The Z-Blue, explained.

The Rolex “Z-Blue” is a Milgauss variant introduced in 2014: an electric-blue sunburst dial under the green-tinted GV sapphire crystal, reference 116400GV. The vivid blue dial with the green crystal edge and orange lightning-bolt hand made it the most colourful Milgauss before the line ended in 2023.

Below: what makes the Z-Blue (116400GV) distinctive, what to verify before buying, and how it fits the Naples collector scene.

The Z-Blue took the green-crystal Milgauss and added a striking electric-blue lacquer dial, named for the “Z-Blue” colour code. Combined with the green crystal tint and the orange lightning-bolt seconds hand, it is the boldest expression of the modern Milgauss.

It shares the 116400GV reference and the antimagnetic soft-iron shield; only the dial sets it apart from the black-dial GV.

What to verify


Checking a Z-Blue before you buy.

  • Confirm the electric-blue sunburst dial under the green-tinted crystal.
  • Check the orange lightning-bolt seconds hand and antimagnetic case.
  • Note it shares the 116400GV reference with the black-dial GV — the dial is the difference.
  • Verify a 2014–2023 serial; the Milgauss is discontinued.

The Z-Blue, answered.

What is the Z-Blue Milgauss?

Does the Z-Blue have the green crystal?
