The real assembly order

The first movement, the ETA 7750, is now built in the order a watchmaker would choose: 216 assembly steps, 23 of them sub-assemblies.

Runs in the development version. Shatterwork is not yet public.

Render from the teaching model: the mainplate with two wheels in place. Another part and its screw hover above their seat.
Part by part: the first wheels are in, the next part waits above its seat. Render from the teaching model.

A watchmaker does not simply put the parts into the movement one after another. Some of them are first put together on their own and then fitted as a whole. That is exactly how the first movement in Shatterwork, the ETA 7750 automatic chronograph, is now built.

216 steps, 23 sub-assemblies

The assembly follows 216 steps. 23 of them are sub-assemblies: small groups of parts that you prepare before they go into the movement.

The balance is one example. It goes onto the balance bridge first, and only then do you fit both together into the movement. The shock protection and the barrel are also built as sub-assemblies.

Closer to the real workbench

This brings the assembly in the game closer to a watchmaker’s work. The order is the one in which a movement is really put together.

The figures for the ETA 7750

  • 216 assembly steps
  • 23 sub-assemblies
  • 193 assembly units
  • 1,930 points to earn

These figures are for the first movement, as of October 2026. They may still change during development.
