Ball Engineer III Marvelight Automatic Watch with Blue Dial.
Engineer III is the modern interpretation of the Engineer, combining 904L steel, mu-metal magnetic protection, and the Amortiser system in cases sized for daily wear. The Marvelight presents the Engineer III in its simplest form, displaying hours, minutes, sweep seconds, and an enlarged date. Its 904L stainless steel contains chromium, molybdenum, nickel, and copper for increased resistance to corrosion and acids. The case measures 40 mm in diameter and 13.15 mm thick.
The Ball RR1103-C is a COSC-certified chronometer. The hands and indices are continuously lit by 14 sealed glass tubes of tritium gas, each self-powered for 25 years. Magnetic protection reaches 80,000 A/m — 1,000 Gauss. This protection is provided by an inner case of mu-metal, an alloy of nickel, iron, copper, and molybdenum that directs magnetic field lines around the movement.
The 14 tubes contain tritium gas, which emits light continuously through radioactive decay using its own energy. Tritium has a half-life of 12.3 years, so the glow gradually fades. Ball rates the tubes for at least 25 years of useful legibility.
The Contrôle Officiel Suisse des Chronomètres tested the movement for 15 days in 5 positions and at 3 temperatures. Certification requires an average daily rate between -4 and +6 seconds. The certificate covers the movement as tested, before it was cased.
80,000 A/m is equivalent to 1,000 Gauss, which covers the magnets encountered in everyday use — speaker surrounds, laptop and tablet closures, handbag clasps, induction cooktops. An inner case of mu-metal, an alloy of nickel, iron, copper and molybdenum, directs magnetic field lines around the movement.
It is a steel with more chromium, molybdenum, nickel, and copper than the 316L used in most watch cases. It offers greater resistance to corrosion and acids and takes a deeper polish. It is also harder to machine, which is why few makers use it.
Yes. It threads into the case and compresses its gasket to maintain water resistance. Unscrew it to set the time, and screw it back down before exposing the watch to water.
