A: The Milgauss is one of Rolex’s most distinctive modern tool watches, created for resistance to magnetic fields up to 1,000 gauss. Ref. 116400GV is especially recognisable for its black dial, orange lightning-bolt seconds hand and signature green sapphire crystal, giving it a sporty but unusual look within the Rolex range.

Q: What does “GV” mean?
A: “GV” stands for Glace Verte, meaning green glass. On this reference it refers to the green-tinted sapphire crystal, a feature strongly associated with the Milgauss and one of the details collectors look for most.

Q: Is the Milgauss 116400GV a good everyday watch?
A: Yes. Its 40 mm steel Oyster case, automatic movement and straightforward time-only display make it practical for daily wear. It is robust and versatile, while still feeling more distinctive than many other sport watches thanks to its scientific heritage and unusual design details.

Q: How anti-magnetic is it in real-world use?
A: The Milgauss was designed to resist magnetic fields up to 1,000 gauss, helping protect the movement from many everyday magnetic sources such as electronics and household items. As with any mechanical watch, it is still wise to avoid very strong magnetic environments or specialist equipment.

Q: Which movement does this watch use?
A: This reference is fitted with the Rolex calibre 3131, an automatic chronometer movement developed for the Milgauss. It is known for dependable everyday performance and for the anti-magnetic engineering that defines the model.

Q: Is it water-resistant, and can I swim with it?
A: The Milgauss was originally rated to 100 metres. However, with any pre-owned watch, water resistance should never be assumed without recent testing. Unless it has been pressure tested and the seals checked, it is best to avoid swimming, showering or exposing it to water.

Q: Will the 40 mm case suit most wrists?
A: For many buyers, yes. The 40 mm case is a classic, balanced size that suits a wide range of wrist sizes and offers a strong presence without feeling oversized. This particular watch is fitted on a steel Oyster bracelet sized to approximately 16.5 cm, so checking fit before purchase is advisable.

A: Yes. The Oyster bracelet can be adjusted for a better fit, and this watch is delivered with 1 extra link piece according to the product information. If you need guidance on sizing, it is best to confirm wrist measurements before dispatch.

Q: Is the Milgauss discontinued?
A: Yes. The Milgauss line was discontinued by Rolex, which has increased interest in references such as the 116400GV. Its combination of anti-magnetic purpose, green crystal and unconventional styling has helped it become a sought-after modern classic.
