ROLEX Milgauss Ref. 116400GV Watch

Q: What is the Rolex Milgauss Ref. 116400GV and what makes it special?
A: The Milgauss is a 40mm stainless‑steel Oyster Perpetual designed to resist magnetic fields up to 1,000 gauss. The 116400GV features the iconic orange lightning‑bolt seconds hand and a distinctive green‑tinted sapphire crystal, making it a modern classic known for its scientific heritage and everyday versatility.

Q: What does “GV” mean, and how durable is the green sapphire crystal?
A: “GV” stands for Glace Verte (green glass). It’s a scratch‑resistant sapphire with a subtle green edge unique to the Milgauss. It’s highly durable for daily wear, but like all sapphire crystals it can chip if struck hard; replacement is typically handled by authorised Rolex service centres.

Q: How anti‑magnetic is the Milgauss in real‑world use?
A: It’s engineered to withstand magnetic fields up to 1,000 gauss, using a soft‑iron inner shield and paramagnetic components (including a Parachrom hairspring). Everyday sources like laptops, phones and household magnets are unlikely to affect it. Extremely strong fields (e.g., MRI machines or industrial equipment) can exceed its rating—avoid placing the watch on or near such devices.

Q: Which movement does it use and what accuracy should I expect?
A: The Milgauss 116400GV houses the automatic Rolex Calibre 3131, a COSC‑certified chronometer. Expect accuracy around −4/+6 seconds per day when properly maintained, with a power reserve of roughly 48 hours. Routine servicing every 5–10 years is generally recommended, or sooner if timekeeping or water‑resistance concerns arise.

Q: Is it water‑resistant and can I swim with it?
A: The Oyster case is rated to 100 metres when new. On pre‑owned pieces, water resistance isn’t guaranteed without recent servicing and pressure testing. We advise avoiding swimming or showering unless the seals have been replaced and the watch has been tested. Always ensure the crown is fully screwed down before any moisture exposure.

Q: How do I wind and set the time on the Milgauss?
A: Unscrew the crown anti‑clockwise. Position 1: manual wind (about 20–30 turns if the watch has stopped). Position 2: set the time. The Milgauss has no date function. When finished, push the crown in and screw it down firmly to maintain water resistance.

Q: What are the dimensions and will the 40mm size suit my wrist?
A: The case is 40mm with 20mm lug width and a comfortable Oyster bracelet. It wears as a balanced medium size and is widely considered unisex. This example is listed at approximately 16.5 cm bracelet length; we can advise on fit and adjust the bracelet before dispatch.

Q: Can the bracelet be resized or swapped for a strap?
A: Yes. We can size the bracelet for your wrist, and additional links can often be sourced (subject to availability). The watch accepts 20mm straps; choose quality options designed for Rolex 20mm lugs and appropriate end‑links for best fit.

Q: Is the Milgauss 116400GV discontinued?
A: Yes. Rolex discontinued the Milgauss line in 2023, and the 116400GV is no longer in production. This status has reinforced its desirability among enthusiasts who appreciate its unique anti‑magnetic design and green crystal.

Q: What is included with this watch and how do you guarantee authenticity?
A: Please refer to the listing for specifics; this example is described as a 2016 piece delivered with its original box, guarantee card and documentation. A Retro Tale professionally authenticates every item, offers a 12‑month mechanical guarantee, insured DHL delivery, and a 14‑day return policy.
