The 5168G expands the Aquanaut case to approximately 42.2mm, offering a broader dial surface and stronger visual impact. Crafted in white gold, the case maintains a balanced thickness while delivering substantial wrist weight. The blue embossed dial features luminous numerals and hands, paired with a date display at 3 o’clock. A self-winding mechanical movement ensures accuracy, visible through a sapphire case back that highlights the finishing of internal components. The composite strap, matched to the dial color, enhances both durability and comfort.

This reference is designed for those who prefer a more prominent presence. It preserves the Aquanaut identity while scaling it upward, delivering both sport functionality and a more commanding aesthetic.

Alternative / related reference

5168G-010 is the directly related alternative. It retains the 18K white-gold 42.2 mm case and the same fundamental movement architecture but changes the colorway to khaki green, including the dial and composite strap. Patek Philippe explicitly groups the 5168G-001 and 5168G-010 together as the two large-format white-gold executions.

Production-history note

Patek Philippe’s archival documentation confirms that the 5168G family was offered in midnight blue (5168G-001) and khaki green (5168G-010). The current factory technical pages specify Calibre 26-330 S C for both.
