Audemars Piguet Royal Oak for Women: 33 mm, 34 mm and 37 mm Compared

The Audemars Piguet Royal Oak that most women choose is the 34 mm Selfwinding for a small to medium wrist, the 37 mm Selfwinding for a medium to larger wrist, or the 33 mm quartz for the smallest wrists. Audemars Piguet does not sell these as a separate women's line, so the choice comes down to diameter, movement and finish. This guide compares the three sizes, explains quartz versus automatic, steel versus gold, and diamond-set and frosted variants, and shows how to match a case to your wrist. Bizak & Co. is a sourcing desk, not an authorised Audemars Piguet retailer, and nothing here is a stock listing.

Which Royal Oak sizes are made for smaller wrists?

Four case sizes cover the smaller end of the range: the 23 mm Royal Oak Mini (quartz, 18-carat gold only), 33 mm quartz, 34 mm Selfwinding and 37 mm Selfwinding. The 33 mm is the long-standing quartz model, the 34 mm Selfwinding arrived in 2020 as an automatic in a similar footprint, and the 37 mm Selfwinding is the larger automatic that many women wear as an everyday sports watch. The table sets out what we could confirm.

Is the 33 mm Royal Oak quartz or automatic?

The 33 mm Royal Oak is a quartz watch on the Audemars Piguet pages we reviewed. Some third-party listings describe a 33 mm automatic, but we could not confirm that on an Audemars Piguet page, so treat those as unverified and ask for the reference before you rely on them. Quartz means no winding and a very slim movement, which suits a small case. It also means a battery change every few years rather than a full service cycle.

What changed with the 34 mm Selfwinding?

The 34 mm Selfwinding gave the small Royal Oak a mechanical movement for the first time. It launched in 2020 in four versions: steel with a diamond-set bezel and a blue-grey dial, steel and pink gold, pink gold, and a plain-bezel steel option with a silver dial. Its Calibre 5800 is based on a Vaucher movement with a customised rotor and finishing, and shows hours, minutes, seconds and date. It is roughly the same footprint as the 33 mm but wears with more presence because of the integrated bracelet and the thickness of the case.

How does the 37 mm Selfwinding compare?

The 37 mm Selfwinding is the larger automatic, with the Calibre 5900 and a 60-hour power reserve. It is offered in steel with a diamond-set bezel, in gold, and in gem-set editions with a green or blue dial. It reads as a fuller sports watch and works well on medium and larger wrists, or for anyone who wants the proportions of the classic Royal Oak without moving up to the 41 mm men's size.

Quartz or automatic: which suits you?

Choose quartz if you want the smallest, lightest watch that you can leave in a drawer and wear again without resetting. Choose automatic if you value the mechanical movement, the date window and the longer power reserve. An automatic stops if unworn beyond its reserve, so a watch winder or regular wear helps. Both are serviceable by Audemars Piguet, and service costs are worth asking about before you buy either.

Should you choose steel or gold?

Steel is the lighter, more everyday option and is the classic Royal Oak look. Gold, whether pink, yellow or white, adds weight and warmth and is the choice for a dressier watch. Two-tone pink gold and steel sits between them. For sourcing, steel references are generally easier to match to a specific dial colour, while gold references vary more by year, so tell us whether the metal or the dial matters more.

What are the diamond-set and frosted versions?

Diamond-set Royal Oaks add brilliant-cut stones to the bezel and sometimes to the case and lugs, and a few editions add coloured sapphires. Frosted gold gives the case and bracelet a glittering, textured surface created with a hand-hammered technique first applied to the Royal Oak in 2016 with designer Carolina Bucci, for the 40th anniversary of the women's Royal Oak (the first pieces were shown to the trade at the Geneva fair in January 2017). Frosted pieces are offered in gold only. For more on each finish, see our guides to Audemars Piguet diamond watches and the Royal Oak in frosted gold.

Which size fits which wrist?

• Small wrists (roughly under 6 inches / 15 cm): start with the 33 mm quartz or 34 mm Selfwinding. The integrated bracelet does not taper much, so a smaller case keeps the lugs from overhanging.
• Medium wrists (roughly 6 to 7 inches): the 34 mm and 37 mm both work. The 34 mm looks neat and the 37 mm looks deliberate.
• Larger wrists (over about 7 inches / 18 cm): the 37 mm is the better balance, and some buyers look at the 41 mm in the men's line.

These are guidelines, not rules. Try the watch on, or compare against a watch you already wear, because the integrated bracelet changes how a given diameter feels. You can browse our Audemars Piguet Royal Oak ladies collection, the wider Audemars Piguet Royal Oak range and the Audemars Piguet brand collection for examples of each size.

Quick answers

What size is a women's Audemars Piguet Royal Oak?

Most women's choices are 33 mm quartz, 34 mm Selfwinding or 37 mm Selfwinding. Audemars Piguet does not label them as women's watches, so size and style are the deciding factors.

Is the 34 mm Royal Oak automatic?

Yes. The 34 mm Selfwinding launched in 2020 with the Calibre 5800, a self-winding movement with a 50-hour power reserve.

Is the 37 mm Royal Oak too big for a woman?

Not necessarily. It suits medium and larger wrists well and is a common choice for a bolder look. On a very small wrist, the 33 mm or 34 mm will sit more comfortably.

Which is better, quartz or automatic?

Neither is better for everyone. Quartz is slimmer and lower maintenance; automatic offers a mechanical movement and a date window. Pick on how you plan to wear it.

Can Bizak & Co. source a women's Royal Oak?

Yes. We source on demand, so tell us the size, metal and dial you want and we confirm the specific watch before you commit.
