Patek Philippe is renowned for its ability to create watches that remain timeless while subtly evolving with each generation. In 2025, the brand made a notable update to its Aquanaut collection by discontinuing one of its most beloved references: the Aquanaut 5167/1A-001. This decision has sparked renewed interest in the model, raising questions about what exactly has changed, what remains, and why this reference continues to capture attention on the secondary market, where its limited availability and scarcity have begun to drive significant demand.
This overview explores the significance of the now-discontinued Aquanaut 5167/1A-001, its defining features, the continuation of its sibling reference, and how these updates shape the future of the Aquanaut line.
First introduced in 1997, the Patek Philippe Aquanaut brought a more contemporary and sport-forward aesthetic to the brand, complementing the Nautilus while maintaining its own distinct identity. In 2007, the Aquanaut received a major evolution with the introduction of the 5167A series, replacing the earlier 5065A model. This update included a larger 40mm case, slimmer profile, and subtle refinements to the embossed dial pattern, resulting in a watch that felt both more modern and wearable for a wide range of wrist sizes.
Within this series, two primary configurations existed: the 5167A-001 with a rubber strap, and the 5167/1A-001 featuring an integrated stainless steel bracelet. Both models featured a 40mm stainless steel case with a slim profile of approximately 8.1mm, housing the calibre 324 S C automatic movement with a date complication and sweep seconds. The embossed black dial, paired with applied white gold numerals and luminous markers, created a refined yet distinctly sporty look.
In 2025, Patek Philippe officially discontinued the Aquanaut 5167/1A-001, the bracelet variant of the classic Aquanaut. While the watch on its composite rubber strap (reference 5167A-001) remains available in the collection, the option to acquire this model on a stainless steel bracelet directly from Patek Philippe is no longer possible.
This move comes after the brand’s decision to discontinue the stainless steel Aquanaut Travel Time 5164A in 2024. Together, these changes mark a broader strategic shift in the Aquanaut line, reinforcing its identity as a sport-luxury watch distinguished by its rubber strap, while stainless steel bracelets become more associated with the Patek Philippe Nautilus collection.
Unsurprisingly, the discontinuation of the 5167/1A-001 has heightened its desirability on the secondary market, where collectors are increasingly drawn to models with proven scarcity and limited availability.
While both the 5167/1A-001 and the 5167A-001 share the same case dimensions, movement, and dial design, their wear experiences differ noticeably. The stainless steel bracelet model offered a seamless, integrated aesthetic that elevated the watch’s versatility, allowing it to transition effortlessly from casual to formal settings. Its brushed and polished links echoed the finishing standards found on the Nautilus bracelet, adding a layer of refined complexity to the Aquanaut’s sporty design.
In contrast, the rubber strap version emphasizes the Aquanaut’s original spirit as a modern, adventure-ready sports watch. Lightweight and exceptionally comfortable, the tropical strap is resistant to salt water, UV rays, and wear, enhancing the model’s practicality for everyday use or travel.
The absence of a bracelet option moving forward has only amplified the perception of the 5167/1A-001 as a distinctive and increasingly scarce reference among collectors.
Despite discontinuing the bracelet variant, Patek Philippe continues to offer the 5167A-001 on a rubber strap as the entry-level Aquanaut, alongside the rose gold 5167R-001. The decision to streamline the collection reflects the brand’s strategy of maintaining clear distinctions between its major sports watch families: reserving the integrated steel bracelet aesthetic for the Nautilus, while positioning the Aquanaut with its signature strap for a sportier, more contemporary character.
The Aquanaut remains one of Patek Philippe’s most in-demand models, and the decision to discontinue the bracelet version will likely further increase demand for the remaining stainless steel-strap models, as collectors focus on securing the last accessible options in this iconic sports line.
The Aquanaut 5167/1A-001 holds a unique place in the collection’s history as the only stainless steel time-and-date Aquanaut reference offered on a bracelet. Its discontinuation marks the end of an era for enthusiasts who appreciated the combination of the Aquanaut’s casual elegance with the versatility and prestige of Patek Philippe’s steel bracelet construction.
While Patek Philippe has not yet announced a direct replacement for the 5167/1A-001, its departure has only amplified interest among collectors who seek models that represent both a practical daily watch and a discontinued reference with enduring relevance. Its limited availability is expected to continue driving strong demand on the secondary market as buyers compete for a reference that is no longer attainable at retail.
The story of the Aquanaut 5167/1A-001 serves as a reminder of Patek Philippe’s thoughtful approach to evolution within its collections. Even small changes, such as the removal of a bracelet option, can carry significant meaning for collectors who value the nuances of each reference. As the Aquanaut continues to define itself through sport-forward design and contemporary wearability, the discontinued 5167/1A-001 remains a testament to a quietly distinctive era in Patek Philippe’s ongoing journey of refinement and innovation.
Today, its scarcity and discontinued status ensure it occupies a special place in the hearts of collectors—solidifying its reputation as a reference with enduring desirability and growing demand on the secondary market.
