After debuting the Submariner in the 1950s, Rolex introduced the Ref. 16618 in the late 1980s. While not the first gold version in the collection dedicated to the depths, it quickly became sought after by collectors thanks to its appealing price point and its classic case-and-bracelet design.<\/p>\n<p data-start=\"474\" data-end=\"872\">Produced until 2010, the Ref. 16618 embodies all the signature traits of Rolex\u2019s legendary diver: a 40 mm Oyster case water-resistant to 30 bar, screw-down crown, unidirectional 60-minute graduated bezel, date window magnified by the Cyclops lens, and the robust Oyster bracelet \u2014 all elevated by the luxurious use of yellow gold, making the Ref. 16618 the most opulent version of the Submariner. Over the years, Rolex produced this reference in various bezel and dial configurations. Particularly noteworthy is the version presented here, dating back to 1989, which stands out for its distinctive \u201cSerti dial,\u201d also known as the \u201cSultan dial.\u201d The dial is adorned with hour markers set with diamonds and sapphires, carefully mounted in-house by Rolex. Specifically, the baton markers at 6 and 9 o\u2019clock and the triangular one at 12 o\u2019clock are crafted from sapphires, while the remaining eight markers are set with diamonds.<\/p>\n<p data-start=\"1406\" data-end=\"1746\">This Ref. 16618 is powered by the automatic caliber 3135, recently succeeded by the updated caliber 3235. The movement is a Superlative Chronometer, meaning it has passed both the stringent COSC certification and Rolex\u2019s own in-house testing. Beating at 28,800 vibrations per hour, the 31-jewel caliber offers a power reserve of 48 hours. The watch offered here is in excellent condition and comes as a full set.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><span style=\"font-size: 16px;\">This 1989 Rolex Submariner Ref. 16618 features a 40 mm case and Oyster bracelet, both crafted in yellow gold \u2014 a hallmark of this reference. What makes this watch particularly special is its so-called \u201cSerti\u201d dial, also known as the \u201cSultan\u201d dial. Unlike other variants of the Ref. 16618, this version is adorned with hour markers made of diamonds and sapphires, meticulously set in-house by Rolex. Specifically, the baton markers at 6 and 9 o\u2019clock and the triangular marker at 12 o\u2019clock are sapphires, while the remaining eight markers are diamonds.
