How do I set the alarm on a carriage clock?

The alarm mechanism is typically set using a secondary winding arbor and a small auxiliary dial located on the backplate of the movement. Turning the hand or pointer to the desired hour engages the internal hammer to strike the bell or gong. Ensure the alarm spring is fully wound using the designated key square. When the hour hand reaches the set point, the mechanical trip releases the alarm train.

What is a gorge case?

A gorge case is a distinct architectural brass housing style characterised by its stepped top plate and concave moulding beneath the handle. This robust frame holds bevelled glass panels securely on all sides. Originating in nineteenth century French workshops, it often encloses movements with high-grade striking and repeating complications.

How do I wind an antique carriage clock?

Winding requires a matching double-ended key fitted to the arbors on the backplate. Timekeeping, striking, and alarm functions each have separate arbors that require gentle tension. Care must be taken not to over-wind the mainsprings. Most nineteenth century movements operate for eight days on a full wind.

What is the difference between petite sonnerie and grande sonnerie?

A petite sonnerie strikes the hours on the hour and only the quarters on the quarter hours without repeating the hour. A grande sonnerie strikes both the hours and the current quarters every time the quarter chimes sound. Both systems represent high levels of nineteenth century horological complexity.

Are original leather cases common?

Original leather travel cases survive with select pieces, designed to protect the brass housing and glass panels during transit. These fitted cases often feature velvet or silk linings and cutouts for the winding key. Finding a clock with its matching box adds significantly to the historical completeness of the object.
