Patek Philippe introduced the Ref. 5164A at Baselworld 2011 — the first Aquanaut ever to feature a travel time complication, some 14 years after the line's debut in 1997. The 40.8 mm stainless steel case houses Caliber 324 S C FUS with a skeletonized home-time hour hand; two side pushers set the second time zone without interfering with the running-seconds mechanism. In the trade the reference goes by collector shorthand such as "Aquanaut TT" or "Aquanaut Travel Time Steel." With 120 metres of water resistance and a black embossed dial fitted with white-gold applied indices, the 5164A was the sportiest dual-time in the Patek catalogue from day one.
## Discontinued on 1 February 2024 — and What That Means for the Price
On 1 February 2024 Patek Philippe removed the steel version from its regular offering. The current catalogue retains the 5164R-001 in rose gold (introduced in 2016) and the 5164G-001 in white gold; only precious metal remains available new. Anyone who has followed how steel Pateks behave after discontinuation knows the dynamic well: the natural price ceiling imposed by fresh dealer stock disappears the moment no new steel example can be ordered from an authorised retailer. The black dial — often listed in collector circles as "Black Tropical" — is the standard configuration on the secondary market, while the rarer Tiffany-dial variant of the 5164A-001 commands its own distinct price tier.

Brand profile: Patek Philippe
Patek Philippe produces the world's most exclusive watches. Counterfeits are typically identifiable by their build quality — the genuine article sets standards that are nearly impossible to replicate.
- Dial embossing Nautilus: the genuine piece has 11 RAISED horizontal stripes with precise edges. 3D depth is visible under raking light. Flat stripes = fake.
- Case thickness Nautilus 5711: EXACTLY 8.3mm measured with calipers. Deviation of +0.5mm = fake with 7750 base or Miyota.
- Weight Nautilus 5711/1A: 131.4g ± 1g (with bracelet). >5g deviation = suspect.
- PP Seal on rotor (display back): the genuine Patek Philippe Seal features DEEP 3D engraving with sharp edges. Fake rotors have a shallow stamp.

What matters at this price point
At $104,946 we are no longer talking about an everyday watch but a collector's piece. Every detail drives the price: an original dial can be worth five figures more than a service dial, missing papers noticeably depress the value, and an over-polished bezel is effectively lost money. Anyone buying in this range should take their time and, when in doubt, take a second look.
Watch out for swings: This reference has an above-average volatility of 31.6 percent. In concrete terms: the price can move by several hundred euros within a few weeks. Check the current value before buying or selling — old listings or auction results from two months ago are of little help.
What to look out for when buying?
- Authenticity: The serial number and reference on the case must match the papers. A professional authenticity check of the Patek Philippe Aquanaut reliably rules out counterfeits.
- Condition: Check scratches on the case and bezel — professional refurbishment can leave traces.
- Service history: A documented service by the manufacturer or a certified watchmaker increases the value.
- Scope of delivery: Box, papers and warranty card make a noticeable price difference on the Aquanaut.
- Independent certification: The CPS-52 standard covers 52 checkpoints — from the serial number and the timing machine to water resistance. The result is secured on the blockchain and can be verified at any time.
