Audemars Piguet Royal Oak 14790ST Review

THE FIRST LOOK

Audemars Piguet Royal Oak 14790ST First Impressions

What hits you the moment you pick up the 36mm Royal Oak.

The Audemars Piguet Royal Oak 14790ST is smaller in the photograph than it is in the hand, which is the opposite of what almost every other watch does. Pick it up and the first thing you register is not the diameter, it is the density. Across the Audemars Piguet watches we handle, this one surprises people most consistently, because the octagonal bezel and the way the bracelet grows straight out of the case make the whole thing read as one solid object rather than a watch head with a strap attached to it.

Then you notice the gold. The eight bezel screws are yellow gold against steel, a detail Audemars Piguet quietly dropped on later references, and in person they give the bezel a warmth that photographs flatten completely. The dial does something similar. Depending on the example, the tapisserie sits either crisp and geometric or soft and almost woven, and it shifts as you tilt it. This is a watch from the 1990s that does not feel like a period piece. It feels like the design brief has not aged at all.

THE WEARING EXPERIENCE

How the Audemars Piguet Royal Oak 14790ST Wears

Real wrist presence, real numbers, and who the 36mm case actually suits.

The Audemars Piguet Royal Oak 14790ST measures 36mm across the bezel but roughly 39.5mm including the crown, with a lug to lug near 46.5mm. Those numbers undersell it. Because the bracelet leaves the case at a wide angle rather than tucking under, the watch occupies wrist real estate the way a 38mm would. On a 6.5 inch wrist it is close to ideal. On a 7 inch wrist it reads as a deliberately sized watch rather than a small one. Past about 7.5 inches it does start to look modest, and that is the honest cutoff. Sizing preference has shifted hard in the last few years, and if you want the broader context on where the market has landed, our breakdown of the most popular Rolex sizes tracks the same trend across the wider category.

Thickness is where this reference quietly wins. At 8mm it disappears under a cuff entirely, and after a full day you stop noticing it. At around 94 grams it is light enough to sit still without being so light it feels hollow, and because the mass is spread across the bracelet rather than concentrated in the case, it stays centered instead of rolling. The bracelet also tapers aggressively, which keeps the back of the wrist comfortable in a way modern integrated designs with flatter tapers do not always manage. This is a watch you can wear seven days straight without thinking about it.

BUILD QUALITY

Audemars Piguet Royal Oak 14790ST Specifications

Case, dial, bezel, and bracelet, evaluated by hand rather than off a spec sheet.

Case

The Audemars Piguet Royal Oak 14790ST case is a scaled interpretation of the original 5402 architecture, and the construction detail that matters is that the caseback is not a separate screw-down component. It is part of the midcase, secured with gold screws, and the movement is fitted from the dial side. That is an expensive way to build a watch and it is the reason the case profile stays at 8mm. Handle a clean example and the bevels running along the case flanks are sharp, the transition from brushed top surface to polished chamfer is crisp with no rounding, and the whole thing feels machined rather than stamped.

The crown screws down with a short, positive action, though it is small by modern standards and hand winding takes patience. Water resistance is 50m, meaning rain and hand washing rather than swimming, especially on a case opened for service several times over thirty years. The thing to assess above all else is polishing, because the Royal Oak case lives or dies on bevel sharpness and an over-polished 14790 never recovers its geometry. Look at the flanks from an angle, in raking light.

Dial and Bezel

The octagonal bezel is the signature, and on the 14790ST it is fixed, brushed on top, polished on the flanks, and held by eight hexagonal screws in yellow gold. Those gold screws are a period detail worth understanding, because they thread through to gold nuts on the underside and give the bezel a two-tone accent that later steel-screw references do not have. Check that all eight are present, aligned, and unmarred. A chewed screw head is a sign of an unqualified watchmaker having been inside the case.

Dials are where this reference gets genuinely interesting. The 14790 was produced with petite tapisserie and grande tapisserie patterns across black, silver, slate grey, white, blue, and the deep Yves Klein blue that has become the collector favorite. Applied indices are steel, sharply faceted, and catch light independently of the dial texture. The date sits at 3 o'clock, and depending on series it appears either framed or in the flush "no box" execution. Lume is minimal and largely decorative at this point on most examples, so treat this as a daylight watch.

