Name: Patek Philippe Aquanaut "Khaki Green" 5168G-010
Brand: Patek Philippe
SKU: 5168G-010

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.

What it is

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.

Buying notes

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.

Market read

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.

Service expectations

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.

Authentication

The Aquanaut 5168G Khaki Green is a high-value white gold reference with premium secondary market pricing; the embossed dial pattern regularity and 18k white gold hallmarks are the primary authentication anchors.

Known issues in the market

Limited production and strong secondary market demand create price pressure that attracts misrepresentation; documentation (box, papers, extract de registre) is important for this reference.
The embossed "checkerboard" pattern on the khaki green rubber dial must be precise and regular; uneven or shallow embossing indicates a non-genuine dial.
White gold case must have 18k hallmarks; the 5168G is white gold only, not stainless steel; a steel case claiming to be white gold is immediately detectable by weight and hallmark.
Fold-over rubber strap clasp should bear "Patek Philippe" engraving and operate crisply without flex in the clasp body.
Gyromax balance wheel is visible through the sapphire caseback; a standard lever-balance wheel without the characteristic Gyromax eccentric weights indicates a wrong movement.

Area	What to check	What is correct	Red flag
dial	Khaki green rubber embossed pattern	Regular rectangular embossed pattern; even depth and spacing across the full dial surface; khaki (olive) green color consistent across the dial; no fade or color variation within the dial	Uneven embossed pattern with varying depths; bright or yellow-tinted green (incorrect color); any sections where the pattern appears shallow or absent
case	White gold case and hallmarks	18k white gold; "750" hallmark on caseback; slightly heavier feel vs. steel for the same size (white gold is denser); cool grey-white color without yellow warmth; 42.2mm diameter	Missing "750" hallmark; lighter weight inconsistent with 42.2mm white gold case; warm or yellow tone (steel or yellow gold, not white gold); case diameter outside 42.0-42.4mm
movement	Cal. 324 S C Gyromax balance via caseback	Sapphire caseback shows Cal. 324 S C; Gyromax balance wheel with four eccentric gold weights visible; "PATEK PHILIPPE GENEVE" on movement; date mechanism at 3; "324 S C" text	Standard non-Gyromax balance wheel (uniform rim, no eccentric weights); Cal. 324 S C text absent; non-Patek movement; solid caseback on claimed exhibition variant
bracelet	Rubber strap and fold-over clasp	Khaki green rubber strap with embossed pattern matching the dial; fold-over white gold clasp with "Patek Philippe" text; clasp snaps closed crisply with no flex	Strap color mismatch to dial; clasp without "Patek Philippe" engraving; clasp flex or rattle when operated; strap embossing that does not match the dial pattern
case	Aquanaut octagonal case shape	Rounded octagonal case with eight sides; polished bezel with brushed case body; integrated rubber strap attachment is flush; crown at 3 with correct Patek pattern	Circular case (not octagonal); fully polished case body (should have brushed sections); visible gap between strap and case attachment

Common legitimate replacements

Rubber straps are the most commonly replaced component; Patek Philippe replacement straps for the 5168G are available through authorized dealers.
Clasp replacement is possible and should be confirmed as matching white gold with correct Patek engraving.

Authentication guide

Last reviewed June 2026

The 5168G-010 pairs a white gold case with a khaki green dial and matching composite strap. The green dial hue is highly specific and difficult to replicate; the white gold case adds a complication not present in the more common steel Aquanaut references.

Known reproduction risks

toggle

HIGH RISK

Replica Aquanaut watches in the khaki green configuration, often using incorrect green tones and shallow dial embossing.

Green dial tone that is too vivid or too brown compared to the specific khaki hue of genuine 5168G-010 examples
Embossed octagonal grid that is shallow or fades near the edges
Crown at 9 o'clock rather than the correct 4 o'clock Aquanaut position
Exhibition caseback showing a non-Patek movement architecture
White gold case that does not have the correct warmth or luster distinct from steel

Dial variants by era

Era	Description	Identifiers
2018 to present (standard production)	White gold case with khaki green embossed dial and green composite rubber strap.	Khaki green embossed "Tropical" pattern dial -- the embossing is an octagonal grid texture specific to the Aquanaut The green hue is distinctly earthy khaki, not vivid green, not olive-brown Applied "Patek Philippe" text in the upper dial zone Calatrava cross at 12 applied, three-dimensional Luminescent applied indices in the Aquanaut elongated baton style Date window at 3 o'clock

Service part flags

toggle

Dial

Original: Khaki green Aquanaut embossed "Tropical" texture. The octagonal grid embossing runs from edge to edge with consistent depth and no fade near the indices or date aperture.

Replacement tells

Green tone that appears too vivid or saturated -- the khaki green is deliberately muted and earthy
Embossed octagonal grid that is shallower near the dial edges or the date window
Applied "Patek Philippe" text that does not cast a shadow under raking light

Composite strap

Original: Patek's proprietary composite rubber strap in matching khaki green, with fold-over safety deployant. The strap material has a specific matte texture and consistent color throughout.

Replacement tells

Strap color that does not precisely match the dial green -- even subtle mismatches indicate a non-factory strap
Generic rubber strap without the correct Aquanaut tread-pattern cutout on the strap surface
Deployant clasp without correct Patek engraving

Crown

Original: Crown at 4 o'clock on the Aquanaut -- different position from the Nautilus at 9 o'clock. This is a defining visual difference between the two families.

Replacement tells

Crown at 9 o'clock indicates a Nautilus, not an Aquanaut
Crown without Patek coin-edge profile or with incorrect diameter

Case back markings

2018 to present

Exhibition caseback displaying Cal. 324 S C self-winding movement
Gyromax balance wheel and Cotes de Geneve bridges visible through the caseback
"Patek Philippe" on the movement plate
Reference 5168G-010 and serial number on the case flank
18K white gold hallmark (750 fineness stamp)

Movement tells

toggle

Cal. 324 S C is a self-winding movement with seconds and date. The same caliber platform appears across several Patek sport references; movement finishing quality is the key authentication differentiator.
Gyromax balance wheel with four gold weights should be visible through the exhibition caseback. Free-sprung design means no regulator spring contacts the hairspring.
Cotes de Geneve striping on the bridges should be parallel and uniform under magnification. Wavy or uneven striping indicates a service-reassembly quality issue.
Date advances with an instantaneous jump at midnight. A creeping date advance indicates a worn date mechanism.
Geneva Seal is stamped on the movement bridges; request confirmation at any professional service.
