Question 1

How does The 1916 Company authenticate a pre-owned Patek Philippe 5167A?

Accepted Answer

Every 5167A we offer goes through a full in-house authentication process: movement inspection, case and dial verification, serial number cross-referencing, and confirmation of box-and-papers status where applicable. Once authenticated, each watch is backed by The 1916 Company's 2-year warranty, covering mechanical function. If you have questions about a specific example, our team is available to walk you through the documentation on file.

Question 2

What makes the 5167A different from the rest of the Aquanaut line?

Accepted Answer

The 5167A is the stainless steel, rubber-strap configuration of the 5167 family, launched at Baselworld in 2007 alongside an upgrade to the caliber 324 S C. It runs three hands plus a date at 3 o'clock, the same basic layout as the original Aquanaut, which keeps the dial clean and legible. The case is 40mm wide and 8.1mm thin, with a screw-down crown and 120m water resistance built into a three-piece steel case. The sapphire caseback lets you view the 21K gold rotor and Geneva-striped finishing. For collectors who want the core Aquanaut proposition without added complications or precious metal premiums, the 5167A is the reference that delivers it most directly.

Question 3

How has the 5167A performed as a collectible, and what should I look for in a pre-owned example?

Accepted Answer

The 5167A has posted strong price appreciation in recent years, outperforming both the broader Patek index and the overall watch market. When evaluating a pre-owned example, prioritize unpolished cases (brushed surfaces on the case front are easy to over-polish and hard to restore), original tropical composite strap or a documented replacement, and full box and papers. The caliber 324 S C is a robust and well-supported movement; service history matters less than on older references, but any watch approaching 5 to 7 years since its last service is worth noting. At The 1916 Company, we document all of these details before a watch reaches our collection, and every piece carries our 2-year warranty.