Bracelet

The integrated bracelet is where the labor went. Links taper sharply toward the clasp, each finished with brushed tops and polished bevels, and the articulation is fluid enough that the bracelet drapes rather than hinges. The clasp is a folding AP design carrying the maker's mark, with eight screws in the bracelet including the clasp screws.

Two realities to accept. First, stretch: a thirty year old bracelet with worn link pins develops play, which on a Royal Oak shows as droop between the case and the clasp, correctable but not cheap. Second, there is no strap escape route. You wear it on the bracelet or you do not wear it, so bracelet condition is not a secondary concern on this reference. It is the concern.

EXPERT TIP | Robertino Altieri | WatchGuys CEO

What to Check on a Pre-Owned 14790ST

"Three things, in order. One, hold the bracelet up by the clasp and look for droop, because a stretched bracelet is a four figure fix and most sellers will not mention it. Two, look at the case bevels in angled light, since an over-polished Royal Oak never comes back. Three, count and inspect the gold bezel screws. I have passed on clean-looking examples over two chewed screws, because it tells me who has been inside the watch."

KNOW WHAT YOU ARE BUYING

Audemars Piguet Royal Oak 14790ST Dial Series Explained

Fourteen years of production, three collector-recognized series, and a price spread most buyers never see coming.

The Audemars Piguet Royal Oak 14790ST ran from 1992 to 2006, and collectors divide that run into three series by index length, handset, and dial furniture. This matters more than condition grading here, because the gap between a common third series example and a sought-after early or rare dial example is wider than the gap between a good and an average example within the same series. Shop by price alone and you will cross-shop watches that are not actually the same watch.

Layered on top of the series structure are the dial codes carried in the full reference, for example 14790ST.OO.0789ST followed by the dial suffix. The .05 designates the Yves Klein blue, which reads bright in direct light and turns almost purple in shadow. The .01 covers a muted blue or grey petite tapisserie that is scarcer than the Yves Klein despite drawing less attention. There are also black military dials with luminescent Arabic numerals, slate grey grande tapisserie examples, and a small number of steel and tantalum builds. Separately, some black dials have gone tropical, fading toward brown, and those command the strongest premiums of all when the fade is even and documented. The lineage runs straight back to the 39mm original, and if you want the full-size expression of the same design language the Audemars Piguet Royal Oak 15202 is the modern descendant of that first Jumbo.

UNDER THE HOOD

Audemars Piguet Royal Oak 14790ST Movement Review

How the movement performs where it matters: on the wrist, every day.

The Audemars Piguet Royal Oak 14790ST runs the calibre 2225 across the bulk of its production, an automatic with 36 jewels beating at 28,800 vph, adjusted to five positions, driving a 21k gold bidirectional rotor and delivering roughly 40 hours of reserve. It measures just over 3mm thick, which is the entire reason the case sits at 8mm. Collectors also report the earliest examples fitted with the calibre 2125 and later production moving to the calibre 2325, all sharing Jaeger LeCoultre derived architecture from the period when Audemars Piguet held a significant stake in JLC. If provenance matters to you, an archive extract is the only way to settle which caliber a given example left the factory with.

In daily use it behaves like a well-sorted vintage automatic rather than a modern chronometer. A freshly serviced example should hold a few seconds a day. Anything drifting beyond ten seconds a day is telling you it is due. The 40 hour reserve is the practical weakness: take it off Friday evening and it is dead by Sunday morning, so this is a watch that wants to be worn or wound. The rotor is audible if you listen for it, a soft whir rather than the rattle of a cheaper caliber, and the date advances cleanly around midnight without the snap of a modern instantaneous mechanism. The caseback is solid, so none of this finishing is visible, which is a genuine shame given the gold rotor sitting behind it.

EXPERT TIP | Robertino Altieri | WatchGuys CEO

Budget for Service Before You Buy

"On a discontinued reference like this one, a full overhaul at the brand is a four figure job and the turnaround runs long, because the caliber is out of current production. Buy an example with recent service paperwork and you have effectively saved yourself several thousand dollars and a year of waiting. I would rather pay a premium for a serviced 14790 than get a bargain on one with no history at all."

MARKET VALUE

Audemars Piguet Royal Oak 14790ST Price

What the 14790ST actually costs right now, and what moves the number.

