Ball Engineer III Marvelight Auto Men's Green Watch NM9026C-S6CJ-GR | Hublot Watches, Hublot Watches for Men & Women

The Engineer III Marvelight Chronometer watch is fitted with a COSC-certified chronometer movement, the self-winding caliber BALL RR1103-C. To protect it, a mu-metal anti-magnetic shield has been selected. Mu-metal is an alloy of nickel, iron, copper and molybdenum with very high magnetic permeability, allowing it to attract and deflect static or low-frequency magnetic field lines. The use of mu-metal is a real industrial feat, capable of protecting a mechanical watch against magnetic fields up to an astonishing intensity of 1000 Gauss (or 80 000 A/m). This model includes hours, minutes, sweep seconds and an enlarged date. A screw-down crown makes it possible to offer water resistance up to 100 m/330 ft and the case is made of 904 L stainless steel for durability. Thanks to its additional amounts of chromium, molybdenum, nickel and copper, 904L steel features superior resistance to corrosion, rust and acids. The Engineer III Marvelight chronometer is now available in a variety of colors, from classic black, blue and gray to modernist green, burgundy red and ice blue.
