Rolex 116400GV (Pre-owned - Good) — USD 16,824 on eBay

The Rolex Milgauss reference 116400GV is distinguished by its green sapphire crystal, a unique feature within the Rolex catalog. This specific crystal, denoted by "GV" for "Glace Verte," provides a subtle green tint to the edge of the crystal, setting it apart from other Milgauss models and the broader Oyster Perpetual line. The model was introduced as part of the reintroduction of the Milgauss, a line originally designed for scientists and engineers working in environments with strong magnetic fields. Its design elements, including the lightning-bolt second hand and specific dial markers, reinforce its technical heritage. The watch features a 40mm Oyster case crafted from 904L stainless steel, known for its high corrosion resistance. It houses the automatic caliber 3131, an in-house movement developed by Rolex, which incorporates paramagnetic components to enhance its resistance to magnetic fields up to 1,000 gauss. The movement provides a power reserve of approximately 48 hours. The watch is fitted with a smooth bezel and is water-resistant to 100 meters, secured by a screw-down Twinlock winding crown. The green sapphire crystal is a defining characteristic of this particular reference. This reference appeals to collectors interested in Rolex's technical watches and those who appreciate distinctive design elements. The green sapphire crystal is a key differentiator, offering a visual signature not found on other Rolex models. The black dial variant, often paired with the green crystal, provides a contrast that highlights the crystal's unique properties. The Milgauss line, with its focus on anti-magnetic properties, occupies a specific niche within Rolex's professional watch offerings, attracting those who value both its technical capabilities and its unique aesthetic.
