What is the difference between a Full Skeleton and an open-heart?

An open-heart usually cuts a small window over the balance wheel and keeps most of the dial. A Full Skeleton removes the dial entirely and hollows the bridges to a functional minimum, so the whole movement reads front to back. Partial openworking sits between the two as a middle step.

Is a Full Skeleton watch legible?

It is inherently low-contrast, since the hands sit over a busy moving backdrop rather than a solid dial. Choose a piece where the hour and minute hands stand clear, ideally with blued steel or lumed tips, and day-to-day reading is fine. Simple three-hand skeletons are usually the easiest to read.

What is the cheapest real Full Skeleton?

Automatic, genuinely mechanical full skeletons start around £900; the Tissot Chemin des Tourelles Squelette at roughly £870 and the Hamilton Jazzmaster Skeleton near £1,000 are solid entry points. Cheaper open-heart pieces exist, but those expose only the balance and do not count as full skeletons.

Does exposing the movement make a skeleton less durable?

On a well-made full skeleton, enough of the mainplate and bridges remain to preserve rigidity, so everyday wear is no problem. But with a glass front in place of a dial and often limited water resistance, treat these as watches for daily elegance rather than diving or heavy impact.

How do I tell an expensive skeleton from a cheap one?

Look at finishing: chamfered bridge edges, polished screw heads and real hand anglage versus metal that has simply been laser-cut. The movement's origin matters too, since an in-house calibre carries more craft and value than a Sellita or ETA base. Cheap pieces hollow the metal but skip the handwork.

Full Skeleton Watches: Models, Prices & Buying Guide

Full Skeleton sits at the far end of the openworking spectrum. An open-heart watch cuts a small window over the balance wheel, and partial openworked designs leave parts of the movement covered, but a Full Skeleton strips the dial entirely and hollows the mainplate and bridges to their functional minimum, so the wheel train, mainspring barrel and bridge architecture read straight through from front to back. The technique traces to French watchmaker Andre-Charles Caron around 1760, clockmaker to Louis XV, who pierced and engraved plates to show the movement's inner workings. That hand still matters: a good full skeleton is an exercise in how far you can remove metal without compromising rigidity.

Real examples show the range. The Audemars Piguet Royal Oak Double Balance Wheel Openworked (41mm steel, ref 15407ST) displays two superimposed balance wheels on one axis; AP's list price sits near £60,000, while the secondary market often runs £105,000 to £160,000, and the rose gold 15407OR approaches £175,000. The Cartier Santos de Cartier Skeleton turns its bridges into the Roman numerals for 12, 3, 6 and 9, doing the job of a dial, with the manual-wind calibre 9611 MC, and lands roughly £18,000 to £44,000 by metal. The H. Moser & Cie Streamliner Tourbillon Skeleton (2024) frames a flying tourbillon in a 40mm steel cushion case with the HMC 814 at about £70,000. Lower down, the Tissot Chemin des Tourelles Squelette is around £870 and the Hamilton Jazzmaster Skeleton sits near £1,000.

When buying, weigh three things. First, finishing: look for chamfered bridge edges, polished screw heads and real anglage rather than metal that has simply been laser-cut, because that is where cheap skeletons give themselves away. Second, legibility, since a full skeleton is inherently low-contrast; find a piece where the hands stand clear against the busy backdrop, and blued steel or lumed tips help. Third, the movement's origin, because a Sellita or ETA-based skeleton can be lovely, but an in-house calibre carries different craft and value. The style suits a collector who wants the mechanics on show and high case-back drama on the wrist.

Keep in mind that Full Skeleton is a degree, not a sub-type. The range runs from clean, machine-finished modern readings like the Royal Oak to hand-engraved filigree in the 19th-century spirit. Add a tourbillon or perpetual calendar and the price climbs fast: a piece like the Vacheron Constantin Overseas Skeleton reaches around £120,000. For anyone after restraint, a simple three-hander skeleton already delivers plenty of theatre.
