Audemars Piguet Royal Oak 14790SA Review

THE FIRST LOOK

Audemars Piguet Royal Oak 14790SA First Impressions

What hits you the moment you pick up the 14790SA.

The Audemars Piguet Royal Oak 14790SA reads as a gold watch first and a steel watch second, which is the reverse of what the spec sheet implies. Pick one up and the yellow gold bezel, the gold center links, and the gold hands and applied markers claim your attention before you register that the case flanks and outer links are steel. Among 1990s Audemars Piguet watches this is the reference that photographs badly and presents beautifully in person, because a camera flattens the two metals into one muddy tone while your eye separates them instantly. The Audemars Piguet Royal Oak 14790SA carries the same brutal case geometry as the steel version, but the warmth of the gold softens it into something closer to a dress watch.

The second impression is variance. Two examples from the same production year can look a decade apart, and after handling enough of them you stop assessing the watch and start assessing its history. One arrives with a bezel whose brushed top is still flat and whose eight screw countersinks still have sharp shoulders. The next has been buffed into a soft, shiny pillow, and the difference is worth thousands of dollars.

THE WEARING EXPERIENCE

How the Audemars Piguet Royal Oak 14790SA Wears

How the 14790SA actually wears, day in and day out.

The Audemars Piguet Royal Oak 14790SA wears larger than 36mm has any right to. The integrated bracelet eliminates conventional lugs, so instead of a small case sitting between two strap ends, you get one continuous 46.5mm span of metal from bracelet to bracelet. Nothing visually interrupts it, which is why the 14790SA covers more wrist than a 38mm watch on a leather strap. It suits roughly 6.25 to 7.5 inch wrists comfortably. Below that the bracelet taper runs out of adjustment, and above 7.5 inches the case starts to look deliberately vintage rather than correctly proportioned.

Weight is where the two-tone separates itself from the steel version. The gold bezel sits at the top of the case and the gold center links run the full length of the bracelet, which puts real mass in the two places you feel it. The watch does not feel heavy in a burdensome way, it feels dense, and the bracelet settles into the wrist rather than sliding around it. At 8.1mm the case disappears under a cuff completely. There is no negotiation with a shirt, no catching, no rolling the wrist to check the time. This is one of the few Royal Oaks you can genuinely forget you are wearing.

BUILD QUALITY

Audemars Piguet Royal Oak 14790SA Specifications

Breaking down the 14790SA component by component.

Case

The Audemars Piguet Royal Oak 14790SA uses a 36mm steel case with the construction that has defined the Royal Oak since 1972, where eight hexagonal screws pass through the bezel into nuts on the caseback side rather than into the case itself. From the side the finishing story is obvious: a wide brushed top, a mirror-polished bevel running the full perimeter, then brushed flanks. The transition is a hard line with no blending, and on an unpolished example a fingernail finds it instantly. The crown screws down and the caseback is solid steel, giving 50m of water resistance. Treat any unserviced example as water resistant to nothing.

Bezel

The 18k yellow gold octagonal bezel is why the 14790SA exists and where most of its value sits. It is solid gold rather than plated, so it cannot wear through to a base metal. What it does instead is soften, because 18k gold is meaningfully less scratch resistant than the steel around it. On an original bezel the brushed top face is dead flat, the polished bevels between the eight facets are crisp, and the countersinks around each screw have defined shoulders. Refinished, those shoulders round off and the flat face develops a subtle dome. The screws are white gold on most examples, giving a three-metal contrast that looks far better in person than in photographs.

Dial

Dial execution on the Audemars Piguet Royal Oak 14790SA changed across a fourteen year run, with grey, champagne, silver, white, and blue all appearing in two-tone. Early examples carry the petite tapisserie pattern, a fine waffle grid that catches light in narrow bands and looks almost textile-like at an angle. Later examples use a bolder tapisserie with shorter applied indices. Everything that is not the tapisserie is gold-toned to match the bezel: the applied batons, the hands, the printed detailing. Early dials use tritium, usually aged to a warm cream that suits the gold, while later production moved to Super-LumiNova. Lume is decorative on any example. The unmagnified date sits flush at three o'clock.

