What is the handle for?

The folding handle on top allows the clock to be carried safely during travel. It drops down flat when the clock rests on a mantelpiece or desk. Lifting the handle engages the internal locking mechanism in some travel versions, though many decorative pieces allow free movement.

How do alarm mechanisms work?

An auxiliary train drives a small hammer against an internal bell or gongs at a set time. Setting the alarm usually involves a small hand on a secondary dial. Owners wind the alarm spring separately from the main time train through a dedicated winding square on the backplate.

Why does the glass have bevels?

Thick bevelled edges add structural strength to the glass panels and refract light into the movement. This technique prevents simple flat panes from looking stark. The sloping edges also fit securely into the rebated brass channels of the corniche frame without rattling.
