Expanding the Aquanaut line into larger proportions, reference 5168G-001 introduces a 42.2 mm white gold case built around everyday durability and refined sport design. Power comes from the self winding Caliber 26 330 S C, delivering central seconds and date with consistent stability at 28,800 vibrations per hour. Water resistance to 120 meters, combined with a screw down crown, ensures real world usability, while the precious metal construction elevates it beyond conventional sports watches. Strong collector demand continues to follow this reference due to its balance of size, material, and modern Aquanaut identity.
