## Hands The clock has three hand rotors: **Hour**, **Minute**, and **Second**. Each hand has its own physical angle, visibility, style, Drive definition, and local Motion pipeline. A hand does not inherently have to behave like a conventional clock hand; its behavior depends on the movement configuration assigned to it. A hand may be independently driven by Clock, Fixed, Free, or Coupled Drive. Alternatively, it may be the **Time slave** of the bezel in the same lane. In that case it gives up independent Drive authority and its pre-Motion target is derived from the bezel so that the pair's relative angle indicates the configured time. Motion remains local even when a hand is a Time slave or is Coupled to another rotor. Only its Drive target is derived; its Timing, Advance, Response, and Modulation settings remain its own. ## Bezels Each lane also has a bezel rotor: **Hour**, **Minute**, and **Second**. A bezel is a rotating reference frame carrying its marks and labels. Like a hand, it has an independent physical angle, visibility, appearance, Drive definition, and Motion pipeline. Time is encoded by the **relative angle between a hand and its bezel**, not by either rotor alone. This is why moving a bezel can compensate for, oppose, or become the authoritative partner of a moving hand while the lane still represents time. Bezels have one capability hands do not: an **Epicycle** stage. Epicycle changes the position of the bezel's center by orbiting it around the main clock center. The bezel still rotates according to its independently resolved Drive and Motion trajectory while its center moves. Bezel order is a display choice. It changes how the concentric bezel rings are arranged but does not rewrite the underlying movement definitions. ## Position **Position** describes the visible pose of the clock at a particular moment. The Clock page reports three related quantities for each lane: the physical Hand position, the Bezel anchor position, and the Time indicated by their relationship. The Position controls provide three direct actions: - **Default** restores the canonical starting pose. - **10:10:35** places the Hour hand exactly at 10 o'clock, the Minute hand at 10 minutes, and the Second hand at 35 seconds as independent lane positions. - **Random** chooses new hand positions. These actions reposition the mechanism without rewriting authored Drive, Motion, or Epicycle settings. They are therefore different from changing a Drive mode or editing a movement parameter. Position randomization can also schedule repeated changes independently for Hour, Minute, and Second. Each lane has its own enable state and interval. Scheduled changes use the same position-setting mechanism as the Random action and leave the authored movement pipeline intact.
