Rolex's Z-Blue Milgauss is now even harder to get since being discontinued, and our 2021 example is under Rolex international warranty to March 2026. 

Retailed at Watches Of Switzerland in March 2021, this green glass, blue dial ref. 116400GV is presented fully complete from new, including its Rolex box (inner and outer), both swing tags, both booklets, Rolex international warranty card, and Watches of Switzerland extended warranty card. 

Originally developed for scientists & engineers, this extremely robust Milgauss is anti-magnetic to 1000 gauss, thanks to a shield inside the caseback that protects the movement. Powered by Rolex's self-winding calibre 3131 with 2-day power–reserve, waterproof to 100m, and fitted to the sporty Oyster bracelet, with 5mm Easylink adjustment.
