black dial and unidirectional rotatable Cerachrom bezel with gold numerals. The Submariner 116618LN is powered by Rolex’s in-house Caliber 3135 automatic movement, COSC-certified as a Superlative Chronometer, offering -2/+2 sec/day precision. Luminous Chromalight hour markers and Mercedes hands ensure optimal legibility in low light. The scratch-resistant sapphire crystal and helium escape valve (on some variants) underscore its professional diving heritage—rated to 300m (1000ft). The watch includes a date window at 3 o’clock with Cyclops magnifier, and the ‘Submariner’ text, depth rating, and ‘Swiss Made’ inscriptions are clearly visible on the dial. Its robust construction, timeless design, and exceptional craftsmanship make it a coveted icon among collectors and enthusiasts. Ideal for formal events, business settings, or upscale casual wear—equally at home on a yacht as in a boardroom. The gold finish exudes opulence while retaining the tool-watch ruggedness that defines the Submariner lineage.
