The Patek Philippe Aquanaut 5164G-001 is the Travel Time variant of the Aquanaut collection, housing a dual-time-zone complication in an 18K white gold case measuring 40.8mm in diameter. Within the Aquanaut lineup it occupies a distinct position: more complicated than the time-only 5167, more wearable and sporty than the Calatrava Travel Time references, and finished in a precious metal that elevates it well above steel siblings.
This review is written from the dealer desk — from handling, inspecting, buying, and selling the 5164G-001 repeatedly. We will cover what the specifications mean on the wrist, how this reference moves at the market level, what to check before handing over six figures, and whether the asking price of $172,474 for a brand-new, full-set example reflects where this watch genuinely sits today.

What the specs mean on the wrist
The 40.8mm white gold case is the first thing to understand in ownership terms. White gold reads cooler and more formal than the steel or rose gold variants, yet the Aquanaut's rounded octagonal bezel and rubber strap keep it from ever feeling like a dress watch. At just under 41mm it sits well on a broad range of wrist sizes — not overwhelming on a 7-inch wrist, and appropriately substantial on larger ones. The integrated rubber strap is central to the Aquanaut's identity: Patek engineers it specifically for this case, and it wears far more comfortably through a long travel day than any bracelet would. White gold also adds meaningful heft compared to steel, so you feel the watch, which most buyers at this level actually appreciate.
The automatic movement powering the 5164G-001 drives a Travel Time complication — a local-time and home-time display controlled by pushers integrated into the case flanks. In practical use it is one of the most intuitive dual-time executions in fine watchmaking: a single press advances or retires the local hour hand in one-hour increments without disrupting the running seconds or minute track, so you are never resetting the watch in a taxi from the airport. The blue embossed dial — Patek's signature tropical-pattern texture across the Aquanaut family — is highly legible and pairs naturally with the white gold case, producing a cooler, more graphic look than the same dial in yellow or rose gold.
The dealer’s take
At the dealer level the 5164G-001 is one of the more consistently requested white gold Aquanaut references. The Travel Time complication broadens the audience beyond pure sports-watch collectors: we see demand from frequent international travelers, executives who want one watch that covers two time zones without complexity, and collectors who already own a 5167 and want to step up in both metal and complication. White gold commands a premium over stainless steel across the Aquanaut range, and brand-new, full-set examples are genuinely scarce in the secondary market — Patek's authorized dealer allocation on complicated white gold references is tightly controlled, which is part of why a brand-new example with box and papers commands the price it does.
Value retention on white gold Aquanaut complications has historically been robust, and the 5164G-001 is no exception. We do not quote specific resale percentages because this market moves, but the combination of precious metal, a practical complication, an iconic case design, and Patek provenance means this reference does not sit long when it arrives at the right price. Buyers who come to us for the 5164G-001 are rarely bargain-hunting — they have usually already decided on the reference and are looking for condition confidence and paperwork integrity, which is exactly where a reputable dealer adds value over a private transaction.
What to check before you buy a Aquanaut
- Case and bezel condition in white gold: White gold shows polishing more readily than steel. On a pre-owned example, inspect the bezel flanks and lug edges closely for over-polishing that rounds off the originally crisp lines. A brand-new example should have factory-sharp edges throughout, but confirm no handling scratches have been introduced to the bezel or case sides before you accept the piece.
- Pusher and crown function: The Travel Time complication relies on the two lateral pushers to advance and retire the local hour hand. Test both pushers multiple times to confirm they click cleanly and the local hour jumps crisply in both directions without hesitation or drag. Stiff or mushy pushers can indicate moisture ingress or a service need.
- Rubber strap and deployment clasp authenticity: The integrated rubber strap is a known target for aftermarket substitution. Verify the strap is the correct Patek-supplied unit — check the embossed pattern alignment, the tang or deployment clasp engravings, and confirm the strap reference matches what is documented. A replacement strap, even a high-quality one, affects originality and resale value.
- Box, papers, and reference matching: At $172,474 the paperwork is not optional. Confirm the reference number and serial number on the Extract from the Archives or warranty card match the case back engraving exactly. Review the purchase receipt or dealer invoice, check the inner and outer box integrity, and verify all hangtags and booklets are present — full-set documentation on white gold Aquanaut complications is a material part of the asset's value.
