The Patek Philippe Aquanaut 5168 was introduced at BaselWorld 2017. At 42.2mm, its case is larger than that of the 5167. Ref. 5168G-001 has this case done in white gold and paired with a blue dial and matching strap.

This is the biggest Aquanaut Patek has ever made – and one of the most surprising. A white-gold case, a blue dial that darkens toward the edge, and a rubber strap that feels right at home on a six-figure watch. Created for the collection’s 20th birthday, this version breaks a few rules while staying true to the Aquanaut’s laid-back spirit. So how did we get from the original 1997 launch to this outsized celebratory model? Let’s take it from the top.
Origin & History
When Patek Philippe introduced the Aquanaut in 1997, it was positioned as a more relaxed, modern alternative to the Nautilus. It kept the rounded-octagon shape and steel case but added a youthful flair with its patterned dial and tropical rubber strap – something no other Patek had at the time. It was the brand’s sportiest model and quietly gained popularity, especially with the release of the 40 mm reference 5167 that became the line’s benchmark.
To celebrate the Aquanaut’s 20th anniversary in 2017, Patek decided to shake things up. Enter this white-gold edition with a larger 42.2 mm case, blue gradient dial, and matching strap – a combination that gave the Aquanaut a new identity while paying subtle tribute to the “Jumbo” Nautilus from 1976. It marked the first time white gold was used in the Aquanaut line, pushing it beyond its tool-watch image into something a bit more unexpected.
Case & Strap
The case is crafted from solid 18k white gold – more precisely, gray gold, a durable alloy that stays white throughout and doesn’t require rhodium plating. Measuring 42.2 mm in diameter and just 8.25 mm thick, it remains the largest Aquanaut to date, yet it wears surprisingly thin. On the wrist, it feels wide but not bulky – something that’s emphasized by the way the case finishes play with light and shape.
Up top, the rounded octagonal bezel has a vertically brushed surface with polished bevels along the edges, adding contrast and dimension. The case flanks feature a brushed finish, while the lugs are polished for a clean break in texture that highlights the watch’s shape. On the right side, the polished screw-down crown is protected by slim guards and marked with Patek Philippe’s Calatrava cross.
Rated for 120 meters of water resistance, the watch can handle swimming or even snorkeling – but most owners will probably treat it as more of a luxury daily driver than a true dive companion.
What ties the whole look together is the blue rubber strap. It is made from a composite material that’s soft, flexible, and designed to match the dial’s embossed checkerboard pattern. The inner part of the strap features recessed grooves that help with comfort and ventilation, especially in warmer weather. It is also designed to be trimmed for a custom fit, giving it that tailored feel right out of the box. A double folding clasp in white gold, also engraved with the Calatrava cross, keeps it securely fastened without fuss.
With the case and strap setting the tone, it is the dial that pulls you in for a closer look.
Dial Design
The dial is finished in a deep blue tone that fades gradually toward a darker edge – a smoked gradient that adds depth without feeling overdone. It features the Aquanaut’s signature embossed pattern, often described as globe or grenade-like. This textured design has become one of the key things people notice about the watch and adds to its sporty, casual look.
White gold Arabic numerals are applied directly onto the surface and paired with luminous-coated hour markers for strong visibility in low-light conditions. The hour and minute hands are also made of white gold and filled with the same luminous material, while the white-lacquered seconds hand stands out clearly as it sweeps across the dial.
At 3 o’clock, there’s a printed date window that blends in with the dial color, keeping the overall layout clean and easy to read. On top, a flat sapphire crystal protects the dial and keeps everything easy to see from different angles.
Underneath all of that, Patek’s in-house movement keeps everything running smoothly – and it’s just as interesting to look at as the dial.
Movement & Functionality
Powering this model is the updated self-winding Caliber 26-330 S C, a movement developed entirely in-house by Patek Philippe. It runs at a frequency of 28,800 vibrations per hour (4 Hz) and delivers a power reserve between 35 and 45 hours. Slim at just 3.32 mm thick, it helps keep the case profile sleek while still packing in 212 parts and 30 jewels.
Compared to its predecessor, this newer caliber brings a few important upgrades. It now features a hacking seconds function – so when you pull the crown, the seconds hand stops, making it easier to sync the time precisely. The movement also benefits from improved winding efficiency and optimized gear tooth profiles for smoother transmission.
The movement uses a free-sprung Gyromax balance, paired with a Spiromax silicon balance spring. These two components enhance long-term accuracy, boost shock resistance, and help protect against magnetism – something that’s increasingly relevant in everyday life.
Flip the watch over, and the sapphire crystal caseback offers a clear view of the movement. The 21k gold central rotor glides on ceramic bearings, and the finishing lives up to the Patek Philippe Seal’s standards. You’ll spot Geneva stripes on the bridges and rotor, circular graining on the baseplate, beveled edges, and black-polished screw heads – details that often go unnoticed but reflect the care behind every component.
For all its precision and complexity, what matters most is how this movement feels in daily use – so let’s take a look at what it’s like on the wrist.
On-Wrist Feel
Even with its larger size, this Aquanaut wears flatter and more comfortably than expected. The 42.2 mm case covers more wrist area than the 40 mm version, but the slim 8.25 mm thickness and curved lugs help it sit low and stay in place. On wrists around 16 cm and up, the watch doesn’t shift or feel oversized – it holds steady without digging in or sliding around.
The rubber strap softens after a few wears and gradually molds to your wrist. Once it breaks in, the watch becomes easier to wear for long stretches, even though the case is made of gold. It still fits under most shirt cuffs and feels secure rather than bulky.
Compared to the steel version, the white gold does make the watch slightly heavier. But instead of feeling too weighty, it gives the watch a sturdier, more solid feel on the wrist – just enough to remind you it is there without getting in the way.
After spending time with it, the appeal becomes clear. So what’s the final verdict?
