Originally developed in 1956 for scientists working near electromagnetic fields, the Milgauss 116400GV pairs laboratory-grade engineering with striking design. Its green-tinted sapphire crystal and orange lightning-bolt seconds hand remain two of the most recognizable details across the entire Rolex catalogue, setting this reference apart from every other professional model in the lineup.

The 116400GV Up Close: Case, Dial and Bracelet
The 40mm case is finished with alternating brushed flanks and polished bevels, creating depth as light plays across the surface. A distinctive green-tinted sapphire crystal — exclusive to Milgauss GV references — adds a subtle emerald hue that shifts under different lighting conditions.
Inside, the black dial carries bold orange hour markers shaped like rounded rectangles, paired with the iconic lightning-bolt seconds hand in vivid orange. The result is a dial that reads quickly even in dim environments.
An Oyster bracelet with Easylink 5mm comfort extension secures the watch firmly. Explore more models in our Milgauss collection.
Movement Options: Swiss vs Japanese
Two caliber tiers let you balance performance and value:

- Japanese Automatic (Miyota) — runs at 21,600 vph with around 42-hour reserve. A proven workhorse movement offering accessible servicing and excellent day-to-day reliability.
