Barrel

Cylindrical container housing the mainspring. As it unwinds, the barrel rotates and drives the gear train.

Bezel

The ring surrounding the watch crystal. Can be fixed or rotating.Example: The Rolex Submariner has a unidirectional rotating bezel for dive timing.

Blued Hands

Steel hands heated to ~290°C until oxidation turns them vivid blue. A hallmark of fine watchmaking.

Caliber

The specific movement used in a watch. Each has a unique reference number.Example: Rolex Caliber 3235 powers the Datejust 41.

Caseback

The rear cover of a watch case. Can be solid or transparent/exhibition.

Chapter Ring
