The Engineer III Marvelight Chronometer reveals a perfectly balanced design promenading elegance while appearing quite sporty at the same time. The RR (âRailRoadâ) monogram stands out delicately at the end of the seconds hand and subtly recalls BALLâs railroad heritage. The Marvelight Chronometer is available in a variety of colors, from the classic black, blue and grey to the modernist green, red and ice blue. The dial has voluntarily been kept as plain as possible, with the attention going directly to the wide gas tubes. Allowing a peerless night reading, the tubes provide superior luminosity that is about 100 times brighter than the conventional luminous. This state-of-the-art Swiss technology consists in encapsulating H3 gas in glass microtubes. Light energy is released when the H3 molecules strike the internal colored surface of the tubes, without requiring recharge from any outside light or energy source. This model is provided with a COSC certified chronometer movement, the automatic caliber BALL RR1103-C. To protect it, a mu-metal anti-magnetic shield has been selected in order to attract and deviate magnetic field lines up to an astonishing intensity of 1,000 Gauss. A screwed-in crown allows a water resistance up to 100 meters and the case is made of 904L stainless steel for higher durability.
