Featuring a 42.2mm white gold case, this reference stands out through its khaki green dial and matching composite strap. The embossed dial pattern enhances texture, while luminous numerals and hands ensure visibility in low light conditions. The date function remains positioned at 3 o’clock, powered by a reliable automatic movement engineered for precision. The sapphire crystal case back provides visibility into the movement, while water resistance supports active wear. The larger case dimensions contribute to a more contemporary wrist profile.

This model is driven by individuality. The khaki tone introduces a distinctive character rarely seen in traditional luxury watches, making it a strong choice for collectors seeking something beyond conventional dial colors.
