Rolex Milgauss Z Blue Watch
Ever since the original Milguass — a watch that dates back to 1956 — engineers and technicians have counted on it for its reliability, thanks in part to an internal magnetic shield that protects its movement. It's since been updated repeatedly, and in its latest iteration, the Rolex Milgauss Z Blue Watch it receives an electric blue face to complement its green sapphire crystal. Featuring a 40mm oyster case, the watch is waterproof down to 100 meters, and sports a hermetically-sealed screwed-down case back. The oyster case provides further protection for its self-winding mechanical movement, while the oyster bracelet gives you a secure and comfortable fit any time you wear it.
