MilgaussOyster, 40 mm, Oystersteel
The Oyster Perpetual Milgauss features an intense black dial with luminescent hour markers and a green sapphire crystal that gives a unique hue to the face of the watch.
With its clean lines and evocative orange seconds hand, shaped like a lightning bolt to echo the original model, the Milgauss is recognizable at a glance.


Green sapphire crystal
A secret process
The green sapphire crystal is a unique watch crystal developed by Rolex, it is scratchproof, fade-proof and available exclusively on the Milgauss.
Its light green shade, tinted throughout the entire crystal, turns nearly luminescent at the bevelled edges. The result of a secret process that required years of development to master and takes weeks to produce.