Who the 5164G-001 is for
The 5164G-001 is built for the buyer who wants Patek's sporting aesthetic with genuine precious-metal refinement and a complication that earns its place in daily life. It suits the frequent traveler who crosses time zones regularly, the collector who finds steel Aquanauts too understated for formal occasions but finds dress watches impractical, and the buyer who wants a single watch that covers both a boardroom presentation and a weekend boat trip without apology. It is not the right choice for someone who primarily wants a field-wearable beater or who is buying purely as a financial instrument — this is a watch to be worn and appreciated.
Alternatives worth considering
- Patek Philippe Aquanaut 5167A-001 (Steel, Time Only) — The logical comparison for buyers questioning whether the Travel Time complication and white gold premium are worth it. The 5167A in steel is the pure, distilled Aquanaut — simpler, lighter on the wrist, and lower entry price — making it the first cross-shop when budget or complication utility is in question.
- Patek Philippe Aquanaut 5164R-001 (Rose Gold Travel Time) — Same complication and case architecture as the 5164G but in 18K rose gold with a khaki-brown dial. Buyers who want warmth in the metal and a slightly more casual dial color often end up here; the two references compete directly, and the choice typically comes down to personal color preference.
- Rolex GMT-Master II 126719BLRO (White Gold) — Cross-shopped by buyers who want a white gold sports watch with a dual-time-zone function at a lower price point. The GMT-Master II offers a proven in-house movement and broader brand recognition in some circles, though it lacks the Aquanaut's design exclusivity and Patek's manufacture prestige.

The Bizak & Co. verdict
The Patek Philippe Aquanaut 5164G-001 is one of the most coherent executions in the entire Aquanaut range: a practical complication, a precious metal that adds genuine elegance without sacrificing the sporting character, and a dial-strap combination that photographs well and wears even better. Brand new with a full set, it represents the cleanest possible entry into this reference — no service history questions, no originality concerns, no missing documentation. At $172,474 you are paying for scarcity, condition certainty, and the specific combination of white gold and Travel Time that the market prices accordingly.
From the dealer desk, the honest verdict is this: if you have decided the Aquanaut is your watch and the Travel Time complication matches how you actually live, the white gold variant is the version you will not want to trade away in three years. The references that sit on our shelves longest are the ones that compromise somewhere — wrong metal for the buyer's taste, wrong complication for their lifestyle. The 5164G-001 compromises on nothing for the right buyer, and that is exactly why it moves when a clean example arrives.
FAQ: 5164G-001
Why is the Patek Philippe Aquanaut 5164G-001 so expensive?
Three factors drive the price: 18K white gold is a costly material to machine and finish to Patek's standards, the Travel Time complication adds movement complexity and hand-assembly time, and Patek's authorized production volumes are deliberately limited. A brand-new, full-set example at $172,474 reflects all three of those realities plus current secondary-market scarcity for white gold complicated Aquanauts.
How does the 5164G-001 wear on the wrist — is 40.8mm too large?
The 40.8mm case wears closer to a 40mm sports watch than a 42mm tool watch because the integrated rubber strap keeps the overall footprint compact and the case sits low on the wrist. Most buyers with a 7-inch wrist or larger find it proportionally ideal; it is not a small watch, but it is not an oversized one either, and the white gold case gives it enough presence to justify the size.
What movement is inside the Patek Philippe 5164G-001?
The 5164G-001 is powered by an automatic Patek Philippe manufacture caliber with a Travel Time module — it drives the dual local and home time display via the two pushers flanking the case. Patek does not publicly detail every specification for every caliber variant, so we recommend consulting the official Patek Philippe technical documentation or asking your authorized dealer for the precise caliber designation and specifications.
Is the Aquanaut 5164G-001 a good investment?
White gold Aquanaut complications have demonstrated strong demand retention over time, and brand-new full-set examples are among the hardest configurations to source. That said, no watch purchase should be made purely as a financial bet — market conditions shift, and past performance on secondary prices does not guarantee future results. Buy this reference because you want to wear it and it fits your life; the investment case is a secondary benefit, not the primary reason to own it.
