Rolex Submariner Date Two-Tone 'Serti' Dial (Ref. 16613)

This is a luxury Rolex Oyster Perpetual Date Submariner diving watch, featuring a 40mm Oyster case made of stainless steel and 18k yellow gold (Rolesor). A defining characteristic of this specific piece is the champagne or slate sunray 'Serti' dial, which is professionally set with factory diamond and sapphire hour markers rather than the standard luminous plots. The dial includes a date window at the 3 o'clock position magnified by a cyclops lens on the sapphire crystal. The watch is equipped with a unidirectional rotating bezel featuring a blue circular insert with gold-toned numerical graduations for tracking decompression stops. The construction is anchored by a two-tone Oyster bracelet with high-polish yellow gold center links and brushed steel outer links. Based on the dial configuration and case style, this model likely dates from the late 1990s to the mid-2000s. The watch appears to be in good pre-owned condition with visible micro-abrasions on the polished gold surfaces and bracelet links consistent with regular wear. The bezel insert remains vibrant with no significant chipping or fading visible, and the crown shows sharp fluting, suggesting careful maintenance. This 'Serti' (French for 'setting') variant is a rare, more formal execution of the iconic tool watch, valued for its blend of utility and luxury craftsmanship.