The Audemars Piguet Royal Oak 14790ST carries a market value in the low thirty thousands as of mid 2026, with standard dial complete sets clustering between roughly $30,000 and $38,000. Move to the dials collectors chase, tropical black, Yves Klein blue, documented first series, and asking prices run from the low forties into the low fifties. That spread of more than $20,000 across the same reference number is the single most important pricing fact on this page, and it is why buying a 14790 without understanding series and dial codes is a genuine risk.

The trend has been strong. The reference appreciated roughly 13.6 percent over the trailing twelve months against an Audemars Piguet brand index up around 6.3 percent and an overall market up around 9.2 percent, and it carries a low risk score with a median of 19 days to sell, meaning liquidity is real rather than theoretical. The driver is straightforward: buyers who want an authentic Royal Oak with gold bezel screws and hand-finished bracelet work have been priced out of the Jumbo, and this is where they land.

HEAD TO HEAD

Audemars Piguet Royal Oak 14790ST Comparison

The 14790ST against the three watches buyers actually cross-shop it with.

Audemars Piguet 14790ST vs. Audemars Piguet Royal Oak 15300ST (The Successor)

This is the real decision. The Audemars Piguet Royal Oak 15300 replaced the 14790 in 2005 with a 39mm case, the calibre 3120, a 60 hour reserve, and a display caseback that finally shows the movement. It is the better watch on paper and it costs about four thousand dollars more. What you give up is the 8mm case, since the 15300 sits over 9mm, and the gold bezel screws, which the 15300 does not have. Choose the 15300 if you want a modern ownership experience and a larger case. Choose the 14790ST if you want the thinner, more period-correct Royal Oak and you value those gold screws.

Audemars Piguet 14790ST vs. Audemars Piguet Royal Oak 15450ST (The Modern Midsize)

If your objection to the 14790 is that 36mm is too small but 39mm is too large, the Audemars Piguet Royal Oak 15450 splits the difference at 37mm with the calibre 3120 and a display back. It costs roughly six thousand dollars more and it is unambiguously the more practical daily watch. What it is not is distinctive. The 15450 is a modern production Royal Oak that thousands of people own in the same configuration, whereas a first series or rare dial 14790 is a watch other collectors stop and ask about. You are choosing between convenience and character.

Audemars Piguet 14790ST vs. Patek Philippe Nautilus 3800/1A (The Period Cross-Shop)

The Patek Philippe Nautilus 3800 is the other Genta-derived midsize integrated steel sports watch of the same era, and it is the piece 14790 shoppers most often look at second. It is also roughly double the money at around $64,000. The Nautilus wears softer and rounder, the 14790 wears sharper and more architectural, and both are excellent. The honest read is that the Patek premium here is a brand and scarcity premium rather than a build quality premium. If you want the era's midsize integrated design and the budget is the constraint, the Audemars Piguet gets you there for half.

Robertino's Take

"Every one of these comparisons ends the same way for me. The 14790ST is the cheapest ticket into a real Royal Oak, gold bezel screws and all, and it is the only one on this list where you are buying the watch instead of buying the reference number. If someone tells you 36mm is too small, put it on their wrist and watch them stop talking."

THE BOTTOM LINE

Is the Audemars Piguet Royal Oak 14790ST Worth It?

A straight answer on the 36mm Royal Oak.

Yes. The Audemars Piguet Royal Oak 14790ST is the best value in the entire Royal Oak lineup and it is not particularly close. You get the full Genta design language, an 8mm case, yellow gold bezel screws that later references dropped, and hand-finished bracelet work, for roughly a third of what a steel Jumbo commands. It is perfect for the buyer who wants an authentic Royal Oak rather than a status object, for anyone with a wrist between 6 and 7.25 inches, and for collectors who would rather own something with a story than something with a waitlist.

Consider something else if your wrist runs over 7.5 inches, or if a 40 hour reserve and a solid caseback bother you. In those cases the 39mm Royal Oak 15300 or the 37mm 15450 are the better buys and we would tell you so directly. The strongest single reason to choose the 14790ST is that it is the last Royal Oak where the value proposition still favors the buyer, and the trailing twelve month appreciation suggests the market is working that out. To handle examples side by side before deciding, schedule an appointment.

Robertino's Take

"I have watched this reference go from a watch nobody wanted to a watch we sell in under three weeks. Buy the best condition example you can find, unpolished case, tight bracelet, service paperwork in hand, and pay up for it. The cheap ones are cheap for a reason and the difference will cost you more than the discount saved you."
