Rolex 6827 (Pre-owned - Good) — USD 13,490 on eBay

The Rolex Datejust reference 6827 represents the brand's Medium series iteration of the Datejust model line. This 31mm variant was produced during the 1970s and 1980s, positioning it as a mid-sized option within the Datejust collection during that period. The watch features a 31mm yellow gold case paired with a smooth bezel and acrylic crystal. Water resistance is rated to 100 meters. The timepiece houses the automatic caliber 2135 movement, which provides a 42-hour power reserve when fully wound. This reference appeals to collectors seeking a vintage Datejust in precious metal with the distinctive proportions of the Medium series. The yellow gold case material and production era make it relevant for those focused on Rolex's precious metal offerings from the 1970s-1980s period. The 31mm case size places it between contemporary smaller and larger Datejust variants of its production timeframe.