Bracelet

The integrated bracelet on the 14790SA is the component buyers most often underestimate. It tapers hard from case to clasp, and each link carries the same brushed top and polished bevel as the case, with the gold center links finished to a higher shine than the steel around them. Early bracelets came from Gay Freres with single-pin construction and a plain folding clasp, while later production moved to dual screws and an AP-signed clasp. Articulation is excellent when the bracelet is tight and poor when it is not. Because each link is a mixed-metal sandwich, correcting stretch costs more here than on the steel version, and replacement gold center links are scarce.

EXPERT TIP | Robertino Altieri | WatchGuys CEO

The Bracelet Test Most 14790SA Buyers Skip

"Hold the watch by the clasp and let it hang. Then run a finger down the bracelet and watch how much the links separate. On a tight 14790SA bracelet you see almost nothing. On a stretched one you see daylight between every link. I have seen buyers negotiate hard on a scuffed bezel and completely ignore a bracelet that is going to cost them real money to sort out. On the two-tone the gold center links are the expensive part, and finding correct period replacements is a slow, frustrating hunt."

CONDITION MATTERS

Audemars Piguet Royal Oak 14790SA Gold Wear and Condition

Why the state of the gold decides what a 14790SA is worth.

On the Audemars Piguet Royal Oak 14790SA, condition is not a footnote to price, it is most of the price. Steel forgives thirty years of wear because a competent refinish returns it to something close to factory geometry, and the material lost is negligible. Gold does not work that way. Every pass of a polishing wheel across an 18k bezel permanently removes metal that cannot be put back, and because the Royal Oak bezel is defined entirely by hard edges and precise screw countersinks, the damage shows immediately. A twice-refinished bezel loses the flat top face, gains a soft dome, and the eight screw seats widen into shallow craters. Collectors spot it in a single photograph, which is exactly why the price spread on this reference is so wide.

The checks are simple once you know them. Hold a reflected straight line across the bezel top face and see whether it stays straight or bends. Check that the polished bevels between facets are even in width all the way around, because uneven bevels mean a wheel touched them. Look where the gold center links meet the steel outer links, since refinishing blurs the crisp step between the two metals. Then check the caseback: deep, sharp engraving means it is untouched. Finally, ask for service history, because a manufacture service often includes a refinish by default. If you want a second opinion first, schedule an appointment and put one on your wrist in person.

UNDER THE HOOD

Audemars Piguet Royal Oak 14790SA Movement Review

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

The Audemars Piguet Royal Oak 14790SA runs the Calibre 2225, an automatic built on Jaeger-LeCoultre's 889/2 architecture with a 21k gold rotor, beating at 28,800 vibrations per hour with a 40 hour reserve. The earliest examples used the Calibre 2125 and the last used the Calibre 2325, but all three share a base and behave identically on the wrist. A healthy, recently serviced example holds a few seconds a day, respectable for its generation and behind anything modern. The 40 hour reserve is the real limitation: take it off Friday evening and it has stopped by Sunday morning.

Winding feel is the best part of the experience. The crown unscrews smoothly and hand-winding is quiet and tight with no grit, which is a useful first diagnostic on a used example. The rotor winds bidirectionally and is close to silent. The date is not quick-set, so you advance it by running the hands past midnight repeatedly, tedious after a long period off the wrist. On servicing, budget realistically. Audemars Piguet will service a vintage Royal Oak, but turnaround on discontinued calibers runs long and the manufacture typically refinishes the case as part of the job. A qualified independent familiar with the JLC 889 family is usually faster, cheaper, and will leave the case alone if you ask.

EXPERT TIP | Robertino Altieri | WatchGuys CEO

Tell Your Watchmaker Not to Touch the Case

"This is the single most valuable sentence I can give a 14790SA owner. When you send it for service, put in writing that you do not want the case or bracelet refinished. Most service departments treat cosmetic refinishing as a courtesy and do it by default. On a two-tone Royal Oak that courtesy can take thousands of dollars off the watch, because you cannot un-polish a gold bezel. Ask first, always."

MARKET VALUE

Audemars Piguet Royal Oak 14790SA Price

What the 14790SA costs right now on the secondary market.

The Audemars Piguet Royal Oak 14790SA sits at the bottom of the authentic Audemars Piguet market, which is exactly what makes it interesting. An honest example with wear and no story trades in the high teens. A crisp, unpolished, full set example pushes into the mid twenties. That is roughly half what a modern steel Royal Oak commands for finishing that is not meaningfully different. Two-tone remains less fashionable than steel, and that unpopularity is the discount you are handed. Compare it against later two-tone Audemars Piguet watches and the gap is obvious.

