The BALL Engineer III Marvelight Chronometer NM9026C-S44C-TQR combines advanced construction with distinctive illumination and chronometer-certified mechanical performance. Its 40mm round case is crafted from 904L stainless steel and incorporates a Mu-metal shield, with a thickness of 13.15mm. An anti-reflective sapphire crystal protects the turquoise dial, while the solid caseback and 100-metre water resistance provide a robust foundation for everyday use and recreational water activities such as surfing and snorkeling. The turquoise dial is complemented by rainbow gas tubes on the markers and gas tubes on the hands, delivering clear night-time readability without compromising its distinctive appearance. Power comes from the automatic BALL RR1103-C calibre, which is COSC chronometer certified and provides hours, minutes, sweep seconds and a magnified date display. The watch is finished with a 904L stainless steel bracelet and folding buckle, matching the case material while completing its practical yet technically focused design.
