The 5168G khaki dial in white gold has proven one of the most tradeable Aquanaut variants; secondary prices hold a substantial premium over the roughly $36,000 retail price.
The 5168G-010 is the Aquanaut in 42mm white gold with a khaki green dial and matching composite strap, introduced at Watches & Wonders 2021. White gold mutes the case's flash in a way yellow or rose gold does not, letting the dial color carry the watch. Collectors care because the khaki green became a reference point for the broader industry's green dial moment, and Patek kept supply tight enough that demand has never caught up.
Patek introduced the 5168G in 2021 as part of the Watches & Wonders Geneva debut, a significant platform for the reference given the event's prestige. The caliber is the 324 S C, a self-winding movement with a peripheral rotor and date display at 3 o'clock. The 42mm case size positions it as the larger Aquanaut sibling to the 5167 (38mm), and white gold keeps it in the precious-metal tier alongside the 5167R and 5167A alternatives.
The khaki colorway has not been replicated in other Aquanaut metals, making the 5168G-010 the only way to get this specific combination from Patek. Production remains limited and the reference has not appeared in large quantities at authorized dealers since launch.
Verify the composite strap is original. Aftermarket straps exist in quantity, and some sellers swap them without disclosure. The strap color should match the dial precisely; fading or mismatched hue on a lightly worn example is a red flag.
Check the crown and pushers for wear consistent with the stated age, since white gold shows handling marks differently than steel. Confirm the box and papers are present and dated to the purchase year, as the secondary market commands significant premiums and documentation is expected. A independent pre-purchase inspection by a Patek-experienced watchmaker is worth the cost given the price point.
The 5168G-010 trades at a substantial premium to retail. As of mid-2026, secondary market prices have settled in the $80,000 to $100,000 USD range depending on condition and completeness, against a retail reference price in the low $50,000s. The white gold case and limited supply both push the premium higher than steel Aquanauts.
The green dial trend cooled somewhat after 2022, but the 5168G held its floor better than many green-dial releases from other brands because Patek's supply discipline is real, not manufactured scarcity.
The 324 S C is due for service every 3 to 5 years under active wear, or longer for a watch worn occasionally and stored properly. Patek Philippe factory service for the 5168G runs approximately $2,000 to $3,500 USD depending on what work is required, and factory service is strongly recommended given the white gold case finishing. Keep service records, as gaps in documentation affect resale.