Twelve month trend data shows the 14790SA essentially flat, tracking the broader Audemars Piguet market within roughly a percentage point. That is not exciting, but for a thirty year old discontinued reference it signals that price is being set by real demand rather than speculation. The variables that move a specific example are condition of the gold, completeness, and dial. Box, papers, and an AP archive extract matter more here than on most references, because the extract confirms original configuration and settles any question about a swapped dial.

HEAD TO HEAD

Audemars Piguet Royal Oak 14790SA Comparison

The 14790SA against the alternatives buyers actually cross-shop.

Audemars Piguet Royal Oak 14790SA vs. Audemars Piguet Royal Oak 14790ST (Steel)

This is the decision almost every buyer faces, and it comes down to taste and budget rather than quality. Identical case, identical caliber, identical dimensions. The steel version is the collector default and trades several thousand dollars higher for that reason alone, an unusual situation where the version containing precious metal is the cheaper one. The 14790SA gives up liquidity and gains warmth, weight, and a lower entry price, while carrying higher condition risk because gold cannot be refinished without consequence. Choose steel if resale speed matters. Choose two-tone if you want the most watch per dollar and intend to keep it.

Robertino's Take

"I have sold both versions of the 14790 for years and the two-tone is the better buy right now, full stop. You are getting solid 18k gold on the bezel and through the bracelet for less money than the all steel version. That only makes sense because of fashion, and fashion moves. The one thing I will not compromise on is the bezel. I would rather sell a client a two-tone with a mint bezel and a scuffed case than the reverse."

Audemars Piguet Royal Oak 14790SA vs. Audemars Piguet Royal Oak 56023SA (Quartz Predecessor)

The Audemars Piguet Royal Oak 56023 is the 1980s two-tone that most closely resembles the 14790SA from three feet away, usually for a few thousand dollars less. The difference is inside. The 56023SA runs the quartz Calibre 2506, making it thinner at around 7mm, lighter, and effectively maintenance-free apart from batteries. The quartz Royal Oaks are properly finished watches rather than compromises, and some buyers genuinely prefer them. But quartz caps long-term collector interest. If your budget reaches the 14790SA, the automatic is worth the difference.

Audemars Piguet Royal Oak 14790SA vs. Audemars Piguet Royal Oak 25594SA (Day-Date Moonphase)

If you want the same 36mm two-tone case with more going on, the Audemars Piguet Royal Oak 25594 adds a pointer day-date and a moonphase, and its unusual dial layout has earned a cult following. It costs thickness, roughly 9mm against 8.1mm, and simplicity, since a complicated vintage caliber means costlier service and more to go wrong. Total production ran to roughly 1,800 pieces, so it is genuinely scarcer. Choose the 14790SA for a clean daily watch, the 25594SA for a conversation piece.

THE BOTTOM LINE

Is the Audemars Piguet Royal Oak 14790SA Worth It?

Is the 14790SA worth your money?

Yes. The Audemars Piguet Royal Oak 14790SA is the least expensive honest way to own a properly finished Audemars Piguet, and nothing else near this price gets close. The case and bracelet came out of the same workshops and standards that produce Royal Oaks costing three times as much, the 36mm proportions have aged into exactly the size the market now wants, and the two-tone is discounted for reasons of fashion rather than quality.

It suits the buyer who wants a grail-brand watch, has around twenty thousand dollars, and cares more about what is on their wrist than what the market thinks of it. It is a poor fit for anyone needing a long power reserve, real water resistance, or a watch they can forget for weeks. It is also wrong for a flipper, since two-tone moves slower than steel and condition makes pricing harder to predict. The strongest reason to buy is simple: authentic Audemars Piguet case finishing, in solid gold and steel, for roughly half the price of the modern equivalent. If two-tone is not for you, the Audemars Piguet Royal Oak 15400 covers the other end of the same lineage.

Robertino's Take

"The 14790SA is the watch I recommend when someone tells me they want an AP but the steel prices do not work. It is a real Royal Oak, hand-finished the same way, at a price that still surprises people. Buy the condition, not the deal. A clean bezel and a tight bracelet are worth paying up for, and a cheap one with a soft bezel is not a bargain, it is somebody else's problem."
