For many collectors, the gold standard in vintage wristwatches is, well, a vintage gold wristwatch. Whether it’s yellow or white, 14 karat or 18, gold adds instant luster to a wristwatch, elevating one’s Rolex, Seiko, or Hamilton from mere timepiece to treasured keepsake. Indeed, even as people have weaned themselves from wristwatches due to the proliferation of electronic devices fitted with built-in clocks, gold wristwatches continue to hold their appeal.
