What Is a Skeleton Watch?

Most watches hide their engine. A skeleton watch does the opposite: the dial is cut away, and often the bridges and plates of the movement too, until you can look through the watch and see the wheels turning and the balance swinging. It is watchmaking turned inside out, and it has fascinated buyers since the eighteenth century, when watchmakers began piercing movements to show off their craft.

The term covers more than people expect. A hand finished skeleton from a Swiss workshop, a mass produced automatic with an open dial and a quartz watch with a printed openwork pattern can all be sold as "skeleton", and they are very different things.

How is a skeleton watch made?

A movement is built on a base plate, with bridges screwed on top to hold the wheels in place. In a conventional watch these parts are solid, because solid metal is cheap to make and stiff. Skeletonizing removes every piece of that metal that is not structurally needed. The watchmaker leaves thin arms around each jewel and pivot, so the movement still holds its geometry, and cuts away the rest.

At the top of the trade this is done by hand with a fine saw, then each new edge is beveled and polished so it catches the light. That work can take weeks on a single movement, and it is why the best known skeleton automatics start at about $33,500. In industrial production the openings are stamped or machined and finished by machine. The result is less refined up close, but the effect at arm's length, of seeing the watch work, is the same.

Open heart, semi skeleton, full skeleton

Three kinds of "see through" watch turn up in shops, and it helps to have names for them.

Terms are used loosely by brands; judge by the photos, not the name.

An open heart is the gentlest version and the one most suited to a dress watch. A full skeleton is a statement, and it reads best in a case large enough to give the movement room.

Real skeleton or skeleton look?

This is the distinction that matters most when you buy at lower prices. A quartz movement is a small circuit board, a battery and a stepping motor. There is very little to see, so a quartz watch sold as "skeleton" usually shows decorative openwork plates or a printed pattern that imitates a mechanical movement. Nothing in it moves except the hands.

That is not a flaw if you know what you are buying. Quartz skeleton looks can be bold and colourful in a way a mechanical movement rarely is, and they keep perfect time without winding. The Lucky Fours Summit, with its barrel shaped case on a rubber strap, and the white cased Draco are both quartz watches designed around that kind of open, graphic dial. But if what draws you to the idea is watching a balance wheel swing, you want a mechanical movement.

Three quick checks tell them apart:

• The listing: look for "automatic", "mechanical" or "hand wound". "Skeleton design" alone usually means quartz.
• The seconds hand: a mechanical watch sweeps in small steps several times a second; a quartz seconds hand jumps once a second.
• The balance wheel: on a real skeleton you can find the round, oscillating wheel somewhere in the opening. In product videos it visibly swings back and forth.

What is it like to live with one?

A skeleton automatic is a watch you look at more than a watch you read. The hands need contrast to stand out against the wheels behind them, so check that they are a different colour or finish from the movement. A solid chapter ring around the edge of the dial helps more than you would expect.

Because it is automatic, it winds itself as you move, and it stops if left in a drawer for a day or two; how automatic watches work explains why. Accuracy at budget prices is measured in seconds a day rather than seconds a month. Dust and fingerprints on the crystal show more clearly over an open movement, so a soft cloth earns its place.

What does a skeleton watch cost?

The range is enormous. Hand finished full skeletons from the major Swiss houses start in the tens of thousands. Below that, Japanese and Chinese automatic movements made skeleton dials affordable, and there are now real mechanical skeletons under $200.

Lucky Fours sells three of them. The Lucky Fours Skeleton at $99.99 is a round steel case with a blue openwork dial on a steel bracelet. The Spine at $149.99 puts a similar open dial in an octagonal case, and the Prince Oak sets a gold toned movement inside a black octagonal case on rubber. All three are automatic. If you want an established name, an open heart model from one of the large Japanese makers is the usual next step up, and the full field is ranked in our guide to the best skeleton watches.
