Name: Audemars Piguet Royal Oak (second-gen "the small Royal Oak") 14790
Brand: Audemars Piguet
SKU: 14790

The 14790 is the second-generation Royal Oak, produced 1992 through 2003, at a 36mm case size that the modern market briefly forgot about and then dramatically remembered. It's the 'small Royal Oak' that runs around half the cost of a 15202 'Jumbo' but has more original Genta-designed character than any post-2000 Royal Oak.

What it is

The original Royal Oak (5402, 1972) was a 39mm case; the 'medium' Royal Oak followed at 36mm. The 14790 launched in 1992 with the caliber 2125 (a JLC-derived automatic with a date complication), replacing the earlier 4100. Production ran through 2003 when the 15300 took over.

Variants exist in steel, two-tone, full-gold, and a Tantalum 'Royal Oak 25th anniversary' commemorative.

Buying notes

Common things to check: dial originality (the petite tapisserie pattern is hand-applied and not field-replicable, service-replacement dials are visible under magnification); bracelet (the integrated bracelet means a wrong-size or wrong-generation bracelet is a value disaster, verify the end-link generation matches the case era); case finishing (the polished/brushed alternation on the Royal Oak case profile is hand-applied; over-restored examples lose the finish definition that makes the watch); papers (AP service papers are the gold standard for provenance; a 14790 without papers should be priced 15-25% below a papered equivalent).

Market read

The 14790 was undervalued from 2008 through 2018, when 36mm cases were considered “too small.” That has reversed. Honest steel-bracelet examples now trade in the high-$10,000s to mid-$20,000s; the market for medium Royal Oaks is much shallower than the 15202 market but the dollar gap to a comparable 15202 has narrowed substantially.

Service expectations

AP-direct service for the caliber 2125 is supported and routine; cost is comparable to other Royal Oak service. Service interval 5-7 years; the integrated bracelet is also serviced (link tightening, case-bracelet alignment) during the appointment. An AP-stamped service card on a 14790 is a meaningful value lift.

Mid-size Royal Oak from the 1980s-1990s trades at a significant discount to the current 15202 yet shares the core Genta design language.

The second-generation 33mm Royal Oak 14790 trades at a modest discount to the 15202 Jumbo because of its smaller case; steel examples represent the entry point and yellow gold commands the most significant premium.

Editorial estimate, 2026 Q2. Actual prices vary by condition, date, and box/papers status.

Movement tier: unclassified · caliber AP Cal. 2125: in-house automatic, 21,600bph, 40h PR, 33j; 21k gold full rotor (not a micro-rotor); direct derivative of Cal. 2124, a separate AP family from the JLC-derived Cal. 2120/2121; produced 1987-1997 · 40h power reserve · family design Gérald Genta

Small case: suits slender wrists (under 6.5 in / 16.5 cm)

36 mm case. A compact, elegant wear. Particularly at home on narrower wrists where larger cases can overhang.

Authentication guide

Last reviewed June 2026

The 14790 is the transitional Royal Oak produced before the current 15300/15400 generation. It uses the Cal. 2225 movement and shares the core Tapisserie dial architecture. Authentication focuses on dial texture authenticity, eight-screw bezel uniformity, and movement caliber confirmation.

Dial (Grande Tapisserie texture)

Original: The Tapisserie pattern consists of raised squares machined during dial production. The pattern is genuinely three-dimensional and each square edge is crisply defined when viewed under magnification.

Replacement tells

Tapisserie that appears flat or printed under directional lighting -- genuine Tapisserie casts a shadow at each square edge
Pattern that becomes less defined toward the dial edge or near the applied hour markers
Dial surface that lacks the characteristic tactile quality of the machined Tapisserie

Eight-screw bezel

Original: Eight Torx-head screws of equal apparent depth around the bezel. The screw heads should be clean, undamaged, and uniformly seated. On a 14790, all eight screws are visible and their heads should not show tool marks inconsistent with factory assembly.

Replacement tells

Screw heads at inconsistent depths -- one or more screws that appear lower or higher than the others
Tool marks on screw heads inconsistent with factory Torx assembly (indicating third-party caseback or bezel work)
Bezel-to-case gap visible at any position around the circumference

Integrated bracelet

Original: AP integrated bracelet with brushed center links running lengthwise and polished outer links. The bracelet tapers toward the AP deployment clasp. For the 14790 generation, the bracelet dimensions are narrower than the current 15500.

Replacement tells

Later-generation AP bracelet with different link dimensions fitted to the 14790 case
Brushing direction on center links running across rather than along the link (incorrect direction)
AP clasp with typography or deployment mechanism inconsistent with 1990s-era AP production

Cal. 2225 is the movement specific to the 14790 generation (earlier 14790 may carry Cal. 2225 or its predecessor 2120/2800). The movement is an ultra-thin automatic.
No quickset date: the 14790 date corrects only by rotating the crown through the hours. If a quickset date function is present at 2:15, the movement has been replaced.
AP exhibition caseback is standard on the 14790. Any solid caseback on a stated 14790 is incorrect and suggests a case swap.
The rotor should oscillate smoothly with no lateral play. The bidirectional rotor is characteristic of the 2225 family.
