Patek Philippe Aquanaut 5167/1A-001
Known as Aquanaut on the bracelet
The 5167/1A-001 is the steel-bracelet Aquanaut, the version most collectors chase and the one hardest to get. Patek launched the 5167 line in 2007 for the Aquanaut's 10th anniversary on the embossed 'tropical' rubber strap, and the integrated steel bracelet variant, the 5167/1A, joined the following year. It runs a 40mm rounded-octagon steel case, the embossed black dial with applied gold Arabic numerals and gold-toned hands, a date at 3, and the caliber 324 S C automatic underneath a sapphire caseback. This is the sport Patek you can actually wear in the water and still bring to dinner. The rubber-strap 5167A is the classic; the 5167/1A on the matching brushed-and-polished bracelet is the flex. Patek discontinued the reference in 2025, which locked the supply and pushed the whole market up.
Produced: 5167 line introduced 2007; 5167/1A steel-bracelet variant from 2008 to discontinuation in 2025

Market & Value
This is a discontinued steel-bracelet Patek sport watch, so the pricing behaves accordingly. Retail on the 5167/1A landed in the low-to-mid $40,000s before it left the catalog, but almost nobody bought one at the counter; the reference sat on multi-year waitlists at authorized dealers, which is exactly why the secondary market runs well above sticker. As of 2026, full sets with box and papers trade broadly in the high-$60,000s into the $90,000s depending on condition, year, and completeness, with clean recent examples on the bracelet commanding the top of that band. The 2025 discontinuation added roughly 15% to strong examples in the months right after the announcement, and the model is up meaningfully over the past five years. Liquidity is real: well-kept pieces move in a few weeks, and roughly 85% of what comes to market carries box and papers. The bracelet 5167/1A consistently clears more than the rubber-strap 5167A because the bracelet was the harder allocation to get and the harder piece to fake into a full set.
What to Know Before You Buy
Confirm the full set. The value gap between a watch-only 5167/1A and a complete box-and-papers example is thousands of dollars, and on a discontinued reference the certificate of origin matters more every year. Check the bracelet condition closely: the polished center links show hairlines and desk-diving marks fast, and a stretched or heavily-worn bracelet drags the number down. Make sure the bracelet is the correct 5167/1A integrated bracelet and not a strap-model case fitted later; the endlinks and clasp are reference-specific. The 324 S C is a proven caliber, but any Patek should show a clean service history or run within spec on a timing machine before you write a check. Finally, the 40mm case wears larger than the number suggests because of the wide lugless profile, so anyone valuing one sight-unseen should still handle it. Gray-market and 'unworn' claims on a discontinued piece deserve extra scrutiny on stickers, plastic, and matching serials.
