Pre-Loved Rolex Milgauss
The anti-magnetic Rolex built for scientists, prized for its green glass
Milgauss numbers are a fraction of Rolex's mainstream sports models, so pre-loved buyers gain access to a genuinely scarcer piece without waiting on a boutique list. Because the model sees comparatively light everyday wear among collectors, well-kept examples retain their value closely against new list price.

Why the Milgauss is iconic
Rolex launched the Milgauss in 1956 for scientists and engineers working near strong magnetic fields, its name referencing resistance to 1,000 gauss. The current reference, reintroduced in 2007, is defined by its lightning-bolt seconds hand and, on the GV variant, a distinctive green sapphire crystal.
What to pay pre-owned
Pre-owned UK prices generally run from around £5,800 to £11,500, centred near £8,000 for a full-set black-dial reference in strong condition. Complete box and papers, unpolished cases and the green-crystal GV dial variant push prices toward the top; missing documentation, heavy case polishing or worn bracelets bring it down.
Sizes & variants
References include the domed-crystal 116400 and green-tinted-crystal 116400GV, both in Oystersteel with black or white dial and orange lightning seconds hand.
How to authenticate
- 1.Verify the reference and serial number engraved on the case between the lugs against Rolex's records or a specialist.
- 2.Check the movement through a case-back inspection or service history; genuine Milgauss calibres carry Rolex's own finishing and Parachrom hairspring.
- 3.Examine the bracelet end links and clasp for correct stampings, and confirm the distinctive orange lightning seconds hand and lightning-bolt-etched crystal are original.
Guidance only — always buy from sellers offering an authentication guarantee.
Buying a pre-owned Rolex Milgauss — FAQs
What does the green crystal actually do?
It is a tinted sapphire crystal used on the GV reference for visual distinction; it has no effect on the watch's anti-magnetic function.
Is the Milgauss actually anti-magnetic in daily use?
Yes, its case and movement shield are designed to resist magnetic fields well beyond typical household electronics.
Why is it less common than a Submariner or GMT-Master?
Rolex produces the Milgauss in smaller numbers, reflecting its niche, technical positioning rather than a sports or dive focus.
